Oregon State Police investiging the cause of a critical injury pedestrian-involved traffic crash Sunday evening along Highway 20 near Eddyville. The pedestrian was reported naked and acting erratically along the highway prior to police and medical personnel arriving.

Sunday around 7:25 p.m., OSP and Lincoln County Sheriff's Office received a report of an erratically acting naked man in the roadway along Highway 20 near milepost 29. Shortly after the first report, another call was received that the naked man was involved in a collision with a vehicle. When medical personnel and a LCSO deputy arrived on scene, the man, identified as Amos McLean, age 38, from Eddyville, was critically injured and transported by PACWEST ambulance to Good Samaritan Regional Medical Center in Corvallis for treatment. McLean is reportedly in critical condition and any factors of the reason for his behavior is not known.

Witness information indicates McLean was moving around naked in the center of the highway, waving branches, and shouting. He then entered a neighbor's vehicle, removed a box of mail and moved to the center of the westbound lane where he sat down. As vehicles approached and stopped, McLean got up and approached a Ford F250 pickup pulling a travel trailer driven by Ron Simpson, age 57, from Salem, and then attacked the side of the pickup, throwing his body against it and punching the side.

As Simpson pulled forward and away from the erratically acting man, the travel trailer collided with the McLean knocking him to the pavement.
