Heat kills 1 at Chicago Marathon

CHICAGO - A Michigan police officer died and dozens of others needed medical care while running the Chicago Marathon as record heat and smothering humidity forced race organizers to shut down the course midway through the event.

By 10 a.m., temperatures had already reached a race-record of 88 degrees. The previous marathon record of 84 degrees was set in 1979. Pinkowski said it was a tough decision to stop the race, but a prudent one.
