The man was identified as William Kasper of the 18400 block of Gottschalk Avenue in Homewood, according to the Cook County medical examiner's office. An autopsy is scheduled for Tuesday.
Homewood Fire Department learned a person had fallen through the ice at 3:33 p.m. at the Izaak Walton Nature Preserve in Homewood's northeast corner and immediately put out a call for a dive team, according to a prepared statement from the department.
But two firefighters who arrived at the preserve before the dive team pulled the man out from 10 feet of water and immediately began resuscitation and advanced life support. The firefighters reported seeing a hat, cane, and articles of clothing near an opening in the ice, and a loose dog near the area.
Glenwood Fire Department paramedics transported the man to the hospital.
The Izaak Walton Nature Preserve consists of 193-acres of lakes, forest, ancient sand dunes, native prairie, walking trails, Scout facilities, and picnic grounds. It operates independently from the Homewood-Flossmoor Park District.
