Missing U.S. Navy service member found in Waukegan Harbor died from drowning, autopsy determines

An autopsy released Thursday determined that a missing U.S. Navy service member found in Waukegan Harbor died from drowning, officials said.

The body of 18-year-old Seamus Gray, reported missing March 21, was found in the harbor Wednesday evening, according to Waukegan police.

Preliminary autopsy results indicate Gray died from drowning and there was “no evidence of significant injury which would have contributed to his death,” according to Lake County coroner’s office.

Police were conducting a traffic stop about 7 p.m. near the harbor when they were flagged down by utility workers who said they saw what they thought was a body in the water.

Gray was last seen on video leaving a bar on Genesee Street in Waukegan about 1:40 a.m. March 18, police have said.

The incident remains under investigation by Waukegan police, the U.S. Naval Criminal Investigative Service and the Lake County coroner’s office.
