Linn County Sheriff's officials are investigating the discovery of possible human remains on Monday, April 6.
County Sheriff Jim Yon said his office received a call at 4:58 p.m. Monday regarding the discovery, in the 41000 block of Upper Calapooia Drive.
The remains were located approximately a mile from Upper Calapooia drive in a very densely forested area by hikers. Weyerhaeuser assisted the investigation by clearing an overgrown road to make access to the area easier.
"We have tentatively identified the remains connected with a 2011 missing persons case," Yon said. "We are working with the State Medical Examiner's Office to confirm the identity and cause of death. There is no further information at this point."
Linn County Search and Rescue assisted with the investigation.
The discovery was the second of what is believed to be human remains in Linn County within the past week.
