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.

Michael Paul Brown, 45, fled the Owl Bar in the town of Anaconda in a white pickup truck but ditched it at some point, said Lee Johnson, administrator of the Montana Division of Criminal Investigation, which is overseeing the case. He urged residents late Friday to stay at home and remain on high alert.

Parts of a national forest near Anaconda, Montana, were closed late Saturday as authorities expanded their search for the gunman accused of killing four people at a bar on Friday morning.
