Law enforcement officers are scouring a mountainous area of western Montana for a military veteran who authorities say opened fire at a bar, killing four people.

A shooting at a Montana bar left four people dead Friday, prompting a lockdown in a neighborhood several miles away as authorities searched for the suspect in a wooded, mountainous area. The shooting happened around 10:30 a.

The search for Michael Paul Brown, the suspect in the deaths of a bartender and three patrons at Owl Bar, continued into the weekend. Authorities have warned that he is armed and dangerous.
