Juneau police are working to identify remains found near a Mendenhall Valley road Monday, with few details about the discovery immediately available.

A duck hunter was told of the discovery, at a campsite near Rainbow Row at the base of Thunder Mountain, at about 4 p.m. Monday according to JPD spokesman Lt. David Campbell. Detectives hiked about 40 minutes from the local trailhead to the site, where they discovered “partial remains of what appeared to be one person.”

“The condition of the remains showed considerable deterioration and prevented identification, including a determination of gender,” Campbell wrote. “It was also not possible to determine how long the remains had been in the woods.”

Campbell wasn’t available for further comment on the remains Tuesday.

Police sent the remains to the state medical examiner’s office to determine their identity and cause of death.
