Oglala Sioux officials have identified a man fatally shot during a basketball tournament on the Pine Ridge Indian Reservation, and they’re taking steps to boost safety after a string of homicides.

Tribal authorities said several unidentified assailants killed Vinnie Brewer Sunday afternoon in the parking lot of the SuAnn Big Crow Center Boys and Girls Club.

Neither the tribe nor the FBI has released details. Police are creating an anonymous hotline for people to call with information on Brewer’s killing or on other recent reservation homicides.

On Facebook, police said martial law will not go into effect on the reservation and urged the public to continue with their daily lives. Curfew hours for those younger than 18 are 9 p.m. on school nights and 10 p.m. on other nights. Accompanying a parent or being at an organized activity are two exceptions to the curfew.

Tribal officials have asked the Bureau of Indian Affairs to send more officers to the reservation on a temporary basis, and the tribe’s police department is looking to add 20 more officers. A drug task force also might be created.
