Michael Paul Brown, 45, fled The Owl Bar in the small town of Anaconda in a white pickup truck but ditched it at some point, said Lee Johnson, administrator of the Montana Division of Criminal Investigation, which is overseeing the case. He urged residents late Friday to stay at home and on high alert.

Four people were killed in a shooting at a bar in Anaconda in western Montana, according to the Montana Highway Patrol. The shooting suspect, Michael Paul Brown, is at large and believed to be armed and dangerous, the Anaconda-Deer Lodge County Law Enforcement Center said.

A suspect is on the run after multiple people were shot in the US state of Montana, authorities say. The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) said it was "responding to a shooting where multiple parties have been shot at a business in Anaconda, MT".
