Authorities continue a massive manhunt for Michael Paul Brown (45), a US Army and National Guard veteran suspected of fatally shooting four people inside a bar in southwestern Montana. The suspect, who lived next door to the bar, reportedly fled barefoot and shirtless into nearby woods after the attack. Residents have been urged to stay indoors and avoid the area. Brown's family has revealed he struggled with mental illness for years, describing him as a "sick man who doesn't always know where or when he is." His military service from 2001 to 2009 included time in the US Army and MTARNG and officials warn that his training and state of mind make him "armed and extremely dangerous."
