At the trial of the defendant on an indictment charging him with murder in the first degree the jury returned a verdict of guilty with a recommendation that the death penalty not be imposed. G. L. c. 265, § 2. All proceedings were subject to G. L. c. 278, §§ 33A-33G, inclusive. The case is before us on the defendant’s appeal which is accompanied by a summary of the record, a transcript of the evidence and the assignments of error. The only assignment of error relied upon and argued before us is the denial of the defendant’s motion for a directed verdict of not guilty of murder in the first degree. 1
The question presented is whether the evidence in the case supported the verdict of murder in the first degree. Some facts are not in dispute. The defendant admits that about noon on November 6, 1963, he, in concert with one Yasaian, now deceased, 2 both armed with guns, assaulted with intent to rob certain persons in a jewelry store located on the floor above the street level in the Dexter Building, 453 Washington Street, Boston. It is not disputed that Yasaian, in circumstances later to be narrated, shot and killed George J. Holmes, a Boston police detective in plain clothes. It is not disputed that the killing of Holmes by Yasaian was murder.
*527 The evidence, which included testimony by the defendant, tended to show the following. The defendant and Yasaian had known each other for about six years. They had been “partners” in “deals” before. The defendant expected to share in the “loot of this deal.” By pre-arrangement the defendant and Yasaian met at a restaurant on Charles Street, Boston, about 10:30 a.m. on November 6, 1963, where they talked. When they left the restaurant each had a seaman’s knitted watch cap and a nylon stocking. Both were armed. The defendant had two automatic pistols of different calibers. The smaller of the two weapons was concealed in his underwear. Both weapons were fully loaded, i.e., there were seven bullets in the magazine and one bullet in the firing chamber of each weapon. Yasaian had an automatic pistol which was similarly loaded. The defendant, in addition, had on his person a box containing forty-two bullets. The defendant knew that all weapons were fully loaded, capable of firing, and ready to fire.
The two men walked from the restaurant to the Dexter Building where they arrived around noontime. They went up the stairs and, when at the top, drew the nylon stockings over their heads, put on the watch caps, and then, with drawn guns, entered the jewelry store. Yasaian went to the left toward a counter where some customers and employees were standing and said, “This is a holdup, stand still everybody.” Simultaneously the defendant, crouching down to avoid observation through the window by people in a department store across the street, proceeded directly to the diamond room where an employee and a customer were talking. He ordered them to leave the room, saying, “I’ll blow your brains out.”
In the meantime, Officer McGrail of the Boston police was directing traffic at the intersection of Washington and Summer streets. He was talking with Detective George J. Holmes. McGrail saw Sergeant Chennette coming along Washington Street in a patrol car.
The alarm in the jewelry store sounded.
Dellelo, still in a crouched position in the diamond room, *528 jumped up and yelled, “It’s gone off, let’s beat it.” 3 Both men dashed for the stairs, Dellelo in the lead, removing the nylon stocking and cap as he ran. When he reached the door leading out of the building, he ran into Officer McGrail who had responded to the alarm. Dellelo poked a gun into McGrail’s stomach, then drew back and kicked him in the groin. He ran along Washington Street in a northerly direction, turned left on Winter Street, and ran as fast as he could up Winter Street, pointing the gun at the crowd to make them move out of his way. He was pursued by Sergeant Chennette and Officer McGrail.
Yasaian ran from the building, turned in a southerly direction on Washington Street and encountered Holmes at a point thirty-four feet from the doorway of the Dexter Building. Holmes, who had a shopping bag in one hand and nothing in the other, raised his arms to shoulder level and said, “Stop.” Yasaian stopped “for a split second,” looked at Holmes, drew his gun from his jacket, took direct aim at Holmes and shot him. He shot him twice more. He pushed Holmes who fell bleeding to the street. Yasaian then resumed his run in a southerly direction on Washington Street and disappeared in the crowd.
Sergeant Chennette and Officer McGrail captured the defendant at gunpoint at the intersection of Winter and Tre-mont streets, where after having been tripped by a bystander, he had entered a cab and “put the gun to the side of . . . [the driver’s] face.” The defendant and the pursuing officers heard the sound of three shots as they ran up Winter Street.
The autopsy disclosed that Detective Holmes died from a gunshot wound of the chest, with massive internal bleeding. There were also two entrance wounds in the back of his left shoulder.
The defendant contends that on the foregoing evidence he was entitled to a directed verdict of not guilty of first
*529
degree murder. As already noted he concedes that the killing of Holmes by Yasaian was murder. He could scarcely do otherwise on any theory of law in the light of the discussion and holding in
Commonwealth
v.
Lussier,
We consider the first of these contentions. Whether the attempted crime was completely over, so as to make inapplicable the third clause of G. L. c. 265, §

is a question of fact, to be looked at objectively, and its beginning and end are marked by what is done, rather than what is thought.
Commonwealth
v.
Green,
The defendant argues further that, since the shooting of Holmes did not occur on the premises where the attempted robbery took place, as it did in
Commonwealth
v.
Green,
The remaining contentions of the defendant are based upon his own testimony and require only brief discussion. The defendant testified that before he entered the store he had said to Tasaian, “Hey, wait a minute, I don’t want any shooting. I don’t want to get involved in no shooting,” and that upon the sounding of the alarm, he had yelled, “I . . . [don’t] want any part of this action, I am bailing out.” For one thing the jury were free to disbelieve that the defendant made either of the statements. For another, as to the first alleged statement the law is clear that “it is no defence for . . . associates engaged with others in the commission of a robbery, that they did not intend to take life in its perpetration, or that they forbade their companions to Mil.”
Commonwealth
v.
Devereaux,

*532
387, 392. The second alleged statement, if made, raised questions of fact whether the statement showed a determination by the defendant to go no further with the whole criminal enterprise and also whether it effectively communicated that determination to Yasaian in sufficient time to permit Yasaian likewise to abandon the undertaking before the shooting of Holmes took place.
Commonwealth
v.
Snyder,
The motion for a directed verdict was properly denied.
Judgment affirmed.
Notes
At the same trial the defendant was found guilty of the following crimes arising from the events of November 6, 1963; conspiracy to rob, carrying a firearm without a license, assault by means of a dangerous weapon, assault and battery and assault with intent to rob while armed.
Yasaian took his own life on November 11, 1963, while still at large.
There were minor variations in the testimony of witnesses as to the words used by the defendant. The defendant’s own testimony as to the words he used is discussed later in this opinion.
