Authorities launched a manhunt for Michael Paul Brown after he allegedly opened fire in the Owl Bar on Aug. 1, killing the bartender and three patrons.

Authorities had been searching for the suspect who shot and killed 4 people last week at a bar in Anaconda, Montana.

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.
