Peters, C. J.
The principal issues on this appeal are the validity of the information charging the defendant, Jeffrey Rollinson, with having committed the crime of murder in violation of General Statutes § 53a-54a,1 and the admissibility at his trial of inculpatory statements that he made while he was a patient in a hospital alcohol detoxification unit. The trial court, after a jury verdict of guilty as charged, sentenced the defendant to [643]*643incarceration for a term of twenty-five years. The defendant has appealed on multiple grounds. We find no error.
The jury could properly have found the following facts. On the morning of March 18, 1983, the body of Hazel Clinkard was found in the bedroom of her Bethel home. The victim had been brutally beaten and repeatedly stabbed. Near the body, the police found a bloodstained warm-up jacket worn by the assailant during the attack. This jacket belonged to the defendant, and it had been seen in the car the defendant had been driving the previous day.
During much of that previous day, March 17, the defendant had been drinking at various bars with Raymond Pannozzo and Jerry Lee Forker, both of whom lived in the victim’s home. Pannozzo had told the defendant that the victim kept money in her bedroom. Pannozzo and Forker had invited the defendant to spend the night at the Clinkard home and the front door was, by agreement, left unlocked for the defendant when Pannozzo returned home alone. Pannozzo exchanged a few words with the victim in the early hours of March 18 and discovered her body later that morning.
On March 23, 1983, the defendant voluntarily admitted himself to the alcohol detoxification unit at Danbury Hospital. While there, he made a number of incriminating statements to members of the staff and to other patients. Upon his discharge, he went, in mid-April, to search a brook into which he thought he might have thrown a paring knife that might have been used in the slaying of the victim. A police scuba diver subsequently discovered such a knife in that location, and the knife was identified at trial as resembling one that was missing from the victim’s home.
[644]*644In this appeal from his conviction of murder, the defendant has raised ten issues that can conveniently be considered in four groupings. He maintains that the trial court erred: (1) in sustaining the validity of the information by which he was charged; (2) in two evidentiary rulings permitting the jury to hear incriminatory and prejudicial statements; (3) in improperly instructing the jury on reasonable doubt, motive and intent; and (4) in denying his posttrial motion for acquittal. We find no reversible error with regard to any of the defendant’s claims.
I
The defendant has launched a twofold attack on the validity of the information by which he was charged with the crime of murder. Each of these claims of invalidity arises out of the 1983 enactment of General Statutes § 54-46a.2 This statute was enacted to implement [645]*645the provisions of article XVII of the amendments to the Connecticut constitution, which substituted a probable cause hearing for the grand jury indictment formerly required before a person could be held to answer for a crime punishable by death or life imprisonment. Conn. Const., amend. XVII.3 The defendant maintains that: (1) § 54-46a cannot be applied in his case without violating the prohibition against ex post facto laws contained in article one, § 10, of the United States constitution;4 and (2) § 54-46a cannot be applied in any case [646]*646without violating the prohibition against the separation of powers contained in article second of the Connecticut constitution.5 These claims must be addressed separately.
A
The rules of law that underlie the defendant’s claim under the United States constitution are well established. The prohibition of ex post facto laws forbids the enactment of “any law ‘which imposes a punishment for an act which was not punishable at the time it was committed; or imposes additional punishment to that then prescribed.’ Cummings v. Missouri, 4 Wall. 277, 325-26, 18 L. Ed. 356 (1867).” Weaver v. Graham, 450 U.S. 24, 28, 101 S. Ct. 960, 67 L. Ed. 2d 17 (1981); see also W. LaFave & A. Scott, Criminal Law (1972) § 12; 2 R. Rotunda, J. Nowak & J. Young, Treatise on Constitutional Law: Substance and Procedure (1986) § 15.9 (b); L. Tribe, American Constitutional Law (1978) §§ 10-2, 10-3. Under the applicable federal cases, “two critical elements must be present for a criminal or penal law to be ex post facto: it must be retrospective, that is, it must apply to events occurring before its enactment, and it must disadvantage the offender affected by it.” (Emphasis in original.) Weaver v. Graham, supra, 29.
