The Manitowoc County coroner says there are no signs of trauma to the body of a man found in Lake Michigan at the Manitowoc harbor.

Coroner Curtis Green says the cause of Jesse Neuser's death is pending further tests. Green says alcohol may have contributed to the death of the 24-year-old man found in the lake Sunday.

WOMT radio reports authorities say Neuser was not reported missing and had been in the lake less than 36 hours.
