    Commonwealth vs. Bruce W. Haglund.
    December 3, 1976.
   The defendant appeals pursuant to G. L. c. 278, §§ 33A-33G, from his convictions of arson and manslaughter. The defendant’s assignments of error challenge the denial of his motions (1) to suppress statements he had made to the police and (2) to ask certain questions of prospective jurors. 1. The judge, who made detailed findings, properly considered the defendant’s mental condition in determining if the defendant’s confession was voluntary and the product of a rational mind. His handling of this matter comported with the test to determine voluntariness suggested in Eisen v. Picard, 452 F.2d 860, 863-865 (1st Cir. 1971), cert. den. 406 U.S. 950 (1972). The judge heard testimony on the question whether the defendant was a pathological liar and found that the antisocial personality which was attributed to the defendant by the two psychiatrists who testified in his behalf at the hearing on the motion to suppress was not of such character and intensity as to deprive the defendant of his “free intellect and his freedom of choice.” Contrast Blackburn v. Alabama, 361 U.S. 199, 207-209 (1960). The trial judge’s preliminary determination (see Jackson v. Denno, 378 U.S. 368, 392-394 [1964]) that the defendant’s confession was voluntary is supported by substantial evidence. See Commonwealth v. Roy, 2 Mass. App. Ct. 14, 20-21 (1974). There was no error in allowing the defendant’s confession in evidence. See Commonwealth v. White, 362 Mass. 193, 196 (1972); Commonwealth v. Jackson, 3 Mass. App. Ct. 770, 771 (1975). 2. There was substantial basis for the judge’s finding that the defendant’s confinement was not so inherently oppressive as to induce him involuntarily to confess to the crimes charged. See Lego v. Twomey, 404 U.S. 477, 489 (1972); Commonwealth v. Johnson, 3 Mass. App. Ct. 226, 231 (1975); Commonwealth v. Jackson, supra. There was no evidence of police coercion designed to elicit a confession from the defendant. 3. The defendant claims error in that his confession was not preceded by an unequivocal waiver of his right to counsel. The defendant received numerous Miranda warnings from various law enforcement officials, and, on at least two specific occasions, in the context of giving him the entire set of Miranda warnings, see Commonwealth v. Fielding, 371 Mass. 91, 114-115 (1976), he was informed of his right to have an attorney represent him without charge. See Commonwealth v. Johnson, 3 Mass. App. Ct. at 229-231, and cases cited therein. The judge’s determination that the defendant understood this right and voluntarily waived it is adequately supported by the evidence and we will not disturb it. Commonwealth v. Roy, supra. Commonwealth v. Black, ante, 512, 516 (1976). See Miranda v. Arizona, 384 U.S. 436, 475 (1966); Commonwealth v. Johnson, 3 Mass. App. Ct. at 230-231, & n.4. 4. The nature and the extent of the examination of prospective jurors lies within the sound discretion of the trial judge, see Commonwealth v. Ricard, 355 Mass. 509, 510-511 (1969); Commonwealth v. Pinckney, 365 Mass. 70, 72-73 (1974), subject to statutory provisions (see, in this regard, G. L. c. 234, § 28, as amended through St. 1973, c. 919), and the constitutional requirement enunciated in Ham v. South Carolina, 409 U.S. 524, 526-529 (1973), and Ristaino v. Ross, 424 U.S. 589 (1976), and applied in numerous Massachusetts cases. See, e.g., Commonwealth v. Ross, 361 Mass. 665, 682 (1972), judgment vacated 410 U.S. 901, aff’d on rehearing 363 Mass. 665, cert. den. 414 U.S. 1080 (1973). The judge did not err in denying the defendant’s motion to question prospective jurors about possible biases regarding psychiatric evidence or about their opinions concerning the reliability of confessions. See Commonwealth v. Ricard, supra; Commonwealth v. Smith, 357 Mass. 168, 176 (1970), and case cited therein. Compare Commonwealth v. Killelea, 370 Mass. 638, 649-650, & n.3 (1976).

Susan J. Baronoff for the defendant.

Helen M. Doona, Assistant District Attorney, for the Commonwealth.

Judgments affirmed. 
      
       In one instance, immediately following the defendant’s rejection of a suggestion by the sheriff that he call his “family” lawyer, the sheriff read to the defendant the entire warning from a so called Miranda card. The defendant then indicated that he still “wanted to get it off his chest.”
