Parskey, J.
After a trial to the jury, the defendant was convicted of three counts of murder and was sentenced by the court to three terms of imprisonment of twenty-five years to life, such sentences to run consecutively, for a total effective sentence of seventy-five years to life. In his appeal the defendant claims that his conviction was vitiated by (1) the denial of his motion [532]*532to suppress certain evidence seized in violation of his rights under the fourth amendment; (2) the composition of the grand jury and the conduct of its proceedings; (3) the court’s unauthorized amendment of the indictment; and (4) the prejudicial summation of the prosecutor. The defendant also claims that the consecutive sentences which the court imposed were illegal.
The jury could reasonably have found the following facts. On the early morning of April 16,1979, the police were called to the Purolator Armored Car garage in Waterbury where three guards, Leslie Clark, Edward Cody and William West, were found shot to death. Each body suffered multiple gunshot wounds, and the exterior and interior of the garage were littered with 24 expended 30 caliber shell casings fired from two M-l semi-automatic carbines. The truck which Cody and West had driven from Hartford early that morning into the Waterbury garage where Clark was working alone was riddled with bullet holes, and its contents, a shipment of approximately 1.8 million dollars in cash, checks, food stamps and jewelry, were missing.
Late in the afternoon of April 16, 1979, Patricia Dolphin came to the police with information that she had purchased an Iver Johnson M-1 carbine, serial number AA05518, at the request of Evelyn Vega for Lawrence Pelletier of Waterbury. Mrs. Dolphin related that Pelletier had been recently planning an armed robbery of the Purolator garage with a “Donald” whom Pelletier would talk to on the telephone. Mrs. Dolphin did not then know Donald’s last name, but at the trial Mrs. Dolphin later identified Donald Couture as “Donald.”
Acting on this information, the police sought a search warrant for the Waterbury home of Lawrence Pelletier to search for the murder weapons, other tools and the stolen armored car shipment. They also sought a war[533]*533rant for Lawrence Pelletier’s telephone toll records. The search warrants were issued very early on the morning of April 17 and they were executed shortly thereafter.
Found at Pelletier’s home where Pelletier and Evelyn Vega lived were an attache case containing money, literature for a 30 caliber M-l carbine and two expended shell casings ejected from the same M-l carbine fired at the murder scene. The weapon itself and the robbery loot were not, however, at the Pelletier home.
The telephone toll record search revealed that Lawrence Pelletier often called a Donald Couture of Wallingford. On the basis of this and other information, during the early morning hours of April 17,1979, the police sought a search warrant for Couture’s premises in Wallingford. The search warrant was issued, and before dawn on the 17th the police entered the home of Donald Couture. There they found Donald Couture hiding under his bed. In the basement of that home were located the stolen armored car shipment, consisting of approximately $1,800,000 in cash, checks, food stamps, jewelry, empty deposit bags, and deposit slips made out by Purolator customers and a gun locker containing two 30 caliber M-l carbines. Couture was later found to have the key to the gun cabinet on his key chain.
The two M-1’s, one an Inland Marine model and the other the Iver Johnson, serial number AA05518, bought for Pelletier, were examined and compared with expended cartridge cases and bullets found at the Purolator garage and with bullets recovered from the bodies and clothing of the slain guards. These latter bullets did not, as did other bullets, pass through the guards’ bodies. Ten of the ejected cartridge cases at the murder scene came from the Iver Johnson carbine and fourteen had been ejected from the Inland Marine [534]*534carbine. Bullets from the bodies of all three victims had been fired from the Iver Johnson carbine and bullets from the bodies of Leslie Clark and Edward Cody had been fired from the Inland Marine weapon. Six bullet jacket fragments and one bullet fired from the Inland Marine weapon were also found at the Purolator garage, as well as two such fragments fired from the Iver Johnson carbine. These bullets and fragments were bloody.
On April 12,1979, the Inland Marine M-1 carbine had been purchased under a fictitious name from the North Haven Gun Company by Donna Couture as a gift for her husband, the defendant. On April 13, Pelletier and Donald Couture were seen going into the woods near Wallingford and a great number of shots were heard in those woods. A bullet and seven expended cartridge cases recovered from the woods were found to have been fired from the Iver Johnson and one such expended cartridge case was found to have been ejected from the Inland Marine M-1 carbine.
A pair of Hit 800 bolt cutters was also found in the defendant’s gun locker. These cutters had been used to cut a Page metal fence surrounding the Purolator garage to allow entry into the area. These same cutters had previously been borrowed from a Waterbury neighbor of Lawrence Pelletier by Pelletier’s son. Found in Couture’s basement gun locker were also two ski masks with the eye openings narrowed by thread which Pelletier’s girlfriend, Evelyn Vega, had prepared for the robbery, as well as trousers recognized as Pelletier’s. In Couture’s gun locker the police also found an attache case, of the same type as the one found in Pelletier’s house, filled with money. A footlocker was also found in Couture’s basement together with store boxes for the two attache cases. All three pieces of luggage had been purchased by Pelletier and Vega on April 16.
[535]*535The jury heard evidence that when the police found the money in Couture’s home one officer stated: “We found the money,” at which time the defendant stated: “Anybody could have put it in the basement,’’although no one had stated where the money had been found.
