Divers returned to West Loon Lake in Antioch this morning to search for a 62-year-old man who jumped into the lake as he and another man were boating, officials said.
The missing man was with a 69-year-old man on a pontoon boat Thursday afternoon when the younger man decided to go swimming, said Lake County sheriff's spokeswoman Sgt. Karen Kates.
He had trouble getting back into the boat and the 69-year-old man jumped in to help him, but neither man was able to get back into the boat, according to Sgt. Karen Kates, a spokeswoman for the Lake County sheriff's office. A passing boat was able to rescue the 69-year-old man, Kates said.
Crews from the Antioch Fire Department, along with about 40 divers from numerous other Lake County fire departments searched until evening.
The lake is near Grass Lake Road and Illinois Route 83, said Kates.
