BOSTON -- A former Harvard University student has been indicted in connection with the May 2009 shooting death of Justin Cosby, 21, of Cambridge, Middlesex District Attorney Gerry Leone said.

Brittney Smith, 22, of New York City, was indicted by a Middlesex Superior Court grand jury Tuesday on charges of illegal possession of a firearm, accessory after the fact, willfully misleading a grand jury and willfully misleading a police officer.

Smith will be arraigned Tuesday in Middlesex Superior Court.

According to authorities, on May 18, 2009 at approximately 4:48 p.m., the Harvard University Police responded to Kirkland House, a dormitory at Harvard College, located on Dunster Street in Cambridge on reports of shots fired.

Cosby, suffering from an apparent gunshot wound to the abdomen, had left Kirkland House and ran to the intersection of Dunster and Mount Auburn streets, where he collapsed.

He was taken to Beth Israel Hospital and was pronounced dead.

Investigators said that three men from New York City, Jabrai Jordan Copney, Blayn Jiggetts and Jason Aquino, none of whom were students at Harvard University, arranged for a meeting with Cosby for the purpose of robbing him during a drug deal. During the meeting with Cosby in a common area inside Kirkland House, multiple shots were fired, including one that killed him, officials said.

Officials said that Smith, a student at Harvard at the time of the shooting who invited Copney to campus, gave her Harvard-issued ID, which works as an electronic key card, to the men so they could enter the building. After the shooting, police said Smith hid the gun under a friend's bed, unbeknownst to the friend. Smith then fled the campus area with Copney, Jiggetts, and Aquino and returned to New York City with them on a bus from Boston that evening.

Prosecutors said Smith returned to Massachusetts with Copney the next day and, when she returned to Harvard where she was questioned by university police about her ID card, she lied to them, telling them that she had the pass key in her possession the entire time. Copney, 20, of New York City, was charged with murder, accessory after the fact to murder and possession of a firearm. He was ordered held without bail.

Jiggets, 19, also known as Bliz, of Mount Vernon, N.Y., was charged with first degree murder, accessory after the fact of murder, armed robbery and possession of a firearm. He was ordered held without bail.

Aquino, 23, of Manhattan, was charged with first degree murder, accessory after the fact of murder, armed robbery and possession of a firearm. He was ordered held without bail.