Donald Couture’s defense consisted of cross-examination of the state’s witnesses and the presentation of three defense witnesses. One defense witness was Hurlburt Dolphin, a brother-in-law of Patricia Dolphin, who attacked the credibility of Patricia Dolphin and stated Mrs. Dolphin once asked him for firearms. A second defense witness was Barbara Ranando of the Colonial Bank and Trust Company who identified a bank deposit bag found with the robbery loot as a Colonial Bank deposit bag given in 1975 to Richard Demonte, the last Couture witness. Demonte testified he had been a partner of the defendant, Donald Couture in a luncheonette business which closed in 1975.
I
Seizure of Evidence
On April 16, 1979, three guards of Purolator Security, Inc., were murdered and over 1.7 million dollars worth of U.S. currency, jewelry and other items were stolen in an armed robbery at the Purolator Security (Purolator) building at 20 Dunbar Lane, Waterbury. On April 17,1979, pursuant to a search warrant issued by Judge Henebry, law enforcement authorities entered the defendant’s residence at 227 Hall Avenue in Wallingford and seized, inter alia, two M-1 carbine rifles and seven bags of currency containing more than $800,000. The defendant challenges the seizure on the grounds that (1) there was insufficient probable cause for the issuance of the search warrant and (2) the currency was not properly seized under the plain view doctrine. We disagree.
[536]*536A
PROBABLE CAUSE TO SEARCH
“Under existing law, valid warrants may be issued to search any property ... at which there is probable cause to believe that fruits, instrumentalities, or evidence of a crime will be found.” (Emphasis in original.) Zurcher v. Stanford Daily, 436 U.S. 547, 554, 98 S. Ct. 1970, 56 L. Ed. 2d 525, reh. denied, 439 U.S. 885, 99 S. Ct. 231, 58 L. Ed. 2d 200 (1978). Whether there is probable cause is to be determined upon facts stated in the affidavit purporting to establish grounds for issuing the warrant. United States v. Harris, 403 U.S. 573, 579, 91 S. Ct. 2075, 29 L. Ed. 2d 723 (1971); State v. DeChamplain, 179 Conn. 522, 530, 427 A.2d 1338 (1980). In considering the sufficiency of the affidavit we confine ourselves to the facts which appear on the face of the affidavit or which properly may be inferred therefrom; State v. Williams, 170 Conn. 618, 629, 368 A.2d 140, cert. denied, 429 U.S. 865, 97 S. Ct. 174, 50 L. Ed. 2d 145 (1976); testing those facts with common sense and reality; United States v. Ventresca, 380 U.S. 102, 108, 85 S. Ct. 741, 13 L. Ed. 2d 684 (1965); and with great deference to the fact that the issuing magistrate did determine that probable cause existed. Jones v. United States, 362 U.S. 257, 270-71, 80 S. Ct. 725, 4 L. Ed. 2d 697 (1960). The limited issue in the present case is whether it was reasonable to infer from the facts appearing in the affidavit that the weapons which were used in the robbery and murder at Purolator would be found at the defendant’s residence.
When a warrant is sought to search specific premises for certain objects the information appearing in the affidavit should demonstrate a nexus between the objects to be seized and the premises to be searched. United States v. Charest, 602 F.2d 1015, 1017 (1st Cir. [537]*5371979). That nexus “[does] not have to rest on direct observation, but can be inferred from the type of crime, the nature of the items sought, the extent of an opportunity for concealment and normal inferences as to where a criminal would hide a [weapon] used in the commission of a murder.” Id.; see United States v. Lucarz, 430 F.2d 1051, 1055 (9th Cir. 1970); Mills v. State, 278 Md. 262, 363 A.2d 491 (1976); Bollinger v. State, 556 P.2d 1035 (Okla. Crim. App. 1976).
The affidavit1 stated that on April 16, 1979, a murder and robbery occurred at the Purolator Security office in Waterbury and about 1.7 million dollars and [538]*538other items were stolen. It further stated that on that same day Patricia Dolphin, a friend of Eyelyn Pelletier, the live-in girl friend of Lawrence Pelletier, related to the affiant in specific detail that the defendant and Lawrence Pelletier planned, cased and participated in the Purolator robbery, that they had gained access to the Purolator garage building using wire and bolt cutters, and that Pelletier borrowed the wire cutters from a neighbor and stated to Dolphin that the cutters were [539]*539needed to cut the wires on the fence for the “job.” It also stated that the type of weapon used in the murder of the three Purolator guards was an M-l carbine rifle, that on April 7, 1979, Dolphin, at Evelyn Pelletier’s request, purchased an M-l carbine rifle which, according to a forensic ballistics expert had been used in the murder, and that spent shell casings from such rifle were found at the scene of the crime and matching casings were found, pursuant to a search warrant, at Pelletier’s residence but that no carbine rifle was found there. The affidavit did not mention the recovery of any of the stolen money, but it did further state [540]*540that Pelletier, according to Dolphin, customarily uses a 1970 green Dodge with a black top, that this vehicle was observed by Detective Bouley at the Pelletier premises on the evening of April 16, 1979, and that the defendant, who had according to Dolphin participated with Pelletier in numerous crimes in the past, had no police record. The issuing magistrate, Henebry, J., found that there was probable cause to believe that the items referred to in the affidavit would be found either on the person of the defendant or at his residence in Wallingford.
