After a jury-waived trial in which the sole issue was the defendant’s criminal responsibility, the defendant, Francis E. Cullen, Jr., was convicted of assault with intent to murder (two counts), assault and battery by means of a dangerous weapon (two counts), and unlawfully carrying a firearm. The defendant appealed his convictions claiming that although “there may be some evidence supporting a conclusion of sanity . . . [t]he Commonwealth did not produce sufficient evidence
*226
. . . from which a reasonable trier of fact could infer the sanity of the Defendant beyond a reasonable doubt.” A divided panel of the Appeals Court affirmed the judgments.
Commonwealth
v.
Cullen,
We summarize the evidence. In the early morning of February 5, 1983, the defendant Cullen threw a rock at a marked police cruiser driving on Central Avenue in Milton. The police officer in the cruiser, Paul Nolan, pulled over and approached the defendant, who was standing in the driveway of his home, to inquire about the incident. Cullen did not respond to the inquiry. As Officer Nolan approached and repeated the question, Cullen drew an unlicensed handgun from his waist and fired three shots, two of which hit Officer Nolan. The defendant disappeared behind his house momentarily, only to return and fire upon Officer Charles Paris, who had arrived on the scene and was kneeling beside Officer Nolan, radioing for help. One bullet struck Officer Paris in the back, and another shot damaged the portable radio on Officer Nolan’s hip. Officer Paris turned and fired in the direction of Cullen, who then fled.
Additional police, arrived and soon after receiving a radio report of an attempted break-in at the residence of Cullen’s former lawyer, a few houses from Cullen’s home, one officer apprehended the defendant in the rear of that residence. Officer Michael Breen, with service revolver drawn, then ordered, “Frankie, give it up.” Cullen turned his back to Officer Breen and placed his hands on the side of the house, but as Officer Breen approached, began to back away. Believing him about to flee, Officer Breen grabbed Cullen from behind, restraining him. Both men fell to the ground. After Officer Paris handcuffed Cullen’s wrists behind his back, he searched for a handgun. Cullen “began to thrash about from left to right,” which gyrations soon revealed to the police a handgun under his back approximately at his beltline. Cullen had reloaded his gun before being apprehended. Prior to the incident, Cullen had been drinking with a friend for six or more hours.
*227 Cullen did not testify at trial, nor did he substantially contest these facts. His defense consisted of the oral testimony of one and the written report of a second psychiatric expert as to his lack of criminal responsibility for the two shootings. The expert testimony and report revealed that Cullen told the doctors that the Milton police were “out to get him,” that they, and other police departments from eastern Canada to New York City, had kept him under twenty-four hour surveillance for more than seven years. He asserted that his phone was bugged. The police played “mind games” with him that “let him kill people,” and caused “pins and needles” in various parts of his body. The police interfered with his love life, which Cullen said potentially included five hundred women whom he knew to be attracted to him, by telling women that he was a sex pervert. Cullen told the psychiatrist that he had purchased the handgun, which he had used in the assaults, “on the street,” had thrown a rock at the police cruiser, and had shot Officers Nolan and Paris in self defense to protect himself from the police. He told the psychiatrist that, while it would have been easy to kill the wounded Officer Nolan, he refrained from doing so because he had intended only to “put him out of service.” Cullen insisted that he had fled to his lawyer’s house only because “he was sure that the police would not kill him in front of . . . his attorney.”
Both psychiatrists concluded, on the basis of slightly different diagnoses, that Cullen lacked criminal responsibility under the test elaborated in
Commonwealth
v.
McHoul,
The issue is whether, after viewing the evidence in the light most favorable to the Commonwealth, any rational trier of fact could have found Cullen to be criminally responsible beyond a reasonable doubt.
Commonwealth
v.
Shelley,
The defendant does not argue that the Commonwealth had not presented sufficient evidence of his criminal responsibility by the close of its case-in-chief. Rather, he claims that the Commonwealth’s proof of the issue deteriorated between the time the Commonwealth rested and the close of all the evidence, and therefore the judge should have made a required finding of not guilty by insanity at the close of all the evidence. See
Commonwealth
v.
Lunde,
*229
Cullen asserts that the evidence produced by the Commonwealth did not meet its burden of proving his sanity because he introduced evidence from two psychiatric experts as to his lack of criminal responsibility for the shootings under the
McHoul
test. See
Commonwealth
v.
Kostka,
Further, in this case, there is no long history of mental illness or hospitalizations. See
Commonwealth
v.
Cole,
Finally, the judge was entitled to infer sanity from the facts underlying the crime and evidence of Cullen’s actions before and after the crime. Commonwealth v. Amaral, 389 Mass. *230 184, 192 (1983). Commonwealth v. Kostka, supra at 530-531. The defendant had steady employment as a crane operator. He lost his job not because of mental illness but because the plant closed. Aside from the report of one expert that Cullen had been in a residential treatment program of an unspecified type over twenty years before the shooting, 3 the defendant presented no records or evidence of psychiatric hospitalizations or treatment for mental illnesses.
Viewing the evidence in the light most favorable to the Commonwealth, the judge could conclude that the defendant was criminally responsible for his behavior. Cullen did not shoot wildly; rather, almost all of his shots hit either the clothing or bodies of the two police officers. The defendant’s flight to his lawyer’s house, and his surrender in response to the police officer’s shout to “give it up” indicate the defendant had the capacity to appreciate the criminality of his conduct. The judge could have inferred that Cullen’s thrashing on the ground was an attempt to reach his gun, and thus have an advantage on the police. Furthermore, the judge could consider whether the defendant’s conduct was related, not to a lack of criminal responsibility but to the fact the defendant had been drinking for six hours prior to the shooting. Inferences drawn from circumstantial evidence “need not be inescapable or necessary, so long as they are reasonable, possible and not unwarranted because too remote.”
Commonwealth
v.
Walter,
The judge, as the trier of fact, was in the best position to evaluate the evidence on the issue of the defendant’s sanity. *231 We conclude that, viewed in the light most favorable to the Commonwealth, the evidence was sufficient for the judge to find the defendant sane beyond a reasonable doubt. 4
Judgments affirmed.
Notes
The defendant’s reliance on
Commonwealth
v.
Guiliana,
Dr. Pontius altered her diagnosis during the trial and had not seen the police account of the shootings before making her diagnosis. Dr. Kelly apparently had made his report unaware of the defendant’s six hours of drinking before the shootings.
Dr. Kelly also mentioned in his report that the defendant had been referred for psychiatric treatment in connection with several unrelated arrests.
In his dissent to the Appeals Court decision, Justice Kass noted “the extreme thinness of evidence” on Cullen’s criminal responsibility.
