A federal judge in Waco has explained why he added five years to the recommended 10 year sentence of a Temple man found guilty of possession of child pornography earlier this month.

As reported by Paul J. Gately with our news partner, KWTX, U.S. District Judge Alan D. Albright sentenced Jon Mark Johnson to 15 years in federal prison followed by five years of supervised release on November 14. Department of Justice guidelines recommend a maximum prison term of 10 years in cases in which the defendant is a first-time offender with no priors, but judges have the right to tack on more years if they believe the case warrants such action.

According to court records, Johnson displayed "an extraordinary lack of remorse to the victims" and behaved incorrectly during an early hearing.

Johnson pleaded guilty back in April. He'd been in federal custody since October of 2017.

According to records, Temple police began investigating Johnson in September of 2017 after his step-daughter reported that she found a camera in a bathtub in their home, which she believed Johnson used to photograph her without her consent. As police were obtaining a search warrant, Johnson reportedly destroyed computer files, hard drives, and CDs. The destroyed evidence was sent for forensic examination, along with other computer equipment and video materials found in Johnson's home.

Johnson reportedly admitted to police that he was addicted to pornography and in possession of sexually explicit images of children.