[541]*541The crime occurred on April 16, 1979. The application and affidavit were submitted to the issuing magistrate in the very early hours of the next day. Included in the items stolen from Purolator were almost two million dollars of U.S. currency. With that huge amount [542]*542of money to secrete, the magistrate could infer that the perpetrators were faced with the elephant dilemma (where do you hide an elephant?). An earlier search of the Pelletier residence uncovered neither the weapon [543]*543nor the huge amount of stolen money. That the search warrant, for whatever reason, did not authorize a search for the money does not mean that the magistrate could not utilize the information and inferences respecting the money in drawing an inference concerning the likely location of the murder weapon. In these circumstances it was reasonable for the issuing magistrate to infer that the money, because of its bulk and because of the time constraints, would likely be stored at a convenient “safe” house. United States v. Lucarz, supra. It is also a logical inference that a criminal who believes his identity is concealed would utilize his residence as such a safe place; Bollinger v. State, supra, 1039; not only for storage of the loot but also as a temporary depository for the weapon used in the crime. The magistrate could consider that the defendant had [544]*544no reason to suspect that, at that early stage, the investigative probe would move in his direction. He had participated with Pelletier in other crimes in the past and had remained unscathed. Although with the passage of time the situation might change; United States v. Charest, supra, 1018; at the time of the issuance of the warrant it was reasonable for the magistrate to infer that the defendant’s residence was the logical place to conceal not only the fruits but also the instrumentalities of the crime. 1 LaFave, Search and Seizure, A Treatise on the Fourth Amendment § 3.7, p. 709. “In considering the situation realistically, the logical inference is that a criminal, who believes his identity has been concealed, would return [the weapon] and property to his home. Such an inference is not certainty, but a certainty is not required. And, we are of the opinion that, at the least, a probability existed that the property sought was indeed at the residence of the defendant.” Bollinger v. State, supra, 1039.
State v. DeChamplain, supra, does not require a different result. In that case, we held that the affidavit was insufficient to support a finding of probable cause that marihuana was located in the defendant’s apartment. There the affidavit revealed that a drug transaction was arranged over the phone located in the apartment. The police then observed the defendant leave the building in which the apartment was located, enter a car parked near the building, drive directly to the designated meeting place and consummate the transaction. Id., 524-25. The affidavit did not state whether, when the defendant left the apartment building, he was carrying a package. Id., 532. We concluded that these observations of activity around the building did not sufficiently support the conclusion that there was probable cause to believe that there was marihuana in the apartment. Id., 530.
[545]*545In DeChamplain there was not enough evidence connecting the marihuana with the apartment. In the present case the affidavit contained substantial facts from which the magistrate could conclude that there was probable cause to believe the weapon was located in the defendant’s house. The magistrate knew from the affidavit that a search of Pelletier’s house had not revealed the money or the weapon. He also knew that the amount of money was substantial and hence not easily disposed of. Further, the magistrate knew that the defendant had no criminal record. From this the magistrate could reasonably infer that the defendant believed his identity was unknown and that his house was at least temporarily a secure place in which to store the money. These reasonable inferences would have sufficed to establish probable cause to believe that the money would be found at the defendant’s home. In contradistinction to DeChamplain, therefore, the defendant’s residence was factually implicated in the defendant’s criminal activity.
The affidavit also disclosed that the murder weapon was recently purchased and bore a serial number which made it easily traceable to Pelletier. The magistrate could reasonably infer that the defendant would have an interest in secreting this weapon or dismantling it, before it could be associated with the defendant. The magistrate was aware that all of this had to be accomplished in the relatively short period of time that had elapsed since the crime, and in a safe place. It was reasonable for the magistrate to conclude that, if the defendant believed that his house was a safe place for the money, it was also a safe place temporarily to hide the weapon. “Where the object of the search is a weapon used in the crime . . . the inference that the items are at the offender’s residence is especially compelling, at least in those cases where the perpetrator [546]*546is unaware that the victim has been able to identify him to the police.” 1 LaFave, Search and Seizure, supra.
In reviewing the sufficiency of an affidavit for a search warrant we do not conduct a de novo review. Illinois v. Gates, 462 U.S. 213, 103 S. Ct. 2317, 76 L. Ed. 2d 527, reh. denied, 463 U.S. 1237, 104 S. Ct. 33, 77 L. Ed. 2d 1453 (1983). Rather, the traditional standard of review is whether the magistrate had a substantial basis for concluding that a search would uncover evidence of wrongdoing. Id. In considering the quantum of certainty required, it is only a probability, and not a prima facie showing of criminal activity, that is the standard of probable cause. United States v. Travisano, 724 F.2d 341, 346 (2d Cir. 1983). If there is a fair probability that the premises to be searched will yield the objects specified in the search warrant, the fourth amendment has been satisfied even where many localities were available to the guilty parties to secrete the fruits and instrumentalities of the crime. Id. Applying these standards, we agree with the trial court that there was a substantial basis for the issuing magistrate to conclude that the weapon used in the murder would be found at the defendant’s residence.2
B
SEIZURE OF MONEY - PLAIN VIEW
Given the lawful entry of the police into the defendant’s residence pursuant to a valid search warrant the next question is whether they were justified in seizing the money which was observed in a number of trans[547]*547parent bags. The defendant argues that under Coolidge v. New Hampshire, 403 U.S. 443, 91 S. Ct. 2022, 29 L. Ed. 2d 564, reh. denied, 404 U.S. 874, 92 S. Ct. 26, 30 L. Ed. 2d 120 (1971), the police could seize under the plain view doctrine only articles which they came upon inadvertently and that the money was not in that category, since in their application they sought permission to search for the money but that the warrant contained no such authority. While it is true that seizure of items in plain view is limited to those items which police come upon inadvertently, inadvertence is not required if the items seized fall under the category of contraband, stolen property or objects dangerous in themselves. See Coolidge v. New Hampshire, supra, 466; United States v. Liberti, 616 F.2d 34, 38 (2d Cir. 1980) (Newman, J., concurring); State v. Gold, 180 Conn. 619, 649, 431 A.2d 501, cert, denied, 449 U.S. 920, 101 S. Ct. 320, 66 L. Ed. 2d 148 (1980). The seizure of the seven bags of U.S. currency was valid.
