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.

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.

Montana Division of Criminal Investigation administrator Lee Johnson says 45-year-old Michael Paul Brown fled The Owl Bar after the Friday shooting in the small town of Anaconda.
