Former Beaverton mayor Dennis “Denny” Doyle has been charged with possessing child pornography, federal prosecutors announced Friday.

A criminal information document filed in court alleges Doyle possessed digital material containing child pornography, including images depicting minors under 12, between November 2014 and continuing through December 2015.

The charges stem from an old computer thumb or flash drive that was turned over to authorities containing the alleged pornography and other personal material belonging to Doyle, according to a source familiar with the investigation.

The FBI’s Child Exploitation Task Force in Portland investigated the case.

Doyle was expected to make his first appearance before a federal magistrate judge Friday afternoon.

Doyle did not immediately respond to messages seeking comment. Assistant Federal Public Defender Elizabeth Daily confirmed she’s representing Doyle but declined comment at this time.

Doyle, 73, served as a Beaverton councilman for more than a decade before he was elected mayor in 2008. He served three terms in the city’s top elected position, relinquishing the job in 2020 after he was beaten in a runoff election.

In 1993, Doyle helped found the Westside Metros Soccer Club, a nonprofit youth soccer club that hired professional coaches to lead about 30 boys and girl soccer teams. When he took office, he was a paid employee of the club. The club is now the Westside Timbers Soccer Club.

In 2008, Doyle was named Citizen of the Year by the Boy Scouts of America, then recognized for his longtime community service and work with youth sports. In addition to founding the Westside Metros Soccer Club, he served on the Westside Recreational Soccer Club Board and was a board member of the Beaverton Baseball and Softball Association. He had sat on the Tualatin Hills Park & Recreation District’s board, and on school committees for Beaverton High School and Sexton Mountain Elementary School.
