CHICAGO (AP) -- An autopsy concludes it wasn't the heat that killed a Michigan police officer who was running in yesterday's Chicago Marathon. Instead, it was a heart condition.
Chad Schieber, who was 35, collapsed well into the race. And that led to speculation that his death was connected to the 88-degree temperatures that eventually caused organizers to stop the race.
Several others collapsed, and at least two are still in critical condition.
The medical examiner's office finds that the man who died had a condition called mitral valve prolapse, and that his death wasn't caused by the heat. It's described as a common disorder in which a valve doesn't close properly.
