— The medical examiner is on the scene of a plane crash two-and-a-half miles west of Grand Ave. and 29th St., said Grady County Sheriff Art Kell.

He said a witness reporting hearing a "boom" when the plane hit the ground around 8 p.m. Friday evening. The witness called dispatch, Kell said, and members of the Pioneer Fire Department found the wreckage at about 10 p.m.

No information was available on the type of aircraft or how many victims may be involved.

"It's in pieces," Kell said. "You can't even tell it was a plane. There are pieces of corpse."

The sheriff was able to dispell speculation that the plane might have been a Festival of Light tour plane.

"We think it might have been a hunting trip. We found shotgun shells and hunting vests," he said.

Kell said the Oklahoma Highway Patrol is working the scene, but the sheriff's office will provide security through the night until the FAA arrives Saturday morning to continue the investigation.

"I talked to a trooper who has been around here 12 years and he said this is the first crash he knows of around here," Kell said. He also said more information would not be available until Monday.
