Derrick Alexander Barnum pleaded guilty April 11 to possession, distribution and production of child pornography.

A 25-year-old Houston resident has been ordered to federal prison after his multiple convictions involving child sexual abuse material (CSAM), announced U.S. Attorney Nicholas J. Ganjei.

U.S. District Judge Ewing Werlein Jr. has now sentenced Barnum to a total of 720 months in federal prison. He received 360 and 240 months for the production and distribution convictions, respectively, as well as another 120 months for the possession of CSAM.

They will all run consecutively for a total of 60 years in federal prison.  

At the hearing, the court heard additional information regarding the victim, who was only three at the time the exploitation began. The victim’s mother prepared and read from a victim impact statement which described how the minor victim needed counseling for the trauma Barnum caused and will live with his actions for the rest of their life. 

The court will determine and order restitution at a later date. Barnum will serve the rest of his life on supervised release following the completion of his prison term.

During that time, he will have to comply with numerous requirements designed to restrict his access to children and the internet. Barnum will also be ordered to register as a sex offender.
