PORTERVILLE, Calif. (AP) — Authorities in California have confirmed a fifth death in a shooting of tribal members on an Indian reservation.

Tulare County sheriff’s spokeswoman Chris Douglass says Sunday that an 8-year-old girl is among four family members killed by her father. She was identified as Alyssa Celaya.

Authorities say 31-year-old Hector Celaya also killed his mother and her two brothers and wounded Alyssa’s brother and sister, then died in a shootout with police.

Authorities have not disclosed what motivated Celaya to kill his relatives, who live on the Tule River Indian Reservation in central California. Tribal members on the remote reservation said he had a troubled past.
