David Lee Cannon, Child Pornography, Oregon 2025

PORTLAND, Ore.—David Lee Cannon, a 36-year-old Portland man and registered sex offender, has been sentenced to federal prison for possession of over 200 images of child sexual abuse material (CSAM).

According to court documents, law enforcement officials discovered Cannon was collecting CSAM images during an investigation into his uncle's activities in February 2024. Cannon sought images from his uncle over Telegram, an encrypted messaging application. Additional evidence of CSAM material was found after a search of Cannon's devices.

Cannon is a registered sex offender after a 2009 conviction for possessing CSAM material. This new conviction has resulted in a 10-year federal prison sentence for Cannon.

“The pursuit of individuals who exploit and abuse children is our highest priority,” said Scott E. Bradford, U.S. Attorney for the District of Oregon. “With today’s sentence, Mr. Cannon will spend the next 10 years behind bars, unable to victimize any other children.”

Cannon was arrested in Milwaukie, Oregon, after HSI agents tracked his cellphone. He was charged by information on April 28, 2025, and pleaded guilty to Possession of Child Pornography on June 26, 2025.

This case was investigated by HSI with assistance from Hillsborough County Sheriff's Office. It was prosecuted by Assistant U.S. Attorneys Mira Chernick and Paul Maloney.

David Lee Cannon, 36, was sentenced to 120 months in federal prison and a life term of supervised release. The sentence will see Cannon behind bars for the next 10 years, unable to victimize any more children.

Federal law defines child pornography as any visual depiction of sexually explicit conduct involving a minor. It is crucial to remember that child sexual abuse material depicts actual crimes being committed against children, and sharing these images across the internet re-victimizes and re-traumatizes the child victims each time their abuse is viewed.
