SCHAUER, J.
In the year 1939 the defendant Wilson De La Roi was found guilty of murder in the first degree and was sentenced to imprisonment for life. In the pending action it has been found that such defendant, while serving his term of imprisonment at Folsom State Penitentiary, committed an assault with a deadly weapon (and with deadly effect) and with malice aforethought upon a fellow convict. The penalty for the latter offense is death (Pen. Code, §4500), and from the judgment imposing that penalty this appeal comes to us automatically by the provisions of section 1239 (b) of the Penal Code.
The defendant urges five grounds for reversal which he states as follows:
“I. His first contention is that the information does not state a public offense, and that the Court had no jurisdiction over the subject of the information. ... II. The evidence is insufficient in point of law to warrant the State of California in' putting this appellant to death. III. The venue was never established in this ease and consequently appellant is entitled to a new trial. IV. The Court erred [694]*694in stating to the jury at the conclusion of his instructions that they could not exercise their right to send out or to receive any communication. V. The Court erred in failing to instruct the jury that a verdict of guilty condemned the defendant to die.”
Factual Background
The evidence, both direct and circumstantial, amply supports the verdict of guilty, but it discloses also certain circumstances pertaining to the investigation of the affair by prison officials and the treatment of prisoners who were known or believed to possess information relative to the occurrence, which have caused us to scan every word of testimony and every incident of procedure with most scrupulous care, not only to test the assignments of error made by the defendant but to lend independently our critical scrutiny to that of his able counsel in a search for any prejudice which could indicate a miscarriage of justice. The nature of such circumstances and treatment of prospective witnesses is such that any error whatsoever in the trial proceedings, which could reasonably have prejudiced the defendant, would require a reversal. After such scanning of the record and consideration of the defendant’s arguments, we are satisfied, however, that only one of the points urged by the defendant—point IV above stated—shows error in any respect, and we are further satisfied that the error on that point could not, in the light of the other instructions, have prejudiced the defendant but must rather' have tended to favor him.
William Deal was the victim of defendant’s assault. On the 15th day of July, 1942, in broad daylight (between the hours of 1 and 2 p. m.), in the laundry building at Folsom prison, in the immediate or near presence of at least forty-five persons, including a trusty-guard and a prison official (the laundry superintendent), Deal was stabbed three times with a six-inch dagger, once in the right forearm, once in the left chest, and once in the left back near the waist. The wound in the right forearm was relatively superficial, as was that in the left chest. The one in the back made a deep penetration, severed a large vein, and caused death within a few minutes through abdominal hemorrhage. The wound in the left chest was not fatal because, although apparently directed at the heart, its force was somewhat spent and it was deflected by striking and penetrating a tin can which [695]*695was in the left breast pocket of the shirt which Deal was wearing. Further importance of the fact that Deal was wearing a shirt will appear later in this opinion.
When Deal was stabbed he screamed. According to the laundry superintendent (one of the few witnesses who was not a convict), it was “a very loud scream, or holler, such as a very unusual scream, it sounded as if someone was being actually murdered over and above the sound of the laundry. ...” Deal not only screamed, he ran, endeavoring to escape, the defendant pursuing and “stabbing at” him. The laundry superintendent came to the door of his office (a room within the laundry building), someone called to the defendant to “beat it,” and someone suggested to Deal that he sit down. The defendant walked out; Deal, having in his flight run into a dryer and fallen down, got up, walked to a table, sat down on it, and soon collapsed.
As previously mentioned, there was a convict guard, or trusty, stationed at the door of the laundry building, whose duty it was to permit no unauthorized person to pass through the door. The killer of Deal, with his weapon, apparently was permitted to leave the building unmolested and unrestrained. The guard at the door was not produced as a witness. Whether he was interrogated by prison officials does not appear. Even the identity of the guard is not revealed. Whether there was a record as to who was on duty at the time is not stated. The laundry superintendent testified, “Just as I came through the door [from his office into the main room of the laundry] . . . running toward the table where Deal, near where he had fallen, I observed this man because I was wondering why he had left the door open; it was open at the time and the fellows were coming and going. ...” It does not appear that any order to close the door was given. Seemingly no witness who presumably knew the identity of the convict guard was willing to reveal it. Illustrative of the apparent attitude of all of the witnesses who were interrogated on that subject is the testimony of James Allen, one of the leading witnesses for the prosecution.
“Q. Isn’t there usually a convict guard at that door? A. Yes, there is, but Mr. Roosevelt [the laundry superintendent] was in his office at the time that happened, and that time the door was open.
“Q. Isn’t there usually a prisoner who acts as guard at that door? A. That is one thing I wouldn’t say, because I was attending to my business.
