WYANDOTTE — A three-hour cadaver dog search of wooded and hilly terrain of Ottawa County failed to locate any human bones or remains on Tuesday, July 18, after a human skull was found in the area.

Ottawa County Sheriff Jeremy Floyd initiated a second phase of the investigation and brought in a team to hand-search the area after an unnamed person found a skull along a drive of a residence in the area on Friday, July 14.

The 12-person staff from the Oklahoma Emergency Response Team began searching using a grid pattern, spreading out over two acres of underbrush and trees.

The second search and a scaled back search on Wednesday, July 19, failed to yield any remains, Floyd said.

“We are strategizing for a new game plan,” Floyd told reporters on Wednesday.

On July 14, homeowners called authorities after finding a skull and what was presumed to be a leg bone in their driveway. The leg bone was later discovered to be an animal bone.

A presumed human hip bone was discovered in the same area on Sunday by authorities, Floyd said. The skull was intact and had pieces of tissue at the bottom where the jaw connects to the neck.

“There were no signs of trauma,” Floyd said.

The medical examiner’s preliminary investigation showed the skull was most likely male, he said.

A 20-to 25-year-old man, Eli Moss, was reported missing in the area June 30. He was last seen walking south of the Wyandotte area of Sycamore Bridge.

However, Floyd stated in a written release “rumor and speculation" the remains found belong Moss could not be confirmed nor repudiated by members of his department until the medical examiner concludes a formal identification process.

Floyd said officers continue to investigate Moss' disappearance as an ongoing, active case.
