ST. LOUIS (KMOX) - The Jefferson County Sheriff's Office says it is investigating an officer-involved shooting that took place overnight.
According to the Jefferson County Sheriff's Office, at 9:30 p.m. Monday, deputies were dispatched to a home in the 8100 block of Old Highway 21, north of Hillsboro, for a report of a man banging on the home's door.
When deputies arrived, the man, who identity has not yet been revealed, pointed a handgun towards his head. Additional units were called for assistance, and some with crisis intervention training. It would lead to a three-hour standoff.
