NYC Man Pleads Guilty in Harvard Shooting

One of three New York City men accused of shooting to death another man in a Harvard University dormitory in Cambridge, Mass., has pleaded guilty to a lesser charge of manslaughter in exchange for his cooperation.

Middlesex District Attorney Gerard Leone says 21-year-old Jason Aquino also pleaded guilty Thursday to armed robbery and willfully misleading a grand jury. Sentencing is set for May 2.

Co-defendant Blayn Jiggetts has testified he, Aquino and Jabrai Jordan Copney went to Harvard in 2009 to steal drugs from 21-year-old Justin Cosby. He says Copney shot Cosby. Copney has pleaded not guilty.

A fourth defendant, Brittany Smith, was a Harvard student and is Copney's former girlfriend. She has pleaded not guilty to hiding the gun used in the slaying and to helping the three men elude authorities.