II
On August 29,1979, the defendant filed an omnibus motion to dismiss the indictment which challenged, inter alia, (1) the underrepresentation of certain groups on Waterbury grand juries;3 (2) the presence and par[548]*548ticipation of unauthorized persons in the grand jury proceedings; and (3) the withholding of allegedly exculpatory evidence from the grand jury. The trial court, Pickett, J., denied the motion and the defendant assigns this as error.
A
CHALLENGE TO GRAND JURY ARRAY
The defendant claims that the underrepresentation of Hispanics4 on grand juries in the judicial district of Waterbury violated his rights to equal protection and due process as provided by the fourteenth amendment to the United States constitution and as a result the indictment should have been dismissed. In support of his claim the defendant presented the following relevant evidence. During the period of January 1, 1973, until June 6, 1979, the date of the defendant’s indictment, there were thirty-four grand juries in the judicial district of Waterbury. Of the 612 grand jurors composing the array, only six or .98 percent were Hispanic. The Hispanic population during the relevant period constituted 4.5 percent of the population of the judicial district of Waterbury.5
The trial court, in an exhaustive memorandum of decision, held that since the defendant was not Hispanic he had no standing to raise an equal protection challenge. It further concluded that the defendant could not raise a due process challenge because the sixth amendment requirement that state juries reflect a fair cross-section of the community was inapplicable to state grand juries. The court reasoned that unlike the sixth amendment, the grand jury provisions of the fifth [549]*549amendment have not been made applicable to the states by the due process clause; Hurtado v. California, 110 U.S. 516, 4 S. Ct. 111, 28 L. Ed. 232 (1884); and therefore any right to a representative grand jury applies only to federal grand juries. Consequently, the court did not reach the issue of whether the disparity between the percentage of Hispanics in the population and their representation on the array was constitutionally significant.
We agree with the trial court that the defendant’s equal protection claim is not cognizable. It is well settled that in order to bring such a challenge, the defendant must be a member of the underrepresented class. Castaneda v. Partida, 430 U.S. 482, 494, 97 S. Ct. 1272, 51 L. Ed. 2d 498 (1977). We do not agree, however, that the defendant is precluded from raising a due process challenge.
Although a state is not required to utilize a grand jury as part of its criminal justice system, when it chooses to do so it must “hew to federal constitutional criteria.” Carter v. Jury Commission of Greene County, Alabama, 396 U.S. 320, 330, 90 S. Ct. 518, 24 L. Ed. 2d 549 (1970); Cobbs v. Robinson, 528 F.2d 1331, 1334 (2d Cir. 1975), cert. denied, 424 U.S. 947, 96 S. Ct. 1419, 47 L. Ed. 2d 354 (1976); State v. Cobbs, 164 Conn. 402, 407, 324 A.2d 234, cert. denied, 414 U.S. 861, 94 S. Ct. 77, 38 L. Ed. 2d 112 (1973). In Peters v. Kiff 407 U.S. 493, 502, 92 S. Ct. 2163, 33 L. Ed. 2d 83 (1972) (plurality opinion), the court recognized a due process challenge to a state grand jury, without requiring the defendant to be a member of the underrepresented class. “[A] [sjtate cannot, consistent with due process, subject a defendant to indictment or trial by a jury that has been selected in an arbitrary and discriminatory manner, in violation of the Constitution and laws of the United States. Illegal and unconstitutional jury selection procedures cast doubt on the integrity of the whole [550]*550judicial process.” Though this holding commanded only three votes,6 it has never been overruled. Indeed, its vitality has most recently been affirmed in Hobby v. United States, 468 U.S. , 104 S. Ct. 3093, 3097, 82 L. Ed. 2d 260 (1984).
This court has implicitly acknowledged the applicability of the due process clause to the selection of the grand jury. Just this term in State v. Castonguay, 194 Conn. 416, 481 A.2d 56 (1984), we exhaustively considered the defendant’s due process challenge to the composition of the grand jury. Previously, in State v. Cobbs, supra, 407-11, we discussed the defendant’s claim that the grand jury was not drawn from a fair cross-section of the community. See also State v. Reinosa, 29 Conn. Sup. 117, 274 A.2d 452 (1970).
