“We had to deploy two divers in order to facilitate the rescue, because of the way he was wedged into the rocks inside the water there just off of the shore here,” said Fire Department diver Reuben Zendejas.

Shortly after 11 a.m., Fire Media said the man was taken out of the water by fire department divers and taken to Weiss Memorial Hospital in critical condition.

The Cook County Medical Examiner’s office said the man was in his 50s, but had not released his identity as of Sunday evening. He was pronounced dead at 4:35 p.m. Sunday.