Retroactivity, the first of these elements, is not an issue in this case. The crime of murder that the defendant was alleged to have committed occurred on March 18, 1983. Although the constitutional amendment abolishing the indicting grand jury had been approved by the voters the previous fall, § 54-46a, the statute that was required to implement that amendment, did not take [647]*647effect until May 26, 1983. Section 54-46a repealed the prior statutory provision for grand jury indictments contained in General Statutes § 54-45 and prescribed the procedures by which probable cause hearings would be conducted. We held, in State v. Sanabria, 192 Conn. 671, 691, 474 A.2d 760 (1984), that “that portion of the [constitutional] amendment establishing probable cause hearings did not take effect until the enabling legislation took effect on May 26, 1983.” On its effective date, “all persons then being held for crimes punishable by death or life imprisonment, who had not yet been indicted by grand jury became entitled to a probable cause hearing before their cases went to trial, regardless of the dates on which they were arrested or charged by information.” (Emphasis in original.) Id., 699. The defendant was charged with murder on July 13,1984, and was, on September 6,1984, afforded a hearing in probable cause pursuant to § 54-46a. It is therefore undisputed that, although the defendant was charged with the commission of a crime that antedated the effective date of § 54-46a, his prosecution has been governed retrospectively by the new procedures mandated by that statute.
The crucial question is that posed by the second element of the ex post facto test: does the substitution of a probable cause hearing for a grand jury indictment unconstitutionally “disadvantage the offender affected by it?”6 The defendant maintains that this question [648]*648should be answered in the affirmative because of several salient differences between grand jury proceedings and probable cause hearings: (1) the vesting of decision-making authority in a grand jury consisting of peer group representatives of the community at large in contrast to the determination of probable cause by a single judge; (2) the absence of counsel for the state, and for the defendant, at grand jury proceedings, in contrast to their affirmative role in probable cause hearings; (3) the grand jury’s discretion to gather information without regard to the formal rules of evidence, in contrast to the evidentiary rules that govern probable cause hearings; and (4) the confidentiality afforded by a grand jury proceeding, in contrast to the public nature of a probable cause hearing. The defendant argues that these distinctions present significant disadvantages that are not offset by his right, at his probable cause hearing, to have counsel present, to be informed of the basis of the charge against him and to present rebuttal evidence. We are unpersuaded.
The changes embodied in amendment seventeen to article first, § 8, of the Connecticut constitution, as implemented by § 54-46a, represent the collective judgment of the legislature and of the voters that indicting grand juries did not provide adequate safeguards for those accused of having committed serious crimes. As we noted in State v. Mitchell, 200 Conn. 323, 326-27, 512 A.2d 140 (1986), “ [although originally conceived as a shielding device to protect individuals from unfounded prosecutions; State v. Menillo, 159 Conn. 264, 275, 268 A.2d 667 (1970); the grand jury system came to be widely criticized for its secret operation and its ex parte nature. See Spinella, Conn. Crim. Proc. (1985) pp. 272-73; Berdon, ‘Connecticut Grand Juries: The Case for Reform,’ 54 Conn. B.J. 8, 9-16 (1980); Goldstein, ‘The State and the Accused: Balance of Advantage in Criminal Procedure,’ 69 Yale L. J. 1165, 1171 (1960).” [649]*649The grand jury system precluded the accused person from effective participation in its processes and precluded judicial review of the evidentiary basis of any indictment that the grand jury might return. State v. Mitchell, supra, 327, and cases there cited. These defects in the grand jury system do not become virtues simply because the defendant has labeled them as such. The advantages of an adversarial evidentiary hearing, with the assistance of counsel, are similarly not to be deprecated just because a hearing in probable cause is necessarily more limited in scope than a full trial on the merits. A defendant against whom a grand jury returns a true bill is afforded no more privacy than a defendant who is held for trial after a hearing in probable cause. For all of these reasons, the substitution of a fair and open hearing by a judge familiar with the legal requirements of probable cause does not place an accused in a position more disadvantageous than that offered by a secret indictment returned by a jury of his peers.
