ARDMORE, Okla. -- Police in Ardmore say they are hoping for a break in the case of human remains found last week. A group of children found several bones including a human skull in a creek bed in the 300 block of F Street Southeast and 3rd Avenue last Thursday.

Investigators hope to match the bones to a man named Jimmy Frank McCullough, who disappeared from the Gold Mountain Casino more than two years ago.

But that is the only lead they have right now, and the investigation is far from over.

"We searched that area, and the Medical Examiner’s Office was called, and the human remains were taken to the Oklahoma City to the Medical Examiner’s Office," Captain Kevin Woods of the Ardmore Police Department said.

The remains have since been sent to a lab in Austin, Texas, for DNA testing.
