The suspect, 45-year-old Michael Paul Brown, lived next door to the bar, public records show. Authorities said a SWAT team cleared his home, and he was last spotted in the Stump Town area, just west of Anaconda. The massive manhunt continued into Friday evening in the wooded, mountainous area.

A manhunt is underway after a deadly shooting inside a Montana business on Friday. Four people were killed at The Owl Bar in Anaconda, according to the Montana Division of Criminal Investigation. Police identified Michael Paul Brown, 45, as the suspect.

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