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.

Police are scouring mountains for an armed military veteran after four people were killed in a shooting in a Montana bar.
