A hiker spotted a skull and a tennis shoe Sunday afternoon along a creekbed in a remote area of Shiloh Ranch Park in Windsor, said sheriff's Lt. Steve Brown.

The man, who was hiking with his two young children, called 911 at about 2:20 p.m. to report the finding.

Deputies confirmed the remains were human and secured the site until detectives can begin an investigation Monday morning.

"There's a full skeletal remains there," Brown said.

Other than the shoe, clothing wasn't evident, he said.

Shiloh Ranch Park, a Sonoma County regional park, is off of Shiloh Road and Faught Road, east of Windsor.
