A manhunt in western Montana extended into Saturday as authorities searched for a suspect they believe fatally shot four people a day earlier at a local bar and who they said remained armed and dangerous.

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.

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