[696]*696“Q. You wouldn’t say then there is or there is not a prisoner who stands guard at that particular door and lets people in and out? A. Yes, there is, yes, but I never seen him at that time. I couldn’t say.
“Q. Your recollection now is that you don’t remember whether there was a prisoner guard there or not, that is, a convict guard? A. I wouldn’t say that, because I didn’t see any—I wouldn’t say that.
“Q. Do you know who the convict guard was at that door in the forenoon? A. No, I don’t. I don’t remember that. ’ ’
It appears that clothing issued to prisoners was stamped with a number identifying it as belonging to the prisoner to whom it was issued. Whether this was required to be done as an incident of issue or only upon its being sent to the laundry does not appear. It is significant here because the dagger identified as the lethal weapon was found in a trash can on the prison grounds wrapped in a pair of trousers. The dagger was not examined for fingerprints and, so far as appears, the trousers were not examined for an identification mark. It does not appear whether any effort was made to ascertain the identity of the owner of the trousers or whether the trousers were marked with an identifying number. The record is also silent as to the source of manufacture of the dagger and as to how it came into the possession of an inmate of the prison. During the appreciable period of time which elapsed between the stabbing of Deal and his lapse into unconsciousness through loss of blood, no one appears to have asked him the name of Ms assailant.
Coupled to the above related circumstances are the added facts that all of the witnesses who identify defendant as the perpetrator of the crime are themselves recidivists and in the furnishing of information or the giving of testimony they were faced with a problem which involved personal interest. It appears that conditions in the prison were such that it was unsafe for any prisoner who had testified or given information to the prison officials against a fellow convict to be left in the main yard of the prison. Accordingly it was the practice to protect such prisoners by giving them more favorable working or living quarters, outside the main yard. This practice was followed as to the principal prosecution witnesses. Also having a bearing upon the interest of witnesses, it appears that those prisoners who were deemed [697]*697by the prison officials to have been concerned in the commission, or in protecting the perpetrator, of the crime here involved, were placed in xsolitary confinement shortly after the assault upon Deal and were kept there until the time of trial. This treatment was applied to several defense witnesses. Fairness to the defendant demands that we consider the points urged by him in the light of the circumstances' related, and accordingly we so consider them, and in the order presented by defendant.
The Lam Points Presented
1. The Information States a Public Offense. Defendant contends that the information upon which he is prosecuted fails to state a public offense in that it does not describe the deadly weapon used and hence it cannot be ascertained “by what means of force the assault charged was committed.” The information alleges that “the said Wilson De La Roi on the 15th day of July, A. D. 1942, in the said County of Sacramento, in the said State of California, . . . being then and there a person undergoing a life sentence in . . . the State Prison at Folsom, did then and there willfully, unlawfully and feloniously and with malice aforethought commit an assault upon the person of William Deal with a deadly weapon or instrument and ’by means of force likely to produce great bodily injury. ...” Defendant relies upon statements in People v. Perales (1904), 141 Cal. 581 [75 P. 170]. That case was decided in 1904, long prior to the amendments of 1927 and 1929 of section 952 of the Penal Code, and no longer states the applicable rule of pleading in this state. (People v. Mitchell (1940), 40 Cal.App.2d 204, 209 [104 P.2d 545].) The section as amended expressly provides that an offense may be charged “in the words of the enactment describing the offense or declaring the matter to be a public offense, or in any words sufficient to give the accused notice of the offense of which he is accused.” The information fully meets the requirements of the present statute.
2. The Evidence Supports the Verdict. Medical testimony establishes that William Deal, one of defendant’s fellow inmates of Folsom State Penitentiary, died on July 15, 1942, from abdominal hemorrhage resulting from the severance of a large vein below the heart occasioned by a stab wound inflicted on the victim’s back. The assault occurred in the prison laundry which occupies a building 92.5 feet [698]*698long by 48.5 feet wide situated within the prison grounds. Three eyewitnesses testified to seeing defendant with a knife in his hand actually engaged in stabbing or “stabbing at” or “cutting” the decedent. Other witnesses testified to seeing the defendant enter or leave the laundry at about the time of the assault. Two witnesses testified that after defendant came out of the laundry he placed something in a trash can on the outer grounds. Later, a dagger having a blade approximately six inches long and a pair of trousers in which it had been concealed, were recovered from the trash can. Another witness asserted that on the day preceding the assault he overheard defendant telling Deal that “he wanted his stuff [tobacco, which was used as a medium of exchange] and he didn’t want no if or and about it.” This witness added that a few hours before his death Deal had arranged to borrow from him (the witness) seventy sacks of “weed” with which to pay his debt to defendant. Weak and seemingly illogical as is this evidence of motive—the death of the debtor would surely in this case obviate any chance for collection of the debt—it may, nevertheless, reveal a basis sufficient to have roused the unbridled emotions of this defendant.
