Convicted sex offender found guilty in sexual abuse case

By KATU Staff

HILLSBORO, Ore. — A convicted sex offender was found guilty on several sex crimes last week, accused of sexually abusing an underage male he met through a dating app.

David Gordon Propp, 51, was found guilty last Tuesday (April 19) of three counts of using a child in a display of sexually explicit conduct, four counts of luring a minor, four counts of second-degree sexual abuse, two counts of third-degree sexual abuse, and tampering with a witness.

The investigation started in August of 2019 when Hillsboro Police officers approached a vehicle that had been parked in a field. They saw two people inside the SUV trying to put their clothes back on.

“The victim later told police that the defendant engaged him in sexual activity,” the Washington County District Attorney’s Office said. “The victim spoke with experts at CARES Northwest where he disclosed an additional encounter with Mr. Propp.”

Investigators learned that Propp used a dating app to first contact the sexual abuse survivor, who was under 18 years old at the time. Police also found thousands of messages between them on the app, including some where Propp solicited and received “compromising images.”

Propp’s sentencing hearing is scheduled for June 16, 2022
