KANSAS CITY, Kan. (AP) — A man who dropped a loaded handgun inside a Kansas City school auditorium last year has been sentenced to nearly two years in prison for being a felon in possession of a firearm.

The Kansas City Star  reports 42-year-old Larry K. Wren, 42, was sentenced to 21 months in prison Monday. According to court documents, Wren was attending a concert at University Academy when he accidentally dropped the weapon on the auditorium floor. The documents say another concertgoer saw Wren pick up the handgun.

According to the documents, Kansas City police located a 9 mm handgun with 15 rounds in a purse inside a car in the school’s parking lot. Authorities said Wren told police he had forgotten the gun was with him and had a woman take it outside.
