A single vehicle accident in the town of Pensaukee yesterday has left a Manitowoc area man dead. The unnamed 58 year old was the only person in the vehicle, and was found unresponsive just off of U.S. 41 near Brookside just after 8:00 AM. The cause of the accident remains unknown at this time, but alcohol and speed do not appear to be factors in the incident. The investigation remains ongoing. The Oconto County Sheriff’s Department was aided on the scene by the Wisconsin State Patrol, and emergency Services from Oconto Fire and Rescue and Pensaukee Fire Department.
