Amid an ongoing manhunt Montana authorities warned the public Sunday that Michael Paul Brown, the suspect accused of killing four people in a Montana bar on Friday morning, could return to Anaconda, the town where the shooting occurred at the Owl Bar.

Those killed on Friday were a bartender and three patrons, ranging in age from 59 to 74, the authorities said. The suspect fled into the nearby foothills.

Authorities urged residents to stay inside and on high alert because they consider Michael Paul Brown armed and dangerous.