The prohibition against ex post facto laws does not interdict the retrospective application of every change in the laws governing the criminal justice system. We have found no constitutional impediment in changes in the number of peremptory challenges available to the state; State v. Hoyt, 47 Conn. 518, 532-33 (1880); or in the number of persons composing a jury. State v. Maresca, 173 Conn. 450, 451-54, 377 A.2d 1330 (1977). We conclude that the change from indictment to information similarly did not so disadvantage the defendant as to require the dismissal of the charges against him. Accord Hubbard v. State, 411 So. 2d 1312, 1313 (Fla. App. 1981); People v. Tibbs, 46 Ill. App. 3d 310, 311-12, 360 N.E.2d 993 (1977); State v. Sepulvado, 342 So. 2d 630, 635-36 (La. 1977); State v. Kyle, 166 Mo. 287, 303-306, 65 S.W. 763 (1901); People ex rel. Pincus v. Adams, 274 N.Y. 447, 454-57, 9 N.E.2d 46 [650]*650(1937); Wells v. Maxwell, 174 Ohio St. 198, 200, 188 N.E.2d 160 (1963); Lybarger v. State, 2 Wash. 552, 554-61, 27 P. 449 (1891); contra Putty v. United States, 220 F.2d 473, 476-77 (9th Cir. 1955).
B
The defendant’s alternate attack on the validity of the information by which he was charged rests on a premise derived from state constitutional law. He maintains that the legislative enactment of § 54-46a is an unconstitutional encroachment on the powers assigned to the judiciary by virtue of the separation of powers provisions of our state constitution. Conn. Const., arts. II and V, § l.7 This argument is based on the fact that it was not until October 1, 1984, a date subsequent to the defendant’s probable cause hearing, that our rules of practice were amended to delete rules for indicting grand juries and to insert rules to govern hearings in probable cause.8 The defendant contends, therefore, that at the time when he was arrested, arraigned and brought before the court, there existed an unconstitutional conflict between the statutory provisions of § 54-46a and the applicable rules of the Practice Book.
The scope of the rule-making authority conferred upon the judiciary is ordinarily determined by the distinction between procedural and substantive law. As a general proposition, the General Assembly lacks the power to enact rules governing procedure, and the [651]*651Superior Court lacks the power to promulgate rules governing substantive rights and remedies. State v. King, 187 Conn. 292, 297-98, 445 A.2d 901 (1982); Steadwell v. Warden, 186 Conn. 153, 162-63, 439 A.2d 1078 (1982); Adams v. Rubinow, 157 Conn. 150, 152-58, 251 A.2d 49 (1968). However uncertain the line between procedure and substance sometimes may be, there is no room for doubt with regard to § 54-46a. We expressly held, in State v. Sanabria, supra, 690, that the implementing procedures contained in § 54-46a were “constituent parts” of the substantive rights created by amendment seventeen. That constitutional amendment, by its own terms, conferred upon the legislature, and not upon the courts, the authority to fashion “procedures prescribed by law” for hearings to determine probable cause. In these circumstances, the validity of § 54-46a is not subject to constitutional attack as a violation of separation of powers. Accordingly, we find no error in the trial court’s refusal to dismiss the information charging the defendant with the crime of murder.
II
The defendant claims that his conviction must be overturned because of two allegedly erroneous evidentiary rulings by the trial court. The defendant maintains that the trial court erred in permitting the jury to hear: (1) the incriminating statements that he made while he was a patient in the alcohol detoxification unit of Danbury Hospital; and (2) the audio tape of Raymond Pannozzo’s interview by police detectives at a time when Pannozzo was suspected of having killed the victim. These claims of error invoke unrelated principles of law and thus warrant separate discussion, although we conclude that neither of them warrants reversal of the defendant’s conviction.
