Authorities are scouring a mountainous area of western Montana for a military veteran who they say opened fire at a bar, killing four people. 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,

"Residents of the area have been notified and are encouraged to stay inside heir homes and on high alert," Johnson said. Authorities haven't said what led up to the shooting at the bar or a possible motive. Police have identified the four people killed but are not yet releasing their names until they've have had a chance to talk to family members,

A shooting at a Montana bar left four dead Friday, prompting a lockdown in a neighborhood several miles away as authorities searched for the suspect.