We recognize that there is some authority for the trial court’s position. See, e.g., Castaneda v. Partida, supra, 509 (Powell, J., dissenting); Villafane v. Manson, 504 F. Sup. 78, 82 n.6 (D. Conn.), aff d without opinion, 639 F.2d 770 (2d Cir. 1980);7 State v. Acosta, 125 Ariz. 146, 608 P.2d 83 (1980); Commonwealth v. Bastarache, 414 N.E.2d 984 (Mass. 1980). The clear weight of authority is, however, to the contrary. See, e.g., Obregon v. [551]*551United States, 423 A.2d 200 (D.C. App. 1980), cert. denied, 452 U.S. 918, 101 S. Ct. 3054, 69 L. Ed. 2d 422 (1981); Colvin v. Commonwealth, 570 S.W.2d 281 (Ky. 1978); State v. Lawrence, 351 So. 2d 493 (La. 1977); Adler v. State, 594 P.2d 725 (Nev. 1979); State v. Porro, 158 N.J. Super. 269, 385 A.2d 1258 (1978); People v. Guzman, 60 N.Y.2d 403, 409 n.3, 457 N.E.2d 1143, 469 N.Y.S.2d 916 (1983), cert. denied, 466 U.S. 951, 104 S. Ct. 2155, 80 L. Ed. 2d 541 (1984); State v. Bowen, 45 Or. App. 17, 607 P.2d 218 (1980); State v. Jenison, 405 A.2d 3 (R.I. 1979); Post v. State, 580 S.W.2d 801 (Tenn. Crim. App. 1979). We hold that the defendant’s due process challenge to the composition of the grand jury is cognizable. Accordingly, we will consider the merits of that claim.
In State v. Castonguay, 194 Conn. 416, 421-22, 481 A.2d 56 (1984), we set out the proper analysis for a fair cross-section challenge: “ ‘In order to establish a prima facie violation of the fair-cross-section requirement, the defendant must show (1) that the group alleged to be excluded is a “distinctive” group in the community; (2) that the representation of this group in venires from which juries are selected is not fair and reasonable in relation to the number of such persons in the community; and (3) that this underrepresentation is due to systematic exclusion of the group in the jury-selection process.’ Duren v. Missouri, [439 U.S. 357], 364, [99 S. Ct. 664, 58 L. Ed. 2d 579 (1979)]. Once the defendant has established this prima facie case, the burden then shifts to the state to prove that the selection system resulting in a nonrepresentative array furthers a significant state interest. Id., 367.”
It is beyond dispute that Hispanics constitute a distinct group in the community. Id., 424; State v. Villafane, 164 Conn. 637, 325 A.2d 251 (1973). The defendant has satisfied this element of his burden of proof.
[552]*552It is in the second element, proof of substantial under-representation; State v. Castonguay, supra, 425-26; State v. Haskins, 188 Conn. 432, 440, 450 A.2d 828 (1982); that the defendant fails. In Castonguay, supra, 427-30, we examined various methods used to describe and evaluate underrepresentation. We concluded that in a due process challenge where the distinct group constitutes a small percentage of the population in the community, the most accurate method is the substantial impact test. “Its focus is not on numbers and percentages but rather on whether the underrepresentation substantially affects the composition of the grand jury.” Id., 430. When we apply that method to this case, the defendant cannot prevail.
The grand jury array during the relevant period was composed of 612 grand jurors. If the array reflected the number of Hispanics in the judicial district (4.5 percent), it should have included approximately twenty-eight Hispanics (4.5 percent of 612). The array included six Hispanics. Hispanics were therefore underrepresented by almost twenty-two grand jurors. In substantial impact terms, slightly more than one Hispanic should have been included on every other grand jury. Since “only ‘gross’ or ‘marked’ disparities or ‘substantial’ departures from a ‘fair cross section’ require judicial intervention”; United States v. Test, 550 F.2d 577, 590 (10th Cir. 1976); we cannot conclude that this underrepresentation is constitutionally significant. Cf. State v. Castonguay, supra, 430-31.
PRESENCE AND CONDUCT OF UNAUTHORIZED PERSONS BEFORE THE GRAND JURY
During the course of the grand jury proceedings, counsel for the defendant and counsel for his codefendant Lawrence Pelletier requested the trial court’s permission to accompany their clients in the grand jury room [553]*553during the taking of testimony. The court ruled that any of the accused called as a witness had the right to an attorney’s presence during the time he or she was testifying, but none of the defendant’s attorneys would otherwise be permitted to attend the proceedings. The court explicitly instructed the grand jury: “In the event that any of the accused is called as a witness, your foreman or forelady shall instruct that person that he or she has a right to remain silent, right to consult and have an attorney present and a right to stop answering any questions at any time without giving any reason .... If an attorney is present, he shall not participate in the questioning but rather be present for the sole purpose of conferring with his or her client. When the witness has finished testifying counsel shall be excused from the Grand Jury room.” The defendant did not object to this instruction.
Since the defendant did not testify, his counsel was not present in the grand jury room at any time. His codefendants Evelyn Vega and Donna Couture did testify, however, and their respective attorneys, David Rosen and Hugh Keefe, were permitted by the court to be present during their testimony. The defendant, whose counsel was present when permission was granted, did not object. In disregard of the trial court’s express instructions, both counsel participated in the questioning of their clients. The defendant claims that the attorneys’ presence and conduct require dismissal of the indictment.
