Three months after Cambridge resident Justin Cosby was shot to death in the basement of Kirkland House in what prosecutors say was a failed “drug rip” (he was found with $1,000 and one pound of marijuana near his body, and The Crimson later reported that he may have been involved in drug sales to Harvard students), police have apprehended all three suspects they believe were involved in the shooting.

The three men, all from New York, are currently jailed without bail.

Jabrai J. Copney, 20, was the first to be arrested and arraigned after he turned himself in to police in late May. He’s since been indicted on five charges including first-degree murder, and he pleaded not guilty to all the charges. Police say that Copney, an aspiring songwriter, pulled the trigger on Cosby.

Blayn “Bliz” Jiggetts, 19, was arrested in Harlem in early June and is the second man to be apprehended by police. He was arraigned in Manhattan over the summer but refused to return to Massachusetts voluntarily to face charges, which also include first-degree murder. Prosecutors have thus far failed to obtain the warrant needed to extradite Jiggetts to Massachusetts.

Jason Aquino, 23, was the final suspect to be arrested by police in connection to the shooting and faces the same charges as Jiggetts. In late July, he was arraigned in Manhattan and extradited to Cambridge, where he pleaded not guilty to all the charges.
