The Lake County Coroner’s Office has identified one of two bodies found in Lake Michigan on Sunday as a Wisconsin man who went missing while swimming in Chicago.

A United States Coast Guard helicopter was conducting a training exercise three miles east of Lake Forest on Lake Michigan around 4:30 p.m. Sunday, according to Lake County Sheriff’s Office Spokesman Lt. Christopher Covelli.

The helicopter spotted the body of an adult male floating in the water. The Coast Guard crew recovered the body, Covelli said.

The man, described as Hispanic, is approximately 5-feet-6 and 180 pounds.

Lake County Coroner Jennifer Banek said on Thursday the body was positively identified as Martin Mendoza, 49, of Waukesha, Wisconsin.

Mendoza was one of two men who went missing after going for a swim near the 63rd Street Harbor in Chicago on August 8.

An autopsy indicated Mendoza died of drowning, Banek said. Toxicology results are pending.

Earlier in the day on Sunday, a fisherman on Lake Michigan spotted a body floating in the water around 3 p.m. approximately three miles southeast of the Waukegan Harbor, Covelli said.

The United States Coast Guard recovered the body, described as an African American female between the age of 18-40.

The woman is approximately 5-feet-4 and 150-170 pounds. She had painted fingernails and toenails and was wearing a summer dress.

A preliminary investigation by detectives suggests the woman was in the water for no more than two weeks, Covelli said.

Detectives and the coroner’s office are actively seeking the identity of the female.

Anyone with any information about her identity is asked to call Lake County sheriff’s detectives at 847-377-4000.