[652]*652A
The defendant’s first evidentiary claim concerns the trial court’s denial of his motion in limine to suppress a number of highly incriminating statements that he made to staff and fellow patients on March 23 and 24, 1983, after he had been admitted voluntarily to the Dan-bury Hospital detoxification unit. The defendant told Dorothy Bauer, a sitter assigned to him by the nurses’ registry, that, in connection with “a death in Bethel,” he had done “something bad,” that “no one would believe me.” In a conversation with the unit’s head nurse, Margarita Barab, the defendant admitted that he had gone to the home of an elderly woman who was the landlady of one of his drinking friends, and had there struggled to obtain money from her. He acknowledged that he had violently assaulted the woman and expressed concern over blood on the jacket that he had worn on that occasion. Speaking with Dr. John Melbourne, the head of the detoxification unit, the defendant mentioned “an old person in Bethel,” and said, “I’m no good. I don’t deserve to live. I should die,” while also indicating uncertainty about whether he had “done it.” In a group therapy session, the defendant related to another patient that “he had gone to a house in Bethel, and that a lady had surprised him and was hollering at him, and he hit her and kept hitting her.” He also spoke of searching for a knife he might have thrown “in the brook.”
Conceding that none of these statements falls expressly within the statutory privilege of confidential communications with a psychiatrist or a psychologist; General Statutes § 52-146c;9 the defendant maintains that they should nonetheless have been suppressed for [653]*653a number of statutory and other reasons. His principal claim of privilege is that the statements were protected by the provisions for confidentiality of records in the federal Comprehensive Alcohol Abuse and Alcoholism Prevention, Treatment, and Rehabilitation Act of 1970; 42 U.S.C. § 290dd-3;10 which is incorporated into our [654]*654statutes by General Statutes § 17-155bb (b).11 We find no error in the trial court’s consideration of the applicability of these statutes.
The Comprehensive Alcohol Abuse and Alcoholism Prevention, Treatment, and Rehabilitation Act establishes a conditional and not an absolute right of nondisclosure of the records12 of patients involved in alcohol treatment. The federal statute permits a court to order disclosure for good cause shown, after weighing “the [655]*655public interest and the need for disclosure against the injury to the patient, to the physician-patient relationship, and to the treatment services.” 42 U.S.C. § 290dd-3 (b) (2) (C). Applicable federal regulations indicate that the public interest in disclosure may outweigh possible damage to the treatment relationship when disclosure of material information not elsewhere available is sought for the purpose of a criminal prosecution for an extremely serious crime like homicide. 42 C.F.R. § 2.65.13 The state gave notice to the defendant and the hospital of its intention to introduce the records at trial, in accordance with the federal statute and regulations. After a hearing on the motion in limine, in [656]*656which both the state and the defendant were given an opportunity to present argument, the court exercised its discretion to order disclosure. The defendant does not quarrel with the process by which this decision was reached, but maintains that the court should have concluded that the harm that disclosure would cause to him and to the treatment program outweighed the benefits of disclosure.
The privilege which the defendant seeks to attach to his statements at the detoxification unit is a statutory privilege and not a constitutional one. Under the circumstances, the scope of our review of the ruling of the trial court is limited. The trial court’s ruling is analogous to the exercise of discretion that is required whenever the state seeks to introduce a defendant’s prior criminal behavior into evidence. When a trial court, recognizing the general rule excluding such evidence, determines nonetheless that in a particular case the probative value of prior crimes evidence outweighs its prejudicial effect, we reverse such a decision “only where abuse of discretion is manifest or where an injustice appears to have been done. State v. Johnson, 190 Conn. 541, 549, 461 A.2d 981 (1983).” State v. Smith, 198 Conn. 147, 157, 502 A.2d 874 (1985); State v. Morowitz, 200 Conn. 440, 446, 512 A.2d 175 (1986). Applying that test in this case, we find no reason to overturn the trial court’s denial of the defendant’s motion in limine.
