PHOENIX — Michael Mattox, a 45-year-old Phoenix man, was sentenced to 20 years in the Arizona Department of Corrections for Sexual Exploitation of a Minor.
Mattox will also serve two consecutive terms of lifetime probation, and will be required to register as a sex offender, said a release from the Arizona Attorney General’s Office.
In 2017, Mattox posted images to an internet message board and posted messages in which he offered to trade child pornography.
Homeland Security Investigations (HSI), obtained a search warrant for the residence of Mattox in April 2018.
The Attorney General’s Office reported that “HSI located digital devices in Mattox’s bedroom.”
Investigators located images and video of child pornography that were downloaded from the internet, as well as images of child pornography that were created by Mattox.
Mattox confessed that he had been downloading child pornography for years.
The case was investigated by HSI and the Phoenix Police Department, prosecuted by Assistant Attorney General Joseph Waters and tried before Judge John Hannah in Maricopa County Superior Court.
