At approximately 8 a.m. on Sunday, Multnomah County Sheriff’s Office deputies responded to a report of a body seen along the side of the Historic Columbia River Highway by a passerby just east of the Oneonta Gorge tunnel.
MCSO deputies arrived and located the body of a deceased adult male about 50 yards east of the tunnel. MCSO detectives and the county’s medical examiner were notified.
The highway was closed in both directions for approximately two hours just east of the tunnel while the investigation was conducted.
The body was identified as that of Joseph Holly Kincaid Jr., 49, of Portland. The medical examiner determined the cause of death to be blunt force trauma and the manner of death was ruled accidental.
The area the body was located at along the highway was at the bottom of a steep embankment leading up to a cliff face. The top of the cliff was estimated to be approximately 300 feet.
