A 25-year-old Wisconsin woman died early Friday after firemen pulled her from Lake Michigan on the South Side.

Emergency personnel responded about 2 a.m. to a call of a person in the water near Oakwood Boulevard and the lake, Chicago police said.

Divers from the Chicago Fire Department pulled Jacqueline Zaquita Thomas from the water and took her to the University of Chicago Medical Center, where she was pronounced dead, police and the Cook County medical examiner’s office said.

An autopsy Saturday found she died from drowning, and her death was ruled an accident, the medical examiner’s office said. She lived in Racine, Wisconsin.

Detectives were conducting a death investigation.
