SOUTH ROXANA, Ill. (AP) — A southern Illinois police chief says he’s asked state police to investigate an overnight incident in which an officer shot and wounded a man following a disturbance.

South Roxana Police Chief Bob Coles tells the St. Louis Post-Dispatch that the man is expected to survive. But he declined Wednesday to release details of the events that preceded Tuesday night’s shooting along the northern edge of South Roxana in an area east of Highway 111.

The chief said Wednesday that everything he’s seen so far tells him the shooting was justified but he’s asked the Illinois State Police to investigate the shooting.
