Boston Man Convicted In 2013 MBTA Station Shooting Of Courtney Jackson

A second person has been convicted in the shooting of a Boston man killed as he boarded a bus.

Jamel Bannister was convicted Tuesday in Suffolk Superior Court of second-degree murder in the February 2013 slaying of Courtney Jackson at the Dudley MBTA station.

Prosecutors say Bannister and Brian Cooper got into an argument with Jackson, who had just gotten off one bus and was boarding another. Video surveillance showed Cooper pulling a gun and shooting Jackson, while Bannister can be seen trying to pull something from his pocket, which prosecutors believe was a gun. A handgun was found nearby.

Cooper was previously convicted of second-degree murder.

Bannister is scheduled to be sentenced Wednesday.

Bannister's attorney said his client did not know Cooper and had nothing to do with the shooting.
