MISSION, Ore. -- Umatilla tribal officials are trying to determine if a body pulled out of the Umatilla River near Mission on Friday is a missing Yakama Nation woman.
The body is suspected to be Angela Billy, 41, who has been missing since May 22, according to a news release from the Confederated Tribes of the Umatilla Indian Reservation.
Family members, however, could not positively identify the body, and officials now will turn to dental records and DNA testing to try and confirm the identity, the confederated tribes said. An autopsy is scheduled for Monday.
The body was found by two people on horseback who were conducting a private search for Billy, said confederated tribes Public Safety Director Ray Denny in the release. Tribal police were notified at 6:30 p.m. Thursday by those who discovered the body.
Tribal police and fire personnel responded and were assisted by members of the Oregon State Police Forensics Team, Blue Mountain Drug Task Force and Federal Bureau of Investigation.
The area was accessible only by foot, horse or four-wheelers from one side of the river. The team used wet suits and swift water gear to retrieve the body at 12:30 a.m. Friday, the confederated tribes reported.
Umatilla Tribal Police have been searching for Billy for the past few days after family members filed a missing person report.
Billy is an enrolled member of the Yakama Nation. She also is known as Angela Shippentower and Babette Shippentower.
Because the body has not yet been indentified, police are continuing to ask the public to share any information they have about her possible whereabouts.
