Marquis Costic

Peoria Police are looking for a suspect in a double shooting Sunday that killed a 17-year-old boy.  Police say Marquis Costic is wanted in the shooting at Warren and Butler Streets that left Treyshawn Blakely dead. Police say another unidentified person was shot during the same incident and taken to a local hospital.  Costic is described as a five-foot-seven black male with braided hair. Police say they did NOT recover the semi-automatic murder weapon at his home, but did find other weapons.  Costic is considered armed and dangerous. Anyone with information on the shooting is asked to call the police or Crime Stoppers.  Blakely was the second person in Peoria to die from gunfire the past few days.  Kelsey Coleman, who was 32, was shot to death early Friday in a home invasion.
