A 66-year-old woman pulled from the water Saturday in north suburban Round Lake Beach has died.

About 3:10 p.m., officers responded to 911 calls after the woman was pulled from the water at Lakefront Park by another swimmer and the on-duty lifeguard, Round Lake Beach police said.

The lifeguard gave CPR to the woman, police said. First responders took over CPR and she was rushed to Condell Hospital in Libertyville in critical condition, police said.

She died that night at 9:46 p.m., police said.

An autopsy was done, but preliminary results haven’t been released as toxicology results and other tests are pending, the Lake County coroner’s office said.

Police said the woman was from Mexico and visiting relatives in Wheeling and Round Lake Beach. Police initially said she was 76 years old and from Wheeling.

The incident remains under investigation, police said.
