O’FALLON, MO (KPLR) – One man is in custody after a lengthy police standoff in O’Fallon, Missouri.

The standoff went on for nearly nine hours.

At this point, police are only identifying the suspect so far as a 45-year-old O’Fallon. We’re told he is in custody this morning at police headquarters.

Police fired tear gas and flash bangs into the home where the man had barricaded himself to get him to come out.

This all unfolded on Cordes, just north of I-70 off Main Street. The scene was only about a quarter of a mile from the O’Fallon Police Department.

The man finally surrendered a little before 11 p.m. Sunday night. The call first went out as a domestic disturbance a little after 2 p.m. that afternoon.

When officers arrived, they found the man’s girlfriend outside. She lived at the home where this all unfolded. The suspect lived in the same neighborhood.

Police say the man barricaded himself in the basement of his girlfriend’s home.

Officers sent a canine in to search for the man. They then heard a muffled gunshot and called in the SWAT team. The suspect, who indicated he was armed, eventually released the dog.

There was concern the K9 might have been shot, but we’re told the dog is fine and was not hurt.

After hours of negotiations, as well as the tear gas and flash bangs, the man finally gave up. He was taken to the hospital for treatment of dog bites from the canine.

No gunshots were fired.

O’Fallon Police Chief Roy Joachimstaler said the man was wanted on a warrant from another area and likely did not want to go back to prison. We understand that warrant is for some kind of felony out of the Warrensburg area. Police said the man could face charges, including domestic assault and possible weapons violations.
