Mentor police are trying to learn more about who a mystery debris at the intersection of State Route 306 and Tyler Blvd last week.
A photo snapped by the Mentor Fire Department on April 14 showed two cars stuck in what police described as a gray muck, or gray mud-like material.
Now police are releasing a new photo showing the truck that was possibly involved in the dumping.
The photo shows a semi-tractor trailer with a green cab.
Anyone with information on the owner or operator of the truck in the photograph is asked to contact the Mentor Police Department at 440-205-3293.
