Police in New Jersey say a fisherman discovered a lone shoe on the beach — with a severed foot inside.

The gruesome discovery was made around 1 p.m. Tuesday in Ocean City, WCBS-TV reported.

Police released a photo of the sand-crusted black Adidas high top shoe on Wednesday with the hope that it could be identified. The shoe is a size 5 1/2. The remains were a right foot.

The foot will be sent to a state lab for testing.
