Four people were killed in a shooting at the Owl Bar in Anaconda, Montana on Friday morning, and the suspect, 45-year-old Michael Paul Brown, remains at large.

Authorities say Brown opened fire around 10:30 a.m. and then fled, prompting a manhunt involving SWAT teams and the FBI.

He was last seen driving a white 2007 Ford F-150 and is considered armed and dangerous.

Police are searching wooded areas near Stumptown Road, the U.S. Sun has reported.

Brown reportedly lives next to the bar, and the victims have not yet been identified.