The defendant’s remaining arguments concerning the allegedly privileged status of his statements at the detoxification unit do not warrant any extended discussion. He seeks to invoke the nondisclosure provisions of General Statutes § 19a-383,14 but that statute [657]*657is limited to information elicited in the course of treatment for drug dependence, and drug dependence is itself defined, by § 19a-381 (3), as involving the use of “a controlled drug as defined in section 21a-240.” Alcohol is expressly excluded from the definition of “controlled drugs” contained in § 21a-240 (8).15 In the absence of a common law privilege of nondisclosure of communications between a patient and a physician; State v. Hanna, 150 Conn. 457, 464, 191 A.2d 124 (1963); we are unpersuaded that it was a violation of the defendant’s constitutional rights to equal protection16 for the legislature to create a statutory privilege [658]*658that encompasses drug addiction but not alcohol addiction. It was entirely reasonable for the legislature to conclude, in the exercise of its police power, that the widespread problem of dependence on controlled drugs required remedial action. To implement its public purpose of providing state support for drug dependence treatment programs, the legislature might reasonably have determined that effective treatment programs had to encompass treatment incentives that would take into account the fact that possession of controlled drugs is ordinarily illegal. Thus, the legislature could rationally create a greater privilege of nondisclosure for the class of those involved in drug treatment programs than for those involved in alcohol treatment programs. The law of equal protection requires no more. See, e.g., Daily v. New Britain Machine Co., 200 Conn. 562, 577-80, 512 A.2d 893 (1986); Beccia v. Waterbury, 192 Conn. 127, 133-34, 470 A.2d 1202 (1984).
The defendant had no cognizable expectation of privilege under any of the other theories he has advanced. There is neither a claim nor a finding that those in whom he confided at the Danbury Hospital held themselves out to be psychologists or psychiatrists. There is therefore no privilege under General Statutes §§ 52-146c or 52-146d even if, as the defendant claims on appeal, he reasonably believed that the health professionals to whom he spoke were psychologists or psychiatrists.17 We have no reason to doubt the defendant’s assertion that the therapeutic atmosphere at the detoxification unit was conducive to communications which might not be made in other settings. We are unprepared, however, to recognize a constitutional or a common law right of privacy in such a situation. As discussed earlier, our federal and state statutes have established limited privileges for records of patients [659]*659involved in alcohol and drug treatment, which, as the trial court concluded, do not apply in the particular circumstances of this case. Finally, we reject the defendant’s argument that his statements at the hospital were admissions which the state failed to prove voluntary. Having been made in a noncustodial setting, the defendant’s incriminatory statements are admissible without a prior showing by the state that they were voluntarily made. See Colorado v. Connelly, 479 U.S. 157, 166-67, 107 S. Ct. 515, 93 L. Ed. 2d 473 (1986).
The defendant’s other evidentiary claim concerns the trial court’s denial of his objection to the playing of audio tapes of the police interrogation of Raymond Pannozzo. This evidentiary issue arose in the context of the defendant’s efforts to persuade the jury that it was Pannozzo who had killed the victim. After Pannozzo had testified for the state about his lack of involvement with the crime, the defendant cross-examined him extensively about a written confession that he had previously given to the police. As a part of this cross-examination, Pannozzo read his confession aloud to the jury.18 The state, on redirect examination, questioned Pannozzo about the circumstances leading to his confession. It offered the interrogation tapes into evidence in order to show Pannozzo’s state of mind when he confessed: his apparent confusion and memory lapses, his concern for his drinking problem, and his emotional and distraught behavior. Admitting the tapes for this limited purpose, over the defendant’s objection, the trial court immediately cautioned the jury that their contents were not proof of the truth of what had been said, and later repeated this caution in its instructions to the
[660]*660The defendant claims that the tape was inadmissible both because it was hearsay and because its limited probative value was outweighed by its prejudicial effect. We disagree. Offered to establish the context of the Pannozzo confession, the tape was not hearsay as its use was limited to proof of Pannozzo’s state of mind during his interview by the police. State v. Sharpe, 195 Conn. 651, 661-62, 491 A.2d 345 (1985); State v. Periere, 186 Conn. 599, 605-607, 442 A.2d 1345 (1982); State v. Packard, 184 Conn. 258, 274, 439 A.2d 983 (1981). This evidence was highly relevant to rebut the inference that the jury would otherwise have been likely to draw from the fact of Pannozzo’s confession, which was potentially very damaging to the state’s case. It was within the province of the trial court to determine whether, on balance, the probative value of this evidence outweighed its potentially prejudicial impact on the defendant. State v. Periere, supra, 607-608. We can discern no abuse of discretion in the trial court’s decision to admit this evidence in this case.