Defendant took the stand in his own defense and denied making the assault. He stated that he and the deceased were the best of friends (that they had been seen together often is corroborated by several witnesses) and that no debt existed between them. By his testimony defendant placed himself out in the yard at “the back gate,” about 435 feet —the most remote point in the main yard—from the laundry, at the time of the assault. Certain inmates, called as witnesses by the defense, corroborated to some extent defendant’s narration of events. Three of them agreed on one point: that at the time of the commission of the assault the defendant was at or near “the back gate.” But their stories do not withstand careful analysis. One defense witness, Calvin Hanson, who admitted convictions for first degree robbery and for first degree burglary, testified that he saw Allen, a prosecution witness, follow Deal into the shower room, that he heard Deal yell, and that Allen then reappeared holding a knife and with “blood on his hands . . . dripping down, ’ ’ and that Deal did not reappear. This latter testimony not only was not corroborated by any other witness, but is thoroughly discredited by certain circumstances and other testimony. The witness insisted that Deal was not [699]*699wearing any shirt, “he was stripped to the waist,” whereas it is well nigh indisputably established by other evidence that Deal was wearing a shirt and that a tin can in the left breast pocket of the shirt, through which one knife thrust passed, contributed to prevent that blow from being fatal. Further discrediting circumstances are the facts that this witness had never told this story to anyone—not even to counsel for the defense—prior to telling it on the witness stand, and that his story left the fatally wounded Deal out of sight in the shower bath, whereas every other witness to the scene of the actual stabbing, including the laundry superintendent, placed Deal in plain sight in the main laundry room. It is difficult to conceive how a witness could be more completely discredited than was this one.
Other witnesses, besides the defendant, who testified for the defense, include Eddie Walker, the defendant’s cellmate, who admitted convictions for kidnaping, robbery, burglary, and escape from custody of an officer; John De La Roi (brother of defendant), who admitted convictions for burglary, first degree, burglary, second degree, and grand theft, and James Morgan, who admitted convictions for burglary, robbery of the first degree, and another robbery and kidnaping.
Eddie Walker, as previously mentioned, was defendant’s cellmate at the time the offense was committed. His testimony, much more closely than that of any other witness, comports with that given by defendant. It is to be noted that the evidence for the prosecution tends to an appreciable extent to connect Walker with the defendant in the commission of the offense charged. Walker’s testimony was to the effect that Deal, the defendant, and Walker, were the “best of friends,” that no debt could exist among them, and that at the time of the assault the defendant was “down to the back gate”—that farthermost point in the main yard from the laundry building — talking with a trusty. The trusty, called as a witness, did not corroborate this testimony.
John De La Roi, defendant’s brother, testified in substance that the defendant had played a game of handball with him “early in the afternoon” on July 15, and, like Walker, said that at the time of the assault the defendant was “down at the back gate” talking to a trusty. He also said that shortly before the stabbing he, the witness, “got through playing handball” and, being thirsty, went to a [700]*700point near the laundry to get a drink from a hydrant, where, through a window, he observed someone whom he did not recognize stabbing the decedent. The witness Morgan testified that he and the witness John De La Roi played handball on the day of the assault, with the defendant Wilson De La Roi keeping tally, but he differed materially from his co-witness John De La Roi in that according to Morgan the handball game “was probably half over, when I heard someone scream. . . . We stopped the game and walked over to see what was happening, Johnny De La Roi and I. . . .” Obviously if Morgan was telling the truth then John De La Roi was not near a window of the laundry looking in, when the assault occurred. About the only thing in which he agreed with John De La Roi was in placing the defendant near the back gate at the crucial time. He also said that the defendant engaged in playing handball with his brother that afternoon, but the defendant himself denied that he played handball on the day Deal was killed. Morgan likewise differed with the defendant in that Morgan testified that the defendant returned to the handball game and resumed keeping tally after the stabbing, while the defendant positively denied that he returned to the handball court after the assault.
While each of the witnesses for the prosecution who was at the scene of the crime, other than the laundry superintendent, stands convicted of multiple felonies, analysis and comparison of their several testimonies fail to reveal any fundamental or wholly irreconcilable inconsistencies. The evidence not only legally supports the verdict but in comparison with that offered by the defendant it appears overwhelming in persuasiveness.
3. Venue in the County of Sacramento Is Established by Proof that the Offense Was Committed within Folsom State Prison. In his third contention defendant asserts that the venue of the offense was never established in that none of the witnesses testified that any of the events related by him occurred in the county of Sacramento. The transcript discloses, however, that some of the witnesses testified that the acts referred to in their testimony occurred at Folsom prison, and defense counsel stipulated “that Folsom Prison is situated within the County of Sacramento, State of California. ’ ’ Moreover, as stated by the trial court, it could take judicial notice of the fact that Folsom prison is situated within the county of Sacramento. (Code Civ. Proc., §1875, [701]*701subd. 2; People v. Wright (1926), 79 Cal.App. 523, 525 [250 P. 204]; People v. Bastio (1942), 55 Cal.App.2d 615, 617 [131 P.2d 614].)
