The cops don't know who he is.
He was never reported missing.
He was found on the side of the road.
There is no evidence or clues to anybody left on his clothes or in fingerprints.
Investigators are stumped.
Detectives are stumped.
And the state police and highest of professionals are retorting to the public for help.

All they know of him is what they saw in that digital picture they generated from his body.

And no, No suspects.
