The pistol, wrapped in a polo shirt, had seven rounds in the clip and one in the chamber, a Sandusky police report said.
Officers went to the man’s West Adams Street home and unloaded the gun, then questioned the gardener, who told them he had no idea how the weapon got there.
“We come across these every once in a while,” Sandusky police Detective Gary Wichman said. “Usually it’s someone who panicked after seeing police, and dumped the gun while running.”
Officers ran the pistol’s serial number through a database, which showed the weapon has not been reported stolen.
The gun will sit in evidence for a while before being destroyed.
