A predatory sex offender who sexually abused a 16-year-old boy while living in Warrenton last fall was sentenced Monday in Clatsop County Circuit Court to more than two years in prison. Sidney Sean Mecham, 35, pleaded no contest to third-degree sodomy, third-degree sex abuse, unlawful delivery of marijuana, furnishing alcohol to a minor, interfering with making a report, menacing, harassment, endangering the welfare of a minor and failure to register as a sex offender.

Mecham is listed by Oregon State Police as a predatory sex offender following a 1999 conviction in Multnomah County. Despite having lived in Warrenton since July, Mecham reported his address as an apartment complex in southeast Portland.

The Clatsop County Sheriff’s Office and Warrenton Police arrested him in December at a residence on the 100 block of N.W. First Street in Warrenton.

Mecham reportedly met the victim by chance at a local park last summer and became a family friend. He provided the victim with marijuana, alcohol, and showed him sexually explicit material.

The abuse began in October. The victim was able to stop the abuse in late November and came forward to family members after further harassment from Mecham.

Family members then notified the Sheriff’s Office.

Between October and December, Deputy District Attorney Dawn Buzzard said, Mecham sent the boy 567 calls or texts, mostly during the night.

“The victim is having a difficult time struggling with this,” Buzzard said. “He had what he thought were feelings for this older man, but has come to realize it was not just illegal, but a wrong relationship that he was being taken advantage of.”

As part of his 28-month prison sentence, Mecham is ordered to have no contact with the victim and pay a $1,000 civil fine.