III
The defendant maintains that the trial court erred in its instructions to the jury when it: (1) included an inappropriate example of what is meant by reasonable doubt; (2) denied the defendant’s request to charge concerning motive; (3) permitted the jury to consider a possible sexual assault as relevant to the defendant’s intent to commit murder when the defendant had not been charged with sexual assault; and (4) failed to instruct the jury properly with regard to the relationship between intoxication and intent. These claims warrant only limited review. We find no error.
Turning first to the charge on reasonable doubt, we note that the defendant claims that the trial court improperly included an example of what might constitute reasonable doubt that was based on a hypotheti[661]*661cal case of robbery unrelated to the crime with which the defendant was charged.19 This claim of error has not been briefed in accordance with the requirements of the rules of practice, since neither the defendant’s brief nor his appendix contains a verbatim statement of the exception that he took at trial. Practice Book [662]*662§ 4065 (d) (2) (formerly § 3060F).20 The importance of this rule is highlighted by an examination of the exception as actually taken, which could fairly have been understood by the trial court as raising no issue other than possible confusion arising out of the court’s emphasis of what did not constitute reasonable doubt rather than out of what would so qualify. On this state of the record, although we continue to doubt the advisability of verbal elaboration of the meaning of reasonable doubt; State v. DelVecchio, 191 Conn. 412, 417-21, 464 A.2d 813 (1983); we are not persuaded that DelVecchio is controlling. Elsewhere in its instructions, the trial court repeatedly correctly instructed the jury about the state’s burden of proving each element of the crime beyond a reasonable doubt. Applying the standard of review appropriate under State v. Evans, 165 Conn. 61, 65, 327 A.2d 576 (1973), we therefore conclude that there was no reversible error in the trial court's effort to illuminate that construct through an illustration. See also State v. Simms, 201 Conn. 395, 419, 518 A.2d 35 (1986).
[663]*663The defendant’s second claim is that the trial court erred in its refusal of his request to charge on motive. This claim of error also is improperly briefed, because the defendant has nowhere reproduced “a verbatim statement of the relevant portions of the charge as requested and as given by the court and any relevant exceptions to the charge as given . . . .” Practice Book § 4065 (d) (1).21 In light of this total noncompliance with our rules of practice, we decline to entertain a plenary review of this issue. Weintraub v. Richard Dahn, Inc., 188 Conn. 570, 571-72, 452 A.2d 117 (1982); see also State v. Pass, 191 Conn. 604, 621, 469 A.2d 767 (1983). While evidence of motive may be desirable and important in determining the strength of the state’s case, such evidence is not a necessary element of the crime of murder. State v. Harris, 182 Conn. 220, 223-24, 438 A.2d 38 (1980); State v. Annunziato, 169 Conn. 517, 530, 363 A.2d 1011 (1975); W. LaFave & A. Scott, Criminal Law (1972) § 29, p. 204. Failure expressly to instruct on motive, in the absence of an appropriate request to charge, is therefore not a miscarriage of justice. State v. Annunziato, supra.
