Storms Kill At Least 15

Severe storms and tornadoes tore through Texas, Arkansas, and Oklahoma Sunday, killing at least 15 people, injuring scores more, and cutting power to hundreds of thousands across the region. 

 A devastating twister struck a rural area near a trailer park in Cooke County, Texas, killing at least seven, including two children. The storm also destroyed a truck stop where people sought shelter in a restroom. 

At least five others were killed in Arkansas and two in Oklahoma. Farther east, the severe weather caused a race delay and the evacuation of 125,000 attendees at the Indianapolis 500 on Sunday.
