After separate trials, the defendant and Richard J. Viveiros were convicted of second degree murder in the death *437 of Joseph Brum. 1 On appeal, the defendant claims that the evidence was insufficient to prove that his acts were the proximate cause of Brum’s death, that errors in the instructions created a substantial risk of a miscarriage of justice, and that the judge erred in allowing a leather wrist band with metal spikes on it to be displayed to the jury. We affirm the defendant’s conviction.
On the basis of the Commonwealth’s evidence against the defendant, the jury could have found the following facts. During the afternoon of July 21, 1987, Brum, his two teenaged sons, a neighbor, the defendant, and Viveiros were drinking beer and wine and socializing on the front porch of 47 Boutwell Street in Fall River. When the discussion turned to the subject of gangs, Viveiros and the defendant became upset and expressed anger towards Brum. Viveiros said to the defendant, “Let’s get the fuck out of here,” and to Brum, “We’ll be back.” The defendant shook Brum’s hand. Viveiros and the defendant then left the porch and drove away. Brum, very drunk, crossed the street to a parked truck in which he lay down. After a while he attempted to get out of the truck but fell from a step. First his hands, then his face, then his feet, and eventually his whole body hit the ground. He got up, staggered, and reentered the truck. Fifteen or twenty minutes later, the defendant and Viveiros returned to the area in a car. They brought with them a baseball bat, and the defendant wore a black leather wrist band with metal spikes on it. For a short while they visited, and drank beer, in an apartment on the first floor of 47 Boutwell Street. Then they approached Brum, said something to him, and proceeded for the next twenty minutes or so to beat him. The defendant hit Brum in the face with the spiked wrist band. *438 When Brum fell, they kicked him with their boots and hit him with the bat all over his body, including his stomach. During the beating, either the defendant or Viveiros warned Brum that if he were to. “[get] anyone else into it,” they would come back and kill him. With Brum lying on the ground covered with blood, the defendant and Viveiros gave a “thumbs up” sign to an observer. One of them told Brum, “You’re lucky you’re staying there alive,” and they drove away. Brum was taken to the hospital and died the next day. Dr. George Lauro performed an autopsy and found that the cause of death was “peritonitis secondary to an infarcted bowel resulting from blunt trauma.”
1.
Causation.
“[P]roximate cause ... ‘is a cause, which, in the natural and continuous sequence, produces the death, and without which the death would not have occurred.’ California Jury Instructions, Criminal § 8.55 (4th rev. ed. 1979).”
Commonwealth
v.
Rhoades,
Dr. Lauro’s opinion was that a blunt force injury caused Brum’s peritonitis which, in turn, caused his death. The blunt force, according to Dr. Lauro, could have been any one of a number of instruments, such as a fist, a heel of a shoe, or a baseball bat, or it could have been the striking of the ground in a fall. The defendant contends that Dr. Lauro’s testimony does not support the verdict because, given the evidence that Brum sustained a fall, the testimony was equally consistent with two propositions: that Brum’s fatal peritonitis
*439
was caused by the fall, for which the defendant was not responsible; and that it was caused by the beating, for which he was responsible. A verdict of guilty, the defendant therefore contends, could only have been based upon pure speculation. See
Berry
v.
Commonwealth,
We do not think, however, that a fair appraisal of the evidence would have left a rational fact finder in the realm of speculation. The witness who testified about the fall was clear that Brum first hit the ground with his hands, then his head, then his feet, and then the rest of his body. On the other hand, the testimony about the beating indicated that it was severe and protracted and that Brum received multiple blows to his abdominal area with a baseball bat and shod feet. The jury could reasonably have inferred that the trauma to Brum’s abdominal area was substantially greater from the beating than from the fall and that it was the beating, therefore, which caused the peritonitis. While a reasonable juror could have believed that it was possible that the fall was the blunt force that caused the fatal condition, the Commonwealth was not required to “exclude every reasonable hypothesis of innocence.”
Commonwealth
v.
Merola,
The defendant produced testimony from Dr. Phillip Walton Smith, who treated Brum when he arrived at the hospital. Dr. Smith testified that, in his opinion, Brum died as a result of cardiac arrest, caused by delirium tremens which, in turn, resulted from excessive alcohol consumption. (Brum’s blood alcohol level upon entering the hospital was recorded at levels which varied between .42 and .49.) Even had the defendant renewed his motion for a required finding of not guilty at the conclusion of all the evidence, which he did not, Dr. Smith’s testimony would not affect our conclusion as to the validity of the verdict. The conflict in the evidence between Dr. Smith’s testimony, in which there were weaknesses,
*440
3
and Dr. Lauro’s did not cause the Commonwealth’s case to “deteriorate,” and it was for the jury to resolve the conflict. See
Commonwealth
v.
Hastings,
2.
Instructions on malice.
The judge directed a verdict as to so much of the indictment as alleged first degree murder. As to second degree murder, the judge charged the jury on all three prongs of malice. On the first two prongs of malice, intent to kill and intent to do grievous bodily harm, the judge instructed the jury that they could consider the defendant’s intoxication in determining whether he had the requisite intent. See
Commonwealth
v.
Grey,
A correct instruction would have informed the jurors that they could consider the defendant’s intoxication in determining his knowledge of the relevant circumstances, the only subjective part of the third prong of malice. See
Commonwealth
v.
Blake,
There was considerable evidence before the jury that the defendant had been drinking beer and wine and was intoxicated. While on the porch, the entire group socializing there was described by witnesses as “tipsy” and “drunk,” and Viveiros and the defendant were described as “wobbly” as they walked away from the porch. When they returned to the area about an hour later, they were described by a witness as “drunk,” and before the attack they had yet another beer.