The first aspect of the defendant’s claim is addressed to the trial court’s action in authorizing the attorneys’ presence. The defendant urges us to adopt a per se rule similar to that in the federal courts; see, e.g., United States v. Phillips Petroleum Co., 435 F. Sup. 610, 618 (N.D. Okla. 1977), and cases cited therein; and hold that the presence of any unauthorized person in the grand jury room vitiates the indictment. The defendant has [554]*554failed to preserve properly this claim for appeal. Though he had ample opportunity to do so, at no time did the defendant object to the trial court’s decision to permit the attorneys’ presence. Practice Book § 288.
The issue of who is authorized to be present in the grand jury room is a matter of practice embodied in Practice Book § 609.8 It does not implicate a fundamental constitutional right. Consequently, the defendant, having failed to object below, cannot claim error on appeal. See Practice Book § 3063.
Nor can we consider the second aspect of the defendant’s claim, that the attorneys, in disregard of the trial court’s instructions, elicited testimony from their clients. In support of his claim that he was prejudiced by this questioning the defendant relied on the transcript of the grand jury proceedings.9 This he cannot do.
At the time of the offense, General Statutes (Rev. to 1979) § 54-45a limited the evidentiary use of the grand jury transcript in any proceeding against the accused to “impeaching a witness, attacking the credibility of a witness or proving inconsistent statements of a witness. Such transcript may also be used as evidence in a prosecution for perjury committed by a witness while giving such testimony.” In State v. Canady, [555]*555187 Conn. 281, 287, 445 A.2d 895 (1982), we construed the substance10 of this statute strictly and concluded that a defendant may not prevail on claims of error that depend on the unauthorized use of the grand jury transcript. Because the defendant’s use of the grand jury transcript is not authorized by the statute we cannot consider this claim.11
C
EVIDENCE NOT PRESENTED TO THE GRAND JURY
The state and the defendant have stipulated that certain information12 was withheld from the grand jury. The defendant claims that it was exculpatory and that because it was withheld from the grand jury his indictment should be dismissed. There is no merit to this claim.
[556]*556Since the grand jury does not consider the guilt or innocence of the accused but only determines whether he or she should stand trial, the accused “is not allowed to testify or to introduce evidence tending to prove his innocence except insofar as his questioning of the state’s witnesses may disclose the weakness of the state’s case.” State v. Menillo, 159 Conn. 264, 274-75, 268 A.2d 667 (1970); State v. Stepney, 181 Conn. 268, 274, 435 A.2d 701 (1980), cert. denied, 449 U.S. 1077, 101 S. Ct. 856, 66 L. Ed. 2d 799 (1981). The purpose of the grand jury is not to duplicate the trial but rather to satisfy itself that “there is probable cause to believe that the accused is in danger of conviction of [the crime charged].” State v. Menillo, supra, 275.
[557]*557The Connecticut grand jury system is almost unique in that the state’s role in the proceedings is minimal. The state’s attorney is not permitted in the grand jury room and his task is confined to submitting to the grand jury a list of witnesses who he believes will testify in support of the indictment. The grand jury is not at all bound by this list. Id., 276; see Lung’s Case, 1 Conn. 428 (1815); Practice Book § 614. The defendant, with the court’s permission, is allowed in the room during the presentation of evidence; Practice Book § 609; and can question the witnesses. Thus, unlike in the federal system and in other states, the grand jury is not dependent on the state’s attorney for both advice and information. See, e.g., United States v. Ciambrone, 601 F.2d 616, 622 (2d Cir. 1979); Frink v. State, 597 P.2d 154 (Alaska 1979). Consequently, in the absence of a request by the grand jury, the state is not obligated to present the grand jury with every piece of relevant information.
We do believe, however, that since the state has no interest in accusing the wrong person, it is obliged to present the grand jury with any substantial evidence that would negate the accused’s guilt, that is evidence which “might reasonably be expected to lead the jury not to indict.” United States v. Ciambrone, supra, 623. It is unnecessary for us to discuss each piece of information contained in the stipulation. Suffice it to say that we have examined the information and conclude that none of it would have precluded a finding of probable cause. We find no error.
Ill
“Amendment” to Indictment
The defendant asserts that the trial court impermissibly amended the indictments contained in counts five and six and therefore the defendant’s convictions on these counts should be reversed and these indictments [558]*558should be dismissed. Count five13 initially charged the defendant both with intentional and felony murder of guard Edward Cody. Because the indictment did not contain an allegation that the defendant intended to cause Cody’s death, at an earlier stage of the proceedings, that part of the indictment was dismissed. Count six14 charged the defendant both with intentional and felony murder of William West. The jury found the defendant guilty of felony murder in counts five and six and not guilty of intentional murder in count six.
[559]*559General Statutes § 53a-54a15 in subsection (a) defines intentional murder. Section 53a-54c16 defines felony murder. Subsection (c) of § 53a-54a prescribes the punishment for both intentional and felony murder. It is, therefore, proper in an indictment for felony murder to allege violation of §§ 53a-54c and 53a-54a (c). See State v. Derrico, 181 Conn. 151, 153, 434 A.2d 356, cert, denied, 449 U.S. 1064, 101 S. Ct. 789, 66 L. Ed. [560]*5602d 607 (1980). The fact that the indictment alleged violation of § 53a-54a without specifically alluding to subsection (c) is of no consequence. “The language of an indictment serves two primary purposes: it informs the accused of the nature of the crime charged and it acts as a bar to future criminal proceedings on the same cause.” State v. Cofone, 164 Conn. 162, 167, 319 A.2d 381 (1972). An indictment charging an accused with intentional and felony murder of a particular victim charges a single offense, committed conjunctively in two different ways. Id., 166; State v. Edwards, 163 Conn. 527, 532, 316 A.2d 387 (1972). Counts five and six initially charged both intentional and felony murder. Under such counts the jury may convict if it finds that the murder was committed in either or both of the ways alleged. When the first part of count five was dismissed the second part charging the defendant with felony murder remained. The defendant was on proper notice of the offense with which he was charged.
