Witnesses say the two were playing basketball in on the courts at the borough's Memorial Park at about 5 p.m. when they were shot. Carlisle Police, state police and investigators from the Cumberland County District Attorney's office were seeking four suspects, all believed to be from the New York area, in connection with the murder.
Police say they are all black men.
Carlisle Mayor Kirk Wilson said Banks and Anderson were playing basketball when they were approached by two of the four suspects. He said a short, heated argument took place. One suspect allegedly drew a gun from his waistband and fired more than six shots, at least one of which hit Banks, Wilson said. Anderson was also hit during the gunfire. Despite his injuries, he left the scene without assistance.
