Tualatin High School teacher arrested on sex charges

Sheriff's Office claims technology teacher abused underage student

Jonathan MaggianoDetectives with the Washington County Sheriff's Office have arrested a Tualatin High School teacher on sex abuse charges, and say that there may be additional victims who have yet to come forward.

Jonathan Maggiano, 32, was arrested on Friday after detectives say he engaged in inappropriate sexual conduct with at least one underage female student at the school.

Detectives began their investigation on Aug. 31 after a family member reported the sexual conduct, which sheriff's office spokesman Sgt. Bob Ray said occurred this summer in southeast Portland.

According to the Tigard-Tualatin School District, Maggiano started his career at the district in 2013 as a substitute teacher. He was hired last year as a technology teacher, teaching Introduction to Computers, Web Design and Computer Gaming. The school's website lists him as an adviser to the school's PC Gaming Club.

Maggiano was arrested at his home in southeast Portland on Friday morning and was briefly lodged in the Multnomah County Detention Center before posting $15,000 bail.

He faces charges of second-degree sex abuse, sexual misconduct, contributing to the sexual delinquency of a minor and luring a minor.

Maggiano is expected to be tried in Multnomah County, where the abuse allegedly took place. The Washington County Sheriff's Office conducted the investigation because the alleged victim is a Washington County resident, Ray said.

Portland police assisted in the arrest and transported Maggiano, Ray added.

The Sheriff's Office is also seeking any information on possible additional victims of unreported crimes.

Ray said investigators do not have "solid evidence" that Maggiano may have sexually abused any other minors but are concerned by the possibility.

"Because of his access to lots of underage people in the school, (that is) always a cause of concern," Ray said.

Anyone with information is asked to call the Washington County Sheriff’s Office detective division at 503-846-2500.

On Friday, Sept. 4, the Tigard-Tualatin School District issued a statement saying that it had placed Maggiano on administrative leave.

"We are shocked and very concerned about these charges and want to do all we can to support our students," the district wrote. " Additional counselors will be available at Tualatin High to support students when they return to school, next week."

Maggiano is the second area teacher to be arrested on child sex charges in the past few years. In 2013, Sherwood High School teacher Denise Keesee was arrested after abusing a male student. Another potential victim of Keesee is currently suing her in federal court.
