Officers are "unrelenting in their pursuit, working around the clock" to find him, Montana Gov. Greg Gianforte stressed at a news conference on Tuesday. "Rest assured, our brave men and women of law enforcement aren’t giving up."

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.
