Cows burned in cattle truck fire

EL RENO, Okla. — At least eight cows had to be put down after a truck hauling over 20 cattle caught fire Wednesday. 

Authorities said the brakes overheated and a tire blow out may have sparked the fire. 

The driver and most of the cattle made it out of the truck near I-40 and Banner Rd. 

Canadian County officials are investigating.
