Four people were killed in a shooting at a Montana bar and law enforcement are searching for a suspect described by his niece as a former U.S. soldier who struggled to get help for mental health probl

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.

The search for the suspect continued in the mountains just west of Anaconda, where he is accused of fatally shooting four people, officials said.
