One Runner Dead, 250 Hospitalized, After Extreme Heat Halts Chicago Marathon

Organizers shut down the course four hours after the start of Sunday's Chicago Marathon because of 88-degree heat and sweltering humidity that left one runner dead and sent 250 people to area hospitals with heat-related ailments.

Chad Schieber of Midland, Michigan, 35, collapsed while running on the South Side and was pronounced dead shortly before 1 p.m. at a Veteran's Affairs hospital, the Cook County medical examiner's office. An autopsy was scheduled for Monday.
