Hunter finds bones in wooded Rittman area (video)

Wayne County Coroner Amy Jolliff was overseeing the scene, Shows said. The area where the bones were found was about one mile west of South Main Street down a cinder road then "deep into the woods," Shows said.

BCI agents are working on grid-by-grid pattern to locate more bones. Shows said they are starting in a known area and working outward.

There are no reports of missing people in which to link the remains, Shows said.

Some people have speculated the bones could be from Susan Ryan, a Wooster woman who went missing June 5, 2010.

"It's a possibility, but from what we have, we can't tell. We have to collect the information," Shows said, adding later, "We don't have a dental record. We have to collect dental evidence."

The clothes the person was wearing have deteriorated. Flooding in the spring, the hot summer weather and possible animal activity have provided challenges.

"We need to get all of the evidence we can and then get back together and see what we have," Shows said. "It's one of those strange things. ... They left us one great, big mystery."