The court quite properly instructed the jury to disregard § 53a-54a in its consideration of the felony murder indictments. The jury is concerned only with the elements of the crime charged. The defendant does not claim nor is there a basis for a claim that the jury was not properly instructed on the elements of the crime of felony murder. The penalty provisions of § 53a-54a were not matters for the jury’s consideration since it is not the jury’s duty to pass upon the punishment of the accused. State v. Wade, 96 Conn. 238, 243, 113 A. 458 (1921); State v. Main, 75 Conn. 55, 63, 52 A. 257 (1902).
IV
Prosecutor’s Summation
During the opening summation, Walter Scanlon, chief assistant state’s attorney, reading from a prepared text, made a number of disparaging comments about the [561]*561defendant and his codefendant, characterizing them, inter alia, as “murderous fiends,” “rats,” “utterly merciless killers” and “inhumane, unfeeling and reprehensible creatures.” The defendant’s repeated objections to these remarks on the defendant’s character were overruled and his requests for curative instructions were denied. At the conclusion of this opening summation, the defendant moved in the alternative for a mistrial or for the court to strike Scanlon’s entire summation or those portions which the defendant recited on the record,17 together with “the strongest possible instructions to the jury to disregard all such comments.” The trial court denied the motion but at the conclusion of its instructions to the jury stated the following: “I specifically charge you not to be inflamed by the passionate nature of State’s Attorney Scanlon’s argument or by his repeated personal comments on the defendants. The defendants’ character is not in issue. With respect to Mr. Scanlon’s argument before you, I specifically charge you that you are not to consider any personal observations of his as to the guilt or innocence of the defendants, or as to the credibility of any witness.”18
[562]*562In State v. Carr, 172 Conn. 458, 470, 374 A.2d 1107 (1977), we stated “that a prosecutor should avoid arguments which are calculated to influence the passions or prejudices of the jury, or which would have the effect of diverting the jury’s attention from their duty to decide the case on the evidence.” Measured against this standard Scanlon’s argument was improper. “It is no part of a district attorney’s duty, and it is not his right, to stigmatize a defendant. He has a right to argue that the evidence proves the defendant guilty as charged in the indictment, but for the district attorney himself to characterize the defendant as ‘a cold-blooded killer’ is something quite different. No man on trial for murder can be officially characterized as a murderer or as ‘a cold-blooded killer,’ until he is adjudged guilty of murder or pleads guilty to that charge.” (Emphasis in original.) Commonwealth v. Capalla, 322 Pa. 200, 204, 185 A. 203 (1936).
But that is not the end of the inquiry. Because the right implicated is the defendant’s due process right to a fair trial, we proceed next to an examination of the remarks to determine their likely impact. “[T]he touchstone of due process analysis in cases of alleged prosecutorial misconduct is the fairness of the trial, not the culpability of the prosecutor.” Smith v. Phillips, 455 U.S. 209, 219, 102 S. Ct. 940, 71 L. Ed. 2d 78 (1982); State v. Cosgrove, 186 Conn. 476, 489, 442 A.2d 1320 (1982). “The question before us on this appeal is not, primarily, whether the remarks in question were proper or improper, but it is whether the action of the trial court in refusing to grant a new trial on account of them, in the exercise of its discretion, so far exceeded or abused the discretion committed to it in a matter of this kind as to warrant us in granting a new trial.” State v. Laudano, 74 Conn. 638, 646, 51 A. 860 (1902). The question then is whether the remarks of the prosecution were so egregious that no curative instruction [563]*563could remove their prejudicial impact. If the characterization of the defendant consisted of an isolated remark we would conclude that the potential prejudicial impact on the jury could be obviated by a curative instruction. But here, where the prosecutor persisted in his invective and the defendant’s repeated objections were overruled, the jury could only be left with the impression that the comments were proper. To suggest that an instruction would neutralize the prejudicial impact is to defy reality. “Not even appellate judges can be so naive as really to believe that all twelve jurors succeeded in performing what Judge L. Hand aptly called ‘a mental gymnastic which is beyond, not only their powers, but anybody’s else.’ Nash v. United States, 54 F.2d 1006, 1007 (2d Cir. 1932).” United States v. Bozza, 365 F.2d 206, 215 (2d Cir. 1966).
