The mother of a middle school boy who attacked a Prince George's County school bus says she’s trying to relocate her entire family, as authorities try to catch the accused 15-year-old gunman. On May 1, three teen boys pushed past a Prince George’s County school bus driver and aide in Oxon Hill and tried to shoot a middle school student in the head, but the gun misfired. Video of the attack shows a teenage attacker holding a gun to the victim’s head and chest while his two accomplices hold the victim down. All three teens then beat the victim and fled. The juvenile attacker with the gun, who authorities have identified only as "Baby K," is also a suspect in the murder of a 23-year-old woman in D.C., according to sources close to the case. Kaijah McCoy was shot and killed on May 3 inside an apartment building on Jamison St. NE. Sources said that she was the sister of one of Baby K's alleged accomplices in the bus attack, who has been caught and charged.
