An estimated 300 heavily damaged vehicles remain scattered in the Oklahoma City suburb. City Manager Steve Eddy says if the vehicles are not claimed by 8 p.m. Wednesday the city will have them towed away and the owners will have to pay the expenses.

About 30 autos are in the parking lot of Moore Medical Center and a hospital spokeswoman told The Norman Transcript that none belong to hospital employees. She says some may have been thrown into the lot by the tornado while others may have been dragged there if they were blocking a street.
