At least one person was killed Sunday when a string of tornadoes tore through four states, ripping roofs off homes, downing power lines and tossing trees like matchsticks.

The death happened at a trailer park in Pottawatomie County, Oklahoma, said Sheriff Mike Booth. He had no details, other than the deceased was an adult male.

Booth said that two other people are missing from that same park, where a number of people were also injured, two seriously.

Rescue crews were picking through the mangled metal remains of mobile homes as darkness fell Sunday.

As many as 26 tornadoes were reported in Oklahoma, Kansas, Illinois and Iowa, according to the National Weather Service, with Oklahoma and Kansas being the hardest hit. Some of those reports might have been of the same tornado.
