Four die of injuries from wrecks on Oklahoma roads

Wolf was pronounced dead at the scene. Watts and a passenger in his tractor-trailer were not injured. Everyone was wearing a seat belt, troopers said.

Fay Baker, 90, of Crawford, Ark.

Baker died Wednesday from injuries she suffered in a wreck Sunday on I-40 in Caddo County.

She was a passenger in a pickup driven by Nancy Baker, 73, of Crawford, Ark. About 2:50 p.m., their pickup and a second one driven by Ronald Squires, 41, of Weatherford, were both heading west on I-40 when Squires' pickup hit Bakers' pickup from behind, troopers said.

Bakers' pickup hit an exit sign, then ran through a fence, coming to rest in a wheat field. Squires told troopers he fell asleep at the wheel.

Fay Baker was taken to OU Medical Center, where she died Wednesday. All involved were wearing seat belts.
