FERGUSON • St. Louis County police said they are searching for an AR-15 rifle swiped from one of the two St. Louis County police cars set ablaze during Monday night's violence.

Sgt. Brian Schellman said rioters who torched a county police car about 10 p.m. in the 400 block of South Florissant Road yanked out the high-powered police rifle and the rack in which it was stored. At least one other county police car was set on fire Monday night.

The rifle was still missing late Wednesday night. Schellman said the rifle is the only county police weapon taken since protests and violence erupted after Monday night's announcement of the grand jury's decision in the Michael Brown shooting.

Police said 10 police cars were damaged or destroyed Monday night. Rioters caused serious damage to a Ferguson police car Tuesday night.
