The man had gray hair and appeared between 55 and 70 years old, Borkovich said. He said the autopsy found no signs of foul play. Michigan State Police officials will let investigators use a portable fingerprint scanner, but that will only yield an identification if the man was fingerprinted before, he said.
Borkovich hopes the mans clothing which he considered very odd for summer could yield some tips to the identity. The man wore black sweatsuit pants with two white stripes down the legs, a black jacket with white stripes on the sleeve cuffs and white high top tennis shoes.
The man also had his hood up a potential clue about weather conditions at the time he went into the water, Borkovich said.
