Michael Paul Brown, the suspect accused by police of killing four people by opening fire inside a Montana bar has been taken into custody, according to reports by KRTV, KTVH and KPAX . The U.S. Marshals Service previously offered a reward of $7,500 for any information that led to the arrest or capture of the 45-year-old Brown.

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.

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.
