Donald R. Letterle, a 62-year-old white man, was shot and killed by a Lincoln police officer on April 22, 2014, at The Glass House Tavern in Lincoln, Illinois. Earlier that evening Letterle and 38-year-old Candi Gesner, who had been in an on-and-off relationship for about two and a half to three years, got into a heated argument at the bar. Letterle left but returned armed with a handgun; the bartender, Tina Baker, called police.

Officers arriving at the scene found Letterle still holding the weapon and involved in a physical altercation with Gesner. Repeated commands to drop the gun were reported; Letterle did not comply and was shot by a Lincoln officer. The Illinois State Police conducted an investigation into the officers’ actions, and those findings were to be reviewed with the Logan County State’s Attorney.

What details about that night, or about Letterle and Gesner’s relationship, might help fill gaps in the timeline leading up to the shooting?
