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.

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.

Investigators searching for a man they say shot and killed four people at a Montana bar Friday morning have located the vehicle he fled in, but the suspect remains on the loose, officials said.
