A human skull, jawbone and several small bones were found Monday morning on the Bear River several miles south of Corinne, but a Box Elder County Sheriff's Deputy said there was nothing to indicate foul play is involved.

"They have been there a long time," Box Elder County Sheriff's Deputy Lynn Yeates said of the bones, adding that the remains could be those of an Indian who died a hundred years ago or more.The bones, which were exposed by the low water level and a collapsing bank, were discovered by a fisherman, Yeates said.

The bones are those of an adult and are bleached, which indicates they have been exposed to the air for some time.

The bones will be sent to the state medical examiner's office to determine how long ago death occurred and the person's race and sex.

Yeates said he expects a report in about a month.