4. It Was Error to Instruct the Jury Contrary to the Provisions of Section 1138 of the Penal Code, but It Appears that No Prejudice Therefrom Was Suffered by Defendant. Defendant’s fourth contention—the only one which has semblance of merit—is based on the last paragraph of the charge of the court. In closing his instructions to the jury the trial judge stated, “I wish to say that from this time on, you will receive no visitors from any source whatever; neither will you send out any communications nor will any be sent to your room. You have now all that is to be said in this case, by the respective parties and by the Court. The case now remains with you.” (Italics supplied.) Section 1138 of the Penal Code provides that “After the jury have retired for deliberation, if there be any disagreement between them as to the testimony, or if they desire to be informed on any point of law arising in the cause, they must require the officer to conduct them into court. Upon being brought into court, the information required must be given in the presence of, or after notice to, the district attorney, and the defendant or his counsel, or after they have been called.”
Obviously it was improper to admonish the jury, “neither will you send out any communications. . . . You have now all that is to be said in this case, by the respective parties and by the Court.” The jury had the right to send out a communication to the court at any time it saw fit and it had the right to have testimony read or further instructions given. But the fact that it had these rights does not show that it had any occasion, in this case, to use them; nor, even if we assume that it may have wished to exercise such rights and felt precluded therefrom, does prejudice to the defendant appear possible.
The instructions given in this case, other than the single one under discussion, comprise a charge which is generally a model of excellence. The charge as a whole is clear, complete, concise; the language is plain; the rules stated are simple. There is no point of law as to which, in reason, the jury could have needed further information. The trial was not protracted: the jury was empaneled on Monday, September 21, 1942; the verdict was returned on Thursday, September 24. The deliberations were not prolonged: the [702]*702jurors retired at 2:58 p. m. and returned into court one hour and fifty minutes later, at 4:48 p. m., with their verdict. They were polled and each declared the verdict to be his.
By the instructions which were given, the jurors were advised as to every element entering into the crime charged; they were not only given the statutory rule and definition as to burden of proof and reasonable doubt, but they were also told that “The defendant is presumed to be innocent, and this presumption attaches at the beginning of the trial and remains throughout all stages of the trial,” that the plea of the defendant “puts in issue every material allegation of the information and charge, and it devolves upon the prosecution to establish beyond a reasonable doubt that he, the said defendant, is guilty of the crime charged against him in the information,” and that “Bach of the parties in this case is entitled to the independent judgment of each juror.” (Italics supplied.) In the light of these proper instructions as to the law governing their consideration of the case, it seems clear to us that the concluding instruction which purported to preclude the jury from asking for further information, if it prejudiced either party, must have tended to prejudice the plaintiff and favor the defendant, rather than vice versa. Under the instructions quoted, if there was any material disagreement among the jurors as to the evidence which, in the absence of the improper instruction, would have caused their asking to be brought into court for further information, such disagreement must certainly have tended to impede or prevent rather than to facilitate or cause arrival at a verdict of guilty. If any juror entertained a view of the evidence inconsistent with guilt beyond a reasonable doubt, he was told, it was his duty to vote for a verdict of not guilty. If this situation of disagreement had arisen and the jurors had felt precluded from asking to be brought into court and given further information, the verdict which was returned herein could never have been reached. With the jury instructed that each party was “entitled to the independent judgment of each juror,” that the burden of proof was on the prosecution, and that the defendant was entitled to the benefit of any reasonable doubt, it seems apparent that any disagreement among the jurors as to either facts or law, as to which they might have wanted, but felt prohibited from asking, further information, would have tended to prevent, rather than to cause, a verdict of guilty.
[703]*703We are satisfied, after an examination of the entire cause, including the evidence, that the error in the instruction noted has not prejudiced the defendant or resulted in a miscarriage of justice. (Cal. Const., art. VI, § 4%.)
5. The Record Shows that the Jury Was Informed that the Penalty for the Crime Charged Was Death. Defendant’s final contention—that the “Court erred in failing to instruct the jury that a verdict of guilty condemned the defendant to die”—is not supported in its factual base. The court read to the jury section 4500 of the Penal Code which provides that “Every person undergoing a life sentence in a State prison of this State, who, with malice aforethought, commits an assault upon the person of another with a deadly weapon or instrument, or by any means of force likely to produce great bodily injury, is punishable with death.” (Italics supplied.)
For the reasons hereinabove stated the judgment is affirmed.
