the started taking out the 104 year old Ballville Dam in Fremont / Sandusky Ohio, and when the water level lowered, found a truck in the water 1/2 mile upstream that was last registered in 1996 (thanks Marc!)

Divers searched the vehicle, but found nothing inside, according to Sandusky County Sheriff Chris Hilton.

Hilton said they could not learn much about the vehicle because its Ohio license plate, from 1996, was too old to search on their database.

He said they are investigating how the vehicle got there, but it could have been there for at least 21 years.