When a defendant has been convicted of committing a number of heinous crimes on a record that does not permit serious doubt of his guilt, it is painful to reverse his conviction. Our constitution, however, does not condition constitutional rights on guilt or innocence. “Indeed, it is ‘well established that serious prosecutorial misconduct, regardless of the prosecutor’s intentions, may so pollute a criminal prosecution as to require a new trial, even without regard to the prejudice to the defendant.’ State v. Hafner, [168 Conn. 230,] 251, [362 A.2d 925, cert. denied, 423 U.S. 851, 96 S. Ct. 95, 46 L. Ed. 2d 74 (1975)]. Crucial considerations in appellate adjudication of such questions are not only the need, where demonstrated, to discipline prosecutors where reprehensible conduct is present but to assure ultimate fairness to the defendant. State v. Hafner, supra, 252; see Smith v. Phillips, 455 U.S. 209, 219, 102 S. Ct. 940, 71 L. Ed. 2d 78 (1982).” State v. Binet, 192 Conn. 618, 629, 473 A.2d 1200 (1984). Each case necessarily depends on its own facts and circumstances. If the challenged remarks occurred in the heat of a sum[564]*564mation, if they were only isolated or brief episodes in a lengthy summation and if they were followed by a curative instruction, the weight of the evidence against the defendant could be a significant factor in upholding his conviction. See annot., 40 L. Ed. 2d 886, Due Process-Prosecutor’s Statements. But here the prosecutor’s prepared remarks were deliberate, facially improper, persistent and pronounced. In these circumstances the prosecutor’s assertion that because of the strong evidence of the defendant’s guilt his remarks should be found harmless has a hollow ring. “[A]ppeals to passion and prejudice may so poison the minds of jurors even in a strong case that an accused may be deprived of a fair trial.” United States v. Socony-Vacuum Oil Co., 310 U.S. 150, 240, 60 S. Ct. 811, 84 L. Ed. 1129, reh. denied, 310 U.S. 658, 60 S. Ct. 1091, 84 L. Ed. 1421 (1940). The prosecutor cannot pollute the waters and then claim that we should ignore his actions because the fish are not worth saving. Given the egregious nature of the prosecutor’s remarks, a failure on our part to reverse the defendant’s conviction would suggest that in a strong case the defendant is not entitled to a fair trial and therefore anything goes. We conclude that in his opening summation the prosecutor’s character assassination of the defendant so tainted the trial as to deny the defendant due process of law.
Article first, § 8 of the Connecticut constitution provides that “[n]o person shall be . . . deprived of . . . liberty . . . without due process of law . . . .’’It is the prosecutor’s duty to ensure that a defendant’s conviction comports with this provision. As we stated in State v. Ferrone, 96 Conn. 160, 168-69, 113 A. 452 (1921) “[b]y reason of his office, [the prosecutor] usually exercises great influence upon jurors. His conduct and language in the trial of cases in which human life or liberty are at stake should be forceful, but fair, because [565]*565he represents the public interest, which demands no victim and asks no conviction through the aid of passion, prejudice, or resentment.” Because the prosecutor’s remarks denied the defendant a fair trial in violation of both the federal and state constitutions, the trial court erred not only in overruling the defendant’s objections to the prosecutor’s improper remarks but also in denying the defendant’s motion for a new trial.
V
Consecutive Sentences — Felony Murder
The defendant was convicted of both the intentional and the felony murder of Leslie Clark and of the felony murders of Edward Cody and William West. He received separate sentences for the murder of each guard, the term (twenty-five years to life) of each sentence to be served consecutively. The defendant challenges the legality of these consecutive sentences both as a matter of statutory construction and as a violation of the double jeopardy clause of the fifth amendment to the United States constitution. We do not agree with the defendant’s position in either respect.
Felony murder is a crime against the person. General Statutes § 53a-54c, which proscribes felony murder, provides in pertinent part: “A person is guilty of murder when, acting either alone or with one or more persons, he commits . . . robbery . . . and, in the course of and in furtherance of such crime ... he, or another participant . . . causes the death of a person other than one of the participants . . . .” Death caused in the course of and in furtherance of the underlying felony is an essential element of the crime of felony murder. State v. MacFarlane, 188 Conn. 542, 550, 450 A.2d 374 (1982); State v. Morin, 180 Conn. 599, 605, 430 A.2d 1297 (1980).
The statute refers to the death of “a person” in the singular. A fundamental purpose of the criminal law is to protect individual citizens from the criminal con[566]*566duct of another. People are neither fungible nor amorphous. Where crimes against persons are involved, a separate interest of society has been invaded for each violation. Therefore when two or more persons are the victims of a single episode there are as many offenses as there are victims. State v. Gunter, 132 Ariz. 64, 70, 643 P.2d 1034 (1982); State v. Irvin, 603 S.W.2d 121 (Tenn. 1980); Vigil v. State, 563 P.2d 1344, 1351 (Wyo. 1977). As the Wyoming Court so aptly stated in Vigil, (p. 1351): “It must be noted that ‘any human being’ is in the singular and there is no indication that the defendant can get a bargain rate if he assaults a group of human beings.”
There are no double jeopardy obstacles to our construction of the felony murder statute. The double jeopardy clause of the United States constitution protects against multiple punishments for the same offense. North Carolina v. Pearce, 395 U.S. 711, 717, 89 S. Ct. 2072, 23 L. Ed. 2d 656 (1969). “With respect to cumulative sentences imposed in a single trial, the Double Jeopardy Clause does no more than prevent the sentencing court from prescribing greater punishment than the legislature intended.” Missouri v. Hunter, 459 U.S. 359, 366, 103 S. Ct. 673, 74 L. Ed. 2d 535 (1983). It does not prevent either multiple convictions or multiple punishment for multiple offenses. State v. James, 631 P.2d 854, 855-56 (Utah 1981).
There is error, the judgment is set aside and a new trial is ordered.
In this opinion Peters, Grillo and Ment, Js., concurred.
