The former U.S. Army soldier accused of gunning down four people at a Montana bar has been captured following a weeklong manhunt.

Michael Paul Brown, 45, is accused of killing a bartender and three patrons at the Owl Bar a week earlier on Aug. 1.

State authorities have not said what sparked last week’s shooting, which left a female bartender and three male patrons dead. The victims were identified as Nancy Lauretta Kelley, 64; Daniel Edwin Baillie, 59; David Allen Leach, 70; and Tony Wayne Palm, 74.
