BOSTON (AP) A New York City man charged with fatally shooting a 21-year-old man at a Harvard University dormitory is headed to court.

Jabrai Jordan Copney is scheduled to be arraigned Friday in Cambridge District Court on charges of murder, accessory after the fact to murder and possession of a firearm.

Authorities say the 20-year-old Copney turned himself in to police Thursday night.

Justin Cosby, who lived close to campus but did not attend Harvard, was shot in the abdomen Monday while standing on a stairway leading to a common area inside Kirkland House dorm. He died Tuesday.

Middlesex District Attorney Gerry Leone says Copney was visiting friends at Harvard and that Copney and others confronted Cosby. Leone says Cosby and Copney knew each other.
