Appleby was found guilty of the first degree murder of Mary McCue, a seventy-four year old resident of the Hotel Touraine, a lodging house in Lynn. Her naked, bloody corpse was found in her room about 9 p.m. on Sunday, March 10, 1968. There was evidence of sexual assaults and other abuses which need not be set forth in detail. The jury recommended that the death sentence be not imposed.
The trial was conducted subject to G. L. c. 278, §§ 33A-33G. Appleby in his appeal assigns as error (a) the trial judge’s pre-trial denial of motions to suppress certain evidence, which was later admitted, and to dismiss the in *409 dictment, (b) the denial of motions for directed verdicts, and (c) certain portions of the judge’s instructions to the jury.
The trial judge for two days received testimony with reference to the motions to suppress evidence and to dismiss the indictment. After making careful findings, he allowed the motion to suppress so far as it related to statements by Appleby at his interrogation at the Lynn police station on the early morning of March 11, 1968. Otherwise he denied the motions. Much of the evidence received at the pre-trial hearing was again introduced in substantially the same form before the jury at trial.
On the motion to suppress, the trial judge, upon somewhat conflicting evidence which warranted his findings, found the following facts. When Mary McCue’s body was discovered in room 116 of the Touraine, the police were called and came promptly to the scene. Robert B. Williams, as tenant and full time occupant, rented rooms 101 and 102. For about a month, he had permitted Appleby to stay with him. Appleby paid no rent and sometimes slept in a chair. Lieutenant Perlino received permission from Williams 1 to look around his apartment with other officers. Appleby’s trousers (as the evidence showed, on a chair in plain view), and shoes, both of which had stains which "resembled blood stains,” and his wallet were in the room. The police took them for examination.
About 3 a.m. on Monday, March 11, Appleby was asked to go to the police station. He then "was effectively under arrest.” He was questioned until 5 a.m. Shortly after the questioning began, he was warned "pursuant to”
Miranda
v.
Arizona,
*410 During the inquiry at the police station, Appleby’s “shorts were examined, fingernail scrapings were taken, and . . . ^Appleby] -underwent a benzidine test” of portions of his body to check whether evidence of blood marks existed. Appleby had no counsel present.
The judge made the following rulings. (1) Williams as tenant of rooms 101 and 102 could “permit the entrance of whomever he wished” and his “consent, validly obtained, was sufficient authorization for the police to enter and search those rooms”; (2) No right of Appleby was violated by the “search and seizure subsequent to validly obtained consent by [Williams,] an appropriate party”; (3) The benzidine test and the inspections of Appleby’s shorts and fingernail scrapings “are not events requiring the presence of counsel.” 2
The following additional facts could have been found from the evidence at trial. Mary McCue was last seen alive about 7:30 p.m. on Saturday, March 9, by Williams and Henry M. Zane, another lodger at the Touraine. Appleby had gone to a bar with Williams on Saturday morning. Appleby returned to Williams's rooms after midnight, perhaps as late as 1 a.m., early Sunday morning. He had been drinking. Williams described him as staggering. Zane, who saw him upon his return, did not think him drunk. Appleby just “flopped” in a chair. Williams found him the next morning “flopped on the floor on his face,” just waking. They had breakfast together. Appleby left during the day to attend the christening of his sister’s child. He borrowed a suit from Williams to wear to the christening. Appleby went to his sister’s house, attended the christening in the afternoon, and then went off to work on Sunday evening. That evening Mary McCue’s body was found and the investigations already described took place.
Joseph V. Lanzetta, a chemist employed by the State police, testified concerning the tests administered to Appleby *411 at the police station, to his clothing and fingernail scrapings, and to various items found on or near Mary McCue’s body. This testimony is mentioned in greater detail later in this opinion.
1. We assume (without deciding) that Appleby has standing to question the propriety of the search of Williams’s room (see
Jones
v.
United States,
The judge, on the evidence, reasonably could conclude that the consent was voluntary. Williams should have known that everyone in the building, particularly any person acquainted with Mary McCue, must be under suspicion. Since he had nothing to hide, he had every incentive to clear himself. He testified at trial that the police “are always welcome in my room.” Cf.
Bumper
v.
North Carolina,
Appleby’s trousers were in plain view on a chair. No search was required of any receptacle or enclosed area belonging only to Appleby. They were seen by the officers when lawfully on the premises. See
Harris
v.
United States,
*412
2. About 3 a.m. on Monday, March 11, two police officers went to Appleby’s place of work. They told him that Captain Silk “would like to talk to him at the police station,” and “he very readily agreed to go.” There he appeared before several officers. He was asked about his activities on Saturday, March 9. He then was warned, as the judge found. Appleby was wearing a jersey shirt and shorts (then seized) on which blood was later found. Benzidine tests were made of Appleby’s hands, lower body, thighs, and genitals. These tests revealed the presence of heavy concentrations of blood. Photographs of the results of these tests were made. Fingernail clippings were taken from Appleby’s hands. These were tested later. A shirt worn by him on Saturday was obtained from his sister.
