The seven boaters were returning to shore about 4 a.m. when their boat hit a breakwall and capsized, police and Chicago Fire Department Chief Juan Hernandez said.

Hernandez told the Chicago Sun-Times that a woman who was about 20 did not survive after the boat capsized near Chicago's "Playpen" area, where boaters frequently gather near the shoreline.

Chicago police said the search for her body had to be suspended because of bad weather but would resume later Friday.

The six other boaters, between the ages of 20 and 30, were rescued from the lake and taken to hospitals. Chicago police said the four women and two men were all reported to be in fair condition.
