Cowlitz County authorities say that a skull found in the Mount Brynion woods last week has been identified as that of a Kelso man who vanished in 2010.

The Longview Daily News reports (http://bit.ly/16oxM4b) that the county coroner identified the skull on Friday as 29-year-old Sam Stefonek. The coroner’s office and the Washington State Patrol’s Missing and Unidentified Person Unit used dental records to identify the skull.

Coroner Tim Davidson says the skull showed no signs of trauma and because only the skull was found, his cause of death remains unknown.

Stefonek disappeared Aug. 8, 2010. Authorities say he argued with his girlfriend and then fled into the woods behind his parents’ home. His cellphone was later found nearby.