Appleby was not formally booked until shortly after 5 a.m. when the tests and police interrogation had been completed. Although the police denied that he was under arrest when taken into the station, it was reasonable for the judge to infer, as he did, that Appleby was effectively under arrest while at the police station. He certainly would not have been allowed to leave if he had tried to do so, in the face of the substantial evidence providing probable cause for his arrest. Blood had been found around the crotch of bis trousers and on his shoes, as well as on Mary McCue. He had been living on the same floor of the Touraine premises as the victim and knew her. He had been present on that floor on Sunday morning (shortly after midnight and at *413 breakfast) between, the last occasion when Mary McCue had been seen alive and the discovery of her body. An autopsy made about 12:30 a.m. on Monday, March 11, had revealed that the victim had died from strangulation approximately twenty-four to forty-eight hours earlier. 4
The examination of clothing worn by Appleby at the police station was a search incidental to his arrest. That arrest was based on circumstances known directly to the police, which reasonably led to the belief that he had committed a felony.
Commonwealth
v.
Holmes,
The evidence obtained by the benzidine test, the fingernail test, and the analysis of garments for blood did not cause any testimonial communication or statement of any type by Appleby. Thus no question of self-incrimination was presented. A competent expert merely observed physical facts by appropriate scientific means. Appleby had no proper claim to the presence or advice of counsel (see the
Schmerber
case, at pp. 765-766;
United States
v.
Wade,
The examination of Appleby’s clothing and tests upon his
*414
body at the police station did not depend on any interrogation of Appleby in violation of
Miranda
v.
Arizona,
3. The defendant’s motion to dismiss the indictment seems to be based on the alleged illegality of the search of Williams’s room, the seizure of Appleby’s trousers, and the examinations of Appleby’s person and garments at the police station in the absence of counsel. These actions were valid. The motion to dismiss in any event was properly denied under the rule stated in
Commonwealth
v.
Galvin,
4. There was no error in denying motions for a directed verdict. Appleby had opportunity to be in the Touraine at the crucial period. He was seen there on the night before the victim’s corpse was discovered. The scientific evidence was sufficiently strong to permit the jury to find Appleby guilty beyond a reasonable doubt. See
Commonwealth
v.
Perez,
Lanzetta, the State police chemist, testified that traces of bloody tissue, fecal stains, and semen stains were found on Mary McCue’s body, clothing, and bed sheet and on Appleby’s clothing; that human hair similar in color and *415 appearance to that of Mary McCue was found on Appleby’s trousers and shoes; that wool fibers consistent with those of Mary McCue’s clothing were found in her fingernail clippings and those of Appleby; that a feather was found on Appleby’s shoe which resembled (in color and microscopic appearance) a feather found on Mary McCue’s clothing; and that fragments of egg shells were on the sole of Appleby’s shoe and on the floor of Mary McCue’s room. Reference has already been made to the highly significant benzidine tests which revealed bloodstains on Appleby’s body and clothing.
5. The trial judge instructed the jury that if they found Appleby killed Mary McCue, but by reason of intoxication was “incapable of conceiving a deliberately premeditated intention to kill,” he would not be guilty of murder in the first degree, but only of murder in the second degree. At the close of the charge, Appleby’s counsel claimed an exception to the judge’s “failure ... to tell the jury that drunkenness is a fit subject for the [jury’s] consideration . . . with respect to the element of specific intent in . . . first degree murder which is other than murder with deliberate, premeditated malice aforethought.” The judge gave no further instruction. Appleby’s attorney now argues that voluntary intoxication should be considered also as affecting the existence of “the express malice . . . inherent in . . . murder with extreme atrocity or cruelty.”
Intoxication does bear on the issue of deliberately premeditated intention to kill.
Commonwealth
v.
Taylor,
6. We perceive no reason in justice for disturbing the judgment by the exercise of the powers of this court under G. L. c. 278, § 33E (as amended through St. 1962, c. 453).
Judgment affirmed.
Notes
Williams, at the motion hearing, testified that the police did not ask his consent to enter his room. The police witnesses, on the other hand, testified that Williams (a) invited them to his room, (b) indicated that they “could look around,” (c) said that he had “nothing to hide,” (d) cooperatively offered to help in any way possible, and (e) told them that they could take the trousers and shoes, which were not his, but belonged to Appleby.
The judge also ruled that “ambiguity . . . surrounding the alleged waiver . . . [at the police station fell] short of convincing . . . [him] that” Appleby “knowingly and intelligently waived his right to have counsel at his interrogation.” The oral statements then received tended to incriminate Appleby. These were suppressed and were not offered in evidence at trial.
It was, of course, important for the police promptly to take possession of tangible evidence of guilt which properly came to their attention immediately after the discovery of a most serious crime. If not seized, Appleby’s trousers and shoes might have been concealed or destroyed, or have disappeared. See
Schmerber
v.
California,
Appleby and Mary McCue both had type A blood. This fact probably was not known at the time of the police interrogation. The evidence indicates that type A is the second most common type of blood, and that thirty-five to forty per cent of the population of the Commonwealth have this type.
There is no denial of equal protection of .the laws in (a) permitting intoxication to be considered on the issue whether there exists deliberately premeditated malice aforethought, to which it has reasonable relevance; and (b) refusing to give it consideration on the issue of the existence of extreme atrocity and cruelty as to which intent to be cruel is not pertinent. The statute, as interpreted by this court (see St. 1858, c. 154), applies to all offenders equally in like circumstances. Cf.
