HILLSBORO, Ore.- On April 19, 2022, A Washington County jury found David Gordon Propp, age 51, guilty of three counts of using a child in 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. Senior Deputy District Attorney Andy Pulver prosecuted the case against the defendant. 

Mr. Propp is a convicted sex offender. He used a dating app to initiate contact with the victim, who was under the age of 18 at the time. On August 14, 2019, Hillsboro police spotted an SUV parked in a field and approached the vehicle. They observed the victim and the defendant attempting to put their clothes back on. The victim later told police that the defendant engaged him in sexual activity. 

The victim spoke with experts at CARES Northwest where he disclosed an additional encounter with Mr. Propp. Investigators with the Northwest Regional Computer Forensics Laboratory also discovered thousands of messages exchanged via the app between the victim and defendant. They uncovered multiple conversations in which the defendant solicited and received compromising images of the victim. 

The Washington County District Attorney’s Office wishes to commend the victim for his courage throughout this investigation and trial. Additionally, this office acknowledges the work of the Hillsboro Police Department, CARES Northwest, and the Northwest Regional Computer Forensics Laboratory. 

A sentencing hearing is scheduled for June 16, 2022. The defendant will remain in custody until that time. 

This office is also working with partners across Washington County to honor Child Abuse Prevention Month. For more information on support for survivors, please visit the Washington County District Attorney’s website.
