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, officials said.

Authorities found a truck used by a suspect in the shooting deaths of four people at a bar, the bartender and three patrons, in a small town in western Montana.

The search for the suspect, identified as Michael Paul Brown, continued into the weekend. Authorities have warned that he is armed and dangerous.
