A Tucson man, Duane “Sparky” Lee Johnsen, has been sentenced to 168 months in prison for possessing child pornography.
Johnsen, age 55, was found guilty of Receipt, Knowing Access, and Possession of Child Pornography after a three-day federal jury trial in September 2023.
When Johnsen is released from prison, he will be on lifetime supervised release and will be required to register as a sex offender.
According to the Department of Justice, Johnsen was found in possession of child sex abuse images through an investigation by Homeland Security Investigations (HSI) in Tucson, which located individuals using file-sharing programs to obtain these images.
When HSI executed a search warrant at Johnsen’s home in December 2019, agents recovered numerous computers and digital storage devices which contained large amounts of data. Examination of the digital items confirmed that Johnsen had been searching for, downloading, categorizing, and saving very large numbers of child sex abuse images, including prepubescent victims, on several of his devices.
Johnsen was also in possession of other material related to child sex abuse, including a manual on how to groom children and animated comics depicting sexual abuse of children.