The defendant asserts, in his third claim of error, that the court’s instructions on intent incorrectly alluded to an uncharged sexual assault on the victim. Again we note that the defendant’s appellate brief lacks the verbatim statement of “relevant exceptions to the charge” that is required by Practice Book § 4065 (d) (2). [664]*664The trial court noted the evidence of a sexual assault in the course of its recital of the circumstances and the manner of the victim’s death.22 We fail to perceive how this recital could have misled the jury in this case in which the focus of the defense was not whether a crime had been committed but rather the identity of its perpetrator. Viewed as a whole, the trial court’s main and supplemental instructions adequately and accurately informed the jury of the elements of the crime that the state was required to prove in order to establish that the defendant was guilty as charged. State v. Simms, supra, 416; State v. Cobb, 199 Conn. 322, 326-30, 507 A.2d 457 (1986). The defendant was not deprived of a fair trial by this aspect of the instructions on intent.
The defendant’s fourth and final disagreement with the court’s instructions concerns the effect of intoxication on intent. The court informed the jury that a finding of intoxication would militate against a finding of criminal intent. The defendant concedes that, at the trial, he took no exception whatsoever to this aspect of the instructions. He relies therefore on review [665]*665under State v. Evans, supra, as a basis for his claim that the trial court erred in not specifically stating that it was the burden of the state to persuade the jury beyond a reasonable doubt that despite the defendant’s intoxication, he had the necessary specific intent to commit the crime of murder. Even though review under Evans is appropriate to consider whether there was constitutional error in the instructions on intent; State v. Stevenson, 198 Conn. 560, 567-72, 504 A.2d 1029 (1986); we find no such error in the instructions as given. Viewing the main and supplemental instructions on burden of proof and on intent in their entirety, we are persuaded that the jury could not have been misled about the scope of the state’s responsibility to establish, beyond a reasonable doubt, that the defendant specifically intended to kill the victim.
IV
In his last claim of error, the defendant maintains that the trial court should have granted his motion for acquittal on the ground that the evidence at trial was insufficient to support the jury verdict finding him guilty of murder. Although he does not question that the evidence established the commission of a homicide, he argues that the state did not prove, beyond a reasonable doubt, either his role in that crime or his specific intent to commit it. We agree with the state that the jury could have found the defendant’s guilt to have been proven beyond a reasonable doubt.
In accordance with well established principles, appellate analysis of a claim of insufficiency of the evidence requires us to undertake a twofold task. “We first review the evidence presented at the trial, construing it in the light most favorable to sustaining the jury’s verdict. We then determine whether, upon the facts thus established and the inferences reasonably drawn therefrom, the jury could reasonably have concluded [666]*666that the cumulative effect of the evidence established guilt beyond a reasonable doubt .... In this process of review, it does not diminish the probative force of the evidence that it consists, in whole or in part, of evidence that is circumstantial rather than direct.” State v. Sinclair, 197 Conn. 574, 576, 500 A.2d 539 (1985), and cases there cited.
Given the admissibility of the defendant’s incriminatory statements at the alcohol detoxification unit, there was ample evidence of his role in the murder of the victim. The jury could reasonably have concluded that the defendant had killed the victim in light of the evidence that he had access to her house, had entered the house in the middle of the night, and had left his bloody jacket in the bedroom where she had been murdered. The evidence of the specific intent necessary to convict the defendant of murder was, as usual, more circumstantial. The state adduced the following: the defendant knew that the victim kept money in her bedroom, disposed of a knife that might have been the murder weapon in a nearby brook, told the police inconsistent stories about the whereabouts of his jacket, and related many incriminating details to those to whom he spoke at the detoxification unit. From this evidence, the jury might reasonably have determined that, despite his drinking,23 the defendant retained the capacity to form a specific intent to commit the crime of murder with which he had been charged.
There is no error.
In this opinion the other justices concurred.
