Autopsy: Heart Problem in Chicago Runner By CARYN ROUSSEAU, Associated Press Writer 2 hours ago CHICAGO - An autopsy showed a heart condition, not record-setting heat, killed a Michigan police officer who died during an unusually hot and humid Chicago Marathon. Chad Schieber, who collapsed while running on the city's South Side, had a mitral valve prolapse and did not die from the heat, the medical examiner's office said Monday. The 35-year-old Schieber, from Midland, Mich., was pronounced dead shortly before 1 p.m. Sunday at a hospital.
