RAPID CITY, S.D. (AP) — Oglala Sioux tribal police and the FBI say they are investigating a triple homicide near Manderson, SD. The FBI says two men and a woman were fatally shot in the early morning hours last Wednesday at a home in Wounded Knee on the Pine Ridge Indian Reservation. Officials say a person of interest is in custody and is being held on unrelated charges.

The victims have been identified as 39-year-old Michael White Plume Sr., James Graham, and Alma Garneaux, both 38. An online obituary says Garneaux was the mother of seven children.
