Police have identified a suspect in connection with a weekend homicide.
Police are looking for Marquis Costic, 22, whose last know address was 1614 West Butler.
Treyshawn Blakely, 17, was found dead Sunday night in the 1600 block of West Butler. He had been shot in the head with a .223 caliber semi-automatic rifle. Another person was wounded.
A search of Costic's house turned up other weapons, but not the one believed used in Sunday's shooting.
Police say Costic should be considered armed and dangerous.
Costic is described as a black man, 5-foot-7, 135 pounds with black and brown hair in braids.
Anyone who know Costic's whereabouts is urged to call Peoria police or Crimestoppers at 673-9000.
