Searing heat that left the Midwest gasping Sunday contributed to at least four deaths over the weekend and sent hundreds of fans at air shows, auto races and baseball games seeking medical help.
Temperatures reached 100 degrees in Carbondale, Ill., 99 degrees in Lamoni, Iowa, and 98 degrees in Kansas City, Mo., on Sunday, prompting heat advisories and warnings in those states.
On Saturday, two people suffered heart attacks at a NASCAR race at Gateway International Raceway in Madison, Ill., and died later at hospitals.
At least nine others who went to the track in southeastern Illinois were taken to hospitals and more than 150 people were treated, most for heat-related problems.
A Moline, Ill., man walking in a seven-mile race in Davenport, Iowa, died Saturday. Relatives of 62-year-old Charles B. Crowe blamed the heat, but authorities had not determined the cause.
Heat also was suspected in the death of a 60-year-old St. Louis woman who suffered cardiac arrest after arriving home from a picnic Saturday. An autopsy was pending.
About 130 fans at the Kansas City Airshow on Saturday had to be treated for the heat with fluids and ice packs. One young girl passed out and hit her head and was taken away by ambulance. Her status was not available.
And at a Cardinals game at Busch Stadium in St. Louis, where temperatures on the field hit 120 degrees, 48 people were treated for heat problems.
