After convictions on indictments for attempted burning of a motor vehicle, malicious injury to a motor vehicle, and larceny of a motor vehicle, the defendant has raised three claims of error regarding fruits of a search and pretrial interrogation which he thinks ought to have been suppressed. He also raises four claims of error in the conduct of the trial. We affirm.
1. The Propriety of the Investigatory Stop.
At the outset we are asked to consider whether justification existed for an investigatory stop of an automobile and interrogation of its occupants. The applicable principles have been much discussed. See
Commonwealth
v.
Riggins,
*660
In
United States
v.
Cortez,
We now apply these principles to the facts found by the trial judge in the case at hand when he acted on a suppression motion. See
Commonwealth
v.
Moon,
Both police officers turned on their blue flashing lights, but the oncoming car failed to stop and proceeded down the dead-end portion of Greenlodge Street. The police made a U-turn, gave chase and, after about a quarter of a mile, the car stopped.
What, if any, particularized suspicion may be deduced from these facts? First, a serious crime was apparently in progress. See
Commonwealth
v.
Breen,
*662 2. The Search of the Trunk of Egan’s Car.
When they first approached Egan’s car, the police officers did so with guns drawn. They noticed a Brookline police sticker on the car and inquired if Egan was a police officer. Egan established that he was a member of the Brook-line force and the Canton policemen, having also checked the glove compartment of Egan’s car for weapons, bolstered their own. When asked about the gas-soaked car on Elm Street, Egan and his passenger professed ignorance. Sullivan asked to have a look at the trunk of Egan’s car; the latter said he did not have a key. A registration check of both vehicles, the one Egan was driving and the abandoned Pontiac, ensued and established that the owner of each lived in Brookline. That coincidence reasonably excited the suspicions of the Canton police officers that Egan might be connected with the incipient burning.
By this time about five minutes had elapsed and a third member of the Canton police, Sergeant Lenhart, arrived on the scene. Lenhart repeated the request to examine the trunk of Egan’s car. This time the defendant did not protest that he lacked a key. The trial judge, who also heard the suppression motion, found that Egan consented to a search of the trunk and that, indeed, Egan himself opened the trunk lid. In the trunk Lenhart found a red cannister; it smelled of gasoline and felt, Lenhart said, “approximately a quarter full.”
Egan attacks the search and the finding that it was consented to on the grounds that the circumstances were inherently coercive and that he and his companion were detained beyond the scope of a threshold inquiry. Contrast
Dunaway
v.
New York,
Whatever intimidating — and hence overpowering — effect questioning by police may have in some circumstances, the judge could find, as he did, that this was not the case with Egan, who was a sergeant in the Brookline police, with twenty-one years of experience. The judge found him to be “strong-minded and intelligent” and could conclude that it was not plausible that Egan’s consent to an examination of the trunk of his car was compelled. His personal characteristics could be taken into account by the judge in assessing whether, in the circumstances, the consent was voluntary.
Schneckloth
v.
Bustamonte,
3. Admissibility of the Stationhouse Statements.
After he discovered the gas can, Lenhart told Egan and his companion, Mellen, that they were suspects in an attempted burning and that there was probable cause to arrest them. No formal arrest was made, but Egan and Mellen were asked to accompany the police to the station for questioning. Egan and Mellen proceeded there in Egan’s car. We may assume that, notwithstanding the absence of a formal arrest, Egan was in a custodial situation. The episode had begun with drawn guns, his car had been searched, he was told he was a suspect. See
Commonwealth
v.
Wallace,
The defendant raises no issue of the voluntariness of the statements. Manifestly a police officer of Egan’s experience understood the Miranda warning and his right to remain silent. It is a right which, indeed, Egan asserted after the first two questions. He was then permitted to leave the police station. The basis for suppression is that he was improperly detained. Cf.
Brown
v.
Illinois,
*665 4. Joinder of the Indictments.
Nine months after Egan was indicted for attempted burning and malicious injury to and theft of a motor vehicle, he was indicted for attempted intimidation of two witnesses in those pending cases. The intimidation charges arose out of complaints by Sheryl Brill, who had for a time lived with Egan, and Leslie Brill Rotman, who was Sheryl’s sister and the owner of the car which Egan was charged with having stolen and attempted to burn. 4

*666 5. Other Assertions of Error.
(a) No objection was made by the defendant’s trial counsel to the prosecutor’s closing argument. Improprieties in the Commonwealth’s closing argument have been asserted for the first time on appeal and the defendant, therefore, is entitled to review only upon a showing that there is a substantial likelihood that a miscarriage of justice will occur.
Commonwealth
v.
Roberts, 378
Mass. 116, 122-123 (1979).
Commonwealth
v.
Harris,
(b) Egan argues that the Commonwealth’s evidence is so thin (he characterizes it as a “house of inferences without a firm foundation”) that he was entitled to required findings of not guilty. We have heretofore reviewed a number of the facts which the jury might have found and it would serve little purpose to rehearse them further. We are satisfied that the evidence was sufficient to enable a rational mind to conclude beyond a reasonable doubt that Egan had committed the crime with which he was charged. Commonwealth v. Latimore, 378 Mass. 671, 678 (1979).
(c) Following the return of verdicts of guilty by a jury, the defendant moved unsuccessfully for a new trial based on newly discovered evidence. The fresh material had to do with the size and kind of barriers which marked the dead-end portion of Greenlodge Street. It was a peripheral subject in the context of the trial as a whole and we can hardly say that the judge abused his discretion in determining that the evidence proffered “was not crucial to the government’s case nor to the defendant’s credibility.” The applicable principles are discussed in
Commonwealth
v.
Markham,
Judgments affirmed.
Order denying motion for a new trial affirmed.
Notes
The Court observed at 417 that the quoted phrases are not self-defining.
We note that Sergeant Lenhart testified that, after giving them Miranda warnings, he told Egan and Mellen they were free to leave the station if they chose not to answer questions. The judge made no findings as to whether permission to leave was in fact communicated to Egan and Mellen.
The former Leslie Brill had married, but her married name apparently did not appear on motor vehicle registration records when the police checked the registration of her car.
Egan had been linked to the Rotman vehicle in other respects. There was evidence that the ignition of the car had not been tampered with, permitting the jury to infer that whoever drove the car to the spot where it was found in Canton had keys to it. There was evidence that the Pontiac had been stolen while outside Leslie’s apartment and that, during friendlier times, Egan had occasion and means to come into possession of a set of keys to Leslie’s car.
The trial of Egan’s companion, Mellen, was severed.
As things developed, the jury acquitted the defendant of the intimidation charges.
