Tucson man, repeat offender sentenced to 10 years for child pornography offense following ICE HSI investigation

TUCSON, Ariz. – A southern Arizona man was sentenced Tuesday to 10 years in prison for possession of child pornography following a probe by U.S. Immigration and Customs Enforcement’s (ICE) Homeland Security Investigations (HSI) Tucson office.

Zachary Zane Stephenson, 45, of Tucson, previously pleaded guilty to one count of possession of child pornography.

“Because of the outstanding efforts of our HSI agents, a repeat offender guilty of exploiting vulnerable children will serve a lengthy federal prison sentence,” said Scott Brown, special agent in charge of HSI Phoenix. “HSI does not tolerate this type of behavior and will continue to prioritize these types of investigations to protect children and remove these offenders from our communities.”

On Oct. 28, 2020, Stephenson, who was on supervision at the time in connection with a similar prior conviction, was charged after he was found to be using his cellphone to access graphic child sexual abuse material. Upon release from prison, Stephenson will be placed on lifetime supervised release with stringent conditions of supervision. He will be required to register as a sex offender and to complete a sex offender treatment program.

The case was brought as part of Project Safe Childhood, a nationwide initiative by the Department of Justice to combat the epidemic of child sexual exploitation and abuse. Led by U.S. Attorneys’ Offices and the Criminal Division’s Child Exploitation and Obscenity Section (CEOS), Project Safe Childhood marshals federal, state, and local resources to better locate, apprehend, and prosecute individuals who exploit children via the internet, as well as to identify and rescue victims.
