Authorities said on Sunday that the search for the man accused of killing four people at a Montana bar on Friday morning has expanded. Beaverhead-Deerlodge National Forest said that more than 16 square miles of parkland is closed through Aug. 16 to facilitate the search for the suspect, Michael Paul Brown, 45. Brown is a former U.S. Army soldier who allegedly gunned down a bartender and three patrons at the Owl Bar next door to his Anaconda home. Knudsen identified the shooting victims as 64-year-old Nancy Lauretta Kelly, who was the bartender at the time of the shooting; 59-year-old Daniel Edwin Bailey; 70-year-old David Allen Leach; and 74-year-old Tony Wayne Palm. However, a picture released Saturday by the Montana DOJ showed him fleeing the scene, apparently stripped down to just his boxers.
