State police say they're investigating multiple police officers involved with the shooting death of an armed man at a tavern in Lincoln.
Lincoln officers responded to a 911 call around 11:30 p.m. Tuesday night at the Glass House Tavern. Officials say 62-year-old Donald Letterle was fighting with a woman at the bar.
Police say he had a firearm, so they "engaged" Letterle -- apparently shooting and killing him.
Illinois State Police Master Sergeant Eric Hall says he can't say how many Lincoln officers were involved.
