HOUSTON (CBSDFW.COM/AP) – A Royse City man must serve 10 years in federal prison after a child sex investigation led to more than two dozen homemade bombs.
Mark Duesterