The defendant was convicted of murder in the first degree of a father and a son. He was also convicted *725 of breaking and entering a dwelling house in the daytime with intent to commit larceny and to put a person therein in fear. He received concurrent life sentences on the murder convictions, and a concurrent sentencе on the breaking and entering conviction.
The defendant argues four issues and urges that, if the convictions of murder in the first degree are not reversed, this court should exercise its power and duty under G. L. c. 278, § 33E, to direct the entry of verdicts of a lesser degree of guilt. We affirm the convictions and see no basis for reducing the verdicts on the murder cоnvictions.
1. The defendant argues that the judge erred in declining to instruct the jury on a possible verdict of manslaughter. The defendant’s counsel, who is not his counsel on appeal, requested such an instruction only in general terms, without specifying whether the request related to voluntary or involuntary manslaughter, or both. Nor did he state the theory on whiсh he believed an instruction was required. 1 We conclude that there was no prejudicial error in the failure to give a manslaughter instruction.
In support of his argument, the defendant relies on the testimony of his former girlfriend, who testified for the Commonwealth concerning inculpatory statements that she said the defendant made to her. We summarize this witness’s testimony concerning the defendant’s statements to her. The defendant went downstairs from the apartment where he lived and, intending to steal money, entered the victims’ apartment which he thought was unoccupied. The younger victim, the son, was there watching television. *726 The son told the defendant that he was going to call the police. The defendant replied, “Wait a minute, no. I will just leave.” The son said, “No,” grabbed the defendant, and “pulled him back.” They started fighting. The son scratched the defendant on the face. When the son grabbed the telephone to call the police, the defendant strangled the son “with the telephone.” While the defendant was strangling the son, the victim’s father walked in, carrying grocery bags. The father went to aid his son, who was already on the floor. The father hit the defendant. They fought. The defendant used Kung Fu and karate to knock the father down, but he got back up three or four times. The defendant had something in his hand, but he did not tell the witness what it was. He stabbed the father “around his neck.” After stabbing the fathеr several times, the defendant “just went off on him.” He did not enter the apartment intending to kill the victims. He killed them because he did not want to go back to jail. The defendant asked his girlfriend to say he was with her at the time of the crimes.
A medical examiner testified that he found a telephone extension cord tied around the son’s neck and bruises on his head and neck, some of which were consistent with manual strangulation. The son died of asphyxiation due to strangulation. The medical examiner testified further that the father appeared to be about eighty-four years old. The father died of numerous stab wounds on his neck; he had other wounds and bruises elsewhere on his body.
It is well established that, if any view of the evidence in a case would permit a finding of manslaughter rather than murder, a manslaughter charge should be given. See
Commonwealth
v.
Johnson,
Voluntary “manslaughter . . . [is] a killing from a sudden transport of passion or heat of blood, upon a reasonable provocation and without malice, or upon sudden combat.”
Commonwealth
v.
Soaris,
There was no evidence that raised a reasonable doubt whether the defendant formed an intent to kill in a transport of passion or in the heat of blood, “with the result that the homicide [was] unlawful but, the element of malice being missing, the crime [might be] mitigated from murder to manslaughter.”
Commonwealth
v.
Kendrick, supra
at 212. There may indeed have been “combat,” in the limited sense that struggles occurred in which blows were exchanged. However, physical contact between a defendant and a victim is not always sufficient to warrant a manslaughter instruction, even when the victim initiated the contact. See
Commonwealth
v.
Rembiszewski,
As to the eighty-four-year old father, the evidenсe raises no rational possibility of provocation justifying the use of deadly force as a response in the heat of passion on sudden combat. There was evidence that, when the father discovered the defendant strangling his son, the father began “hitting him and banging back at him.” If these blows presented any threat of serious harm to the defendant, their effect had passed when the defendant knocked the father down several times. See
Commonwealth
v.
Zukoski,
As to the son, the defendant relies on evidence that the son prevented the defendant from leaving the apartment and struck the first blow in the struggle which ensued. Thereafter the evidence leaves the circumstances to pure surmise. In the absence оf any evidence as to the circumstances of the struggle, no reasonable doubt was raised as to whether the defendant reacted on reasonable provocation. The jury could not be permitted merely to speculate on whether the defendant in the course of the struggle might have been roused to the heat of passion. 2
*729
The defendant also argues that a manslaughter charge was warranted because the jury could have found on the evidence that he acted in self-defense but used excessive force. See
Commonwealth
v.
Kendrick,
*730
The defendant argues further that a charge on involuntary manslaughter was required by the evidence, as to the death оf the son.
4
A consideration of the evidence shows that the jury would not have been warranted in concluding that the son’s death was “unintentionally caused by an act which constitute^] such a disregard of probable harmful bonsequences to another as to amount to wanton or reckless conduct.”
Commonwealth
v.
Vanderpool,
2. The defendant argues that answers he gave to questions by the police, six and eight days after the homicides, should have been suppressеd. The questioning was not preceded by Miranda warnings. He contends further that the police first learned of the existence of his girlfriend as a result of these interrogations and that, therefore, his girlfriend’s testimony concerning his incriminating statements should also be suppressed.
In each instance, the defendant, who was one of several suspеcts, went to the police station voluntarily at the request of the police, submitted to questioning by a police officer, took a polygraph test, and left. In denying the motion to suppress, the judge made findings, fully warranted by the evidence, that the defendant was not taken into custody, detained against his will, or otherwise deprived of his freеdom. See
Oregon
v.
Mathiason,
The defendant’s claim that the judge believed that Miranda warnings would have been required only if the defendant were formally under arrеst is without support in the record.
3. The defendant argues that his statements to the police should have been excluded as incompetent hearsay, and that, in any event, certain remarks he made in the course of those statements should have been excluded as irrelevant and highly prejudicial. The short answer to these contеntions is that, although the judge gave defense counsel several opportunities to do so, defense counsel declined to object to the admission of any of these statements. These arguments may not be raised for the first time on appeal.
Guillemette
v.
Commonwealth,
We conclude there was no errоr, much less a miscarriage of justice, in admitting the defendant’s statements. Those statements, which concerned the defendant’s conduct before and after the time of the homicide, set forth the defendant’s activities and laid a base for the testimony of his girlfriend. They were properly admitted as statements by the accused of facts pertinent to the issue of his involvement in
*732
the crimes, insufficient in themselves to warrant conclusions but tending, when coupled with other evidence, to establish guilt.
Commonwealth
v.
Bonomi,
The defendant’s references to his prior incarcerations were admissible, not as evidence of prior bad conduct to prove he committed the present crimes, but as tending to establish a motive for the killings. See
Commonwealth
v.
Hoffer,
4. On the sixth day of trial, the defendant moved orally to have data (“charts” and “graphs”) from the two polygraph examinations administered to him at the police station analyzed by an expert. The judge denied the motion.
At the time of trial,
Commonwealth
v. A
Juvenile,
*733 The tests had already been conducted by a person whose qualifications were unclear at best. The importance of the examiner’s skill and qualifications, of the appropriate choice of test questions, and of the proper supervision of the test conditions and procedures were noted in the Vitello case. Id. at 439 & 454. The defendant made no attempt to show any of the circumstances of the two tests, or even that the “charts” and “graphs” were available at the time of trial.
There was no abuse of discretion in the deniаl of a motion, made inexplicably late in the trial, for appointment of an expert to analyze polygraph data generated under undisclosed test conditions by a person of undisclosed competence.
5. A review of the transcript and consideration of the defendant’s various arguments reveal no occasion to alter the verdicts of guilty of first degree murder under G. L. c. 278, § 33E.
Judgments affirmed.
Notes
As to the elements of voluntary manslaughter, see
Commonwealth
v.
Kendrick,
While we will review the refusal of a judge to charge on manslaughter when such a general objection is lodged, the judge would have been justified in requiring the defendant to suggest the specific manslaughter instruction or instructions he wanted. If the judge had required him to do so, on appeal we would have held the defendant to his choice or choices.
There is a further reason why the defendant’s conviction of murdering the son should not be reversed. Any failure to give a manslaughter charge
*729
was not prejudicial to the defendant. We know from the verdicts on the murder indictments that the jury found that the defendant killed the victims. Any homicide during the commission of a felony
(Commonwealth
v.
LePage,
The defendant does not argue here, nor did he argue at trial, that he was entitled to a charge on self-defense, which (if accеpted by the jury) would completely exonerate him. The facts on no hypothesis called for such a charge on self-defense. There was no evidence to suggest (and thus warrant a reasonable doubt) that the defendant “had availed himself of all proper means to avoid physical combat before resorting to the use of deadly force” and had “used no more force than was reasonably necessary in all the circumstances of the case.”
Commonwealth
v.
Harrington,
Because the defendant received concurrent life sentences, success solely in this argument (and in any other argument directed to only one murder conviction) seemingly would offer little practical benefit for the defendant.
