A black ex-con fatally shot his girlfriend's teenage son, then killed one person and injured another on a bus in Queens during a 15 minute shooting spree

African-American Damel Burton, 34, told police that the bus shooting occurred because he believed the commuters were plotting against him. Police say that the spree began when Burton, who spent seven years in prison for armed robbery, got into an argument with 18-year-old Keith Murrell and shot him in the chest in the Queens apartment that they shared with Sheen Tucker, Murrell’s mother and Burton's girlfriend. Keith was able to leap out of the window of his room and run to a nearby Royal Fried Chicken store to get help. He collapsed outside the chicken joint and later died at Jamaica Hospital. “I had to settle a beef,” Burton later told police of that shooting. Burton meanwhile got on a bus less than 15 minutes after that shooting, where he became increasingly unhinged. He randomly shot commuter Marvin Gikes, 36, in the back of the head — Gikes collapsed on the bus’ rear steps and died. Then he shot commuter Jojuan Lipsey, 29, in the face as passengers started screaming. Burton ran off the bus and was caught less than a block away by police still carrying a semi-automatic 9-mm. Ruger pistol. He has been charged with second-degree murder, gun possession and assault.
