The body of a woman reported missing on the Warm Springs Indian Reservation was discovered Friday morning, and two women have been arrested in connection with her disappearance.

Tribal member Faron Kalama, 30, was last seen several days ago, the FBI announced in a statement late Thursday. Friday, the agency announced her body had been found in a remote area of the reservation.

Tana Lawrence and Angeledith Kalama are being held in the tribal detention facility on charges of assault and battery, kidnapping and sexual assault. FBI spokeswoman Beth Anne Steele said ages for the two women, both tribal members, were not immediately available, and that it was not clear if Faron Kalama and Angeledith Kalama are related.

The state medical examiner will perform an autopsy, and results are expected early next week.

Investigators do not believe there is any connection between the disappearance and death of Faron Kalama and the death of Jonas Andrew Miller, whose body was found on the reservation earlier in the week and whose death is being investigated as a homicide by the FBI and the Warm Springs Police Department. No arrests have been made in connection with Miller’s death or disappearance.

Warm Springs Public Safety Manager Stan Suenage did not return a call seeking comment.

Steele said federal charges could be brought against the two women arrested Friday, but that the charges filed in tribal court will proceed first. The case is still under investigation, she said.
