On the evening of February 28, 2013, 26-year-old Courtney Jackson was shot at the Dudley Square MBTA bus station in Boston. Jackson, who was an expectant father at the time, became involved in a verbal altercation with two men, identified as Jamel Bannister and Brian Cooper. As Jackson turned to board a bus around 9:50 p.m., he was shot twice in the back, stumbled onto the crowded bus and collapsed. He was taken to Boston Medical Center and pronounced dead.

Two nearby Boston police officers heard gunfire, observed two men fleeing, and detained them. Surveillance footage reportedly captured the shooting, showing Cooper firing while Bannister stood nearby armed; Bannister was seen discarding a .45 semiautomatic over a fence while fleeing. Investigators described the killing as targeted and connected it to a long-running feud between rival gangs. Cooper and Bannister were charged in Jackson’s death.