On the other hand, the actions and comments of the defendant and Viveiros throughout the episode strongly indicate awareness of the relevant circumstances. The defendant left the group in the company of Viveiros after an argument with Brum and after Viveiros promised to return. They drove to some location where they changed clothes and obtained the bat and spiked wrist band. They drove back to the area and found Brum in the truck. After they talked to Brum, the defendant joined Viveiros in the beating. In the course of the beating, either the defendant or Viveiros said, “if [Brum] got anyone else into it, . . . they were going to come back and kill him.” When a neighbor said, “Look, don’t you think you hit him enough? Leave him alone. I’ll call the cop,” one of them replied, “Call the cop. What the hell do I care?” As they were leaving, one of them said to Brum as he lay on the ground, “You’re lucky you’re staying there alive.” The defendant gave a “thumbs-up” gesture to a bystander as he left with Viveiros before driving away. 4
*442
In the two cases in which convictions were reversed for similar errors in the charge on malice, not only did the defendant request a correct instruction at trial, but also the evidence of the defendant’s incapacity due to consumption of alcohol was far more substantial. Thus, in
Commonwealth
v. Sama, 411 Mass, at 298-299, “[t]he defendant presented credible evidence of debilitating intoxication bearing on his ability to possess meaningful knowledge of the circumstances at the time of the victim’s death. The defendant testified that he long has suffered from uncontrolled alcoholism which in the past has caused him to experience memory loss. Moreover, the defendant’s father testified and described his son’s chronic substance abuse and what he perceived to be his son’s resulting mental impairment. Lastly, an expert witness testified on behalf of the defendant, and she opined that the defendant could have hallucinated at the time of the killing, due to the effect of the alcohol and drugs he ingested earlier that day.” In
Commonwealth
v.
McLean,
There are other cases in which a similar error in the instructions was made and there was evidence of significant consumption of alcohol, but the convictions were not reversed. See
Commonwealth
v.
Sires,
413 Mass, at 300 (even though the defendant requested a correct instruction, evidence that the defendant was intoxicated and did not remember anything after shooting his mother did not raise a jury issue requiring the instruction);
Commonwealth
v.
Costa,
414 Mass, at 628 (failure to instruct the jury correctly on the third prong of malice was not reversible error, even in light of evidence that the defendant had several beers, whiskey, and a “scorpion bowl” before shooting the victim, because the jury found first degree murder, and also because the evidence of the defendant’s actions supported the conclusion
*443
that he was capable of having the requisite knowledge). See also
Commonwealth
v.
Freiberg,
In this case there was neither testimony from the defendant as to his impairment at the time of the attack nor testimony from an expert, such as is almost always included in such cases, see
Commonwealth
v.
Cruz,
3.
Instruction oh reasonable doubt.
When the judge charged the jury on the definition of reasonable doubt, she omitted the word “cannot,” thereby presenting in one sentence a definition that was “the exact inverse of what it should have been.”
Commonwealth
v.
Wood,
*444
“To determine whether a definition of reasonable doubt accurately conveys the meaning of the term, it is necessary to consider the charge as a whole.”
Commonwealth
v.
Watkins,
4. Display of leather wrist band with metal spikes. The defendant filed a motion in limine requesting that the judge exclude from evidence the leather wrist band with spikes found in a search of Viveiros’s home. The defendant contended that no blood was found on the wrist band and that no witness would be able to identify it as the one used in the alleged offense. Except with respect to the Commonwealth’s opening statement, the motion in limine was denied. During trial, one witness stated that, when she saw the defendant give her a “thumbs up” gesture prior to driving away from the scene, she noticed that “[h]e had a black bracelet with — I don’t know what you call it. You know like a biker’s bracelet. . . those black bracelets with studs on it.” A second witness stated that she saw that the defendant “had a black wrist thing ... it had like spikes on it; and he started, you know, hitting [the victim] right in the face with that .... I did see a black band on him with some spikes on it.” Over the defendant’s objection, the prosecutor was given permission to show the wrist band to the witness and, implicitly, to the jury. When asked if she recognized it, the witness said, “this is something like what he was wearing.” The wrist band was then marked for identification.
So long as it was displayed to the jury, we think it makes little difference whether the wrist band was admitted as an exhibit or merely marked for identification. It was not an abuse of discretion for the judge to have allowed the wrist band, similar but perhaps not identical to the one used, to be displayed to the jury. See
Commonwealth
v.
Ellis,
Judgment affirmed.
Notes
This court affirmed Viveiros’s conviction and an order denying a motion for new trial in an unpublished order. See
Commonwealth
v.
Viveiros, 29
Mass. App. Ct. 1102 (1990). After the defendant’s conviction, Viveiros brought a second motion for a new trial, claiming inelfectiveness of trial counsel in failing to present the medical evidence tending to negate causation which had been presented at the defendant’s trial. That motion was also denied, and the denial was affirmed in another unpublished order. See
Commonwealth
v.
Viveiros,
The defendant concedes that the verdict would not be invalid on this ground as to the lesser included offense of assault and battery.
For example, Dr. Smith admitted to having little knowledge concerning acute alcoholism, he was both unaware of and unconcerned about the information in the medical records showing that the victim had symptoms of peritonitis from the time of his admission to the hospital, and he admitted that, had he had the autopsy results when he first rendered his opinion, he would have listed peritonitis as one of the diagnoses.
The evidence indicates that the defendant fled the area soon after the incident. Both Viveiros’s and the defendant’s vehicles were at Viveiros’s residence at 3:30 a.m. on the day following Brum’s death, but neither Viveiros nor the defendant was there. Although the police were looking for him, the defendant was not apprehended until ten months later when he was found hiding under a bed at his mother’s house.
The facts, which are not recited in the rescript opinion, are from the record in the case.
