The suspect accused of fatally shooting four people at a Montana bar, who remains at large, struggled with mental health issues but was denied services from agencies that were supposed to help, according to his niece.

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.
