Authorities have identified the man who died in a three-vehicle crash Tuesday night on U.S. Highway 41.
Terrence Siems, 57, of Oshkosh, died as a result of the injuries he received in the crash.
A slow-moving vehicle from Minnesota was traveling south in the far right lane of U.S. Highway 41 near Jacobson Road at 10:35 p.m. when it was rear-ended by another vehicle, which was traveling the speed limit. The second vehicle careened off the highway and stopped on the shoulder of the road. The vehicle from Minnesota, a Ford Focus, was disabled in the lane of traffic, Winnebago County Sheriff's Lt. Gordon Ledioyt said.
Siems was driving a motorcycle south on Highway 41 when he came upon the crash scene. It is unknown why, but the motorcycle could not avoid it and struck the disabled Ford Focus, Ledioyt said.
Siems was taken to Theda Clark Medical Center, where he later pronounced dead, Ledioyt said.
The three lanes of the highway were closed to traffic from 10:30 p.m. until 4:30 a.m. Wednesday while authorities from the Winnebago County Sheriff's Office, Wisconsin State Patrol and Town of Menasha Fire Department investigated.
The crash remains under investigation, but Ledioyt said it doesn't appear alcohol was a factor. No citations have been issued or arrests made.
