A New York man was arrested by Cambridge police this evening and will be charged with the murder of Justin Cosby, a 21-year-old who was shot in the basement of Kirkland J entryway Monday evening.
Jabrai J. Copney, 20, turned himself in to authorities at the Cambridge Police Station earlier this evening and is expected to be arraigned on Friday in Cambridge District Court, according a statement from a spokesman from the District Attorney's office of Middlesex County.
Wednesday evening, The Crimson reported that Cosby has been linked to drug sales to Harvard students.
The district attorney's office said that the defendant was visiting friends on campus. It is alleged that, along with others, Copney then confronted Cosby in a common space in Kirkland House. Shots were fired, and one of those shots struck Cosby, resulting in his death, according to the DA.
The DA's office also said that an investigation has determined that the victim and Copney were known to each other.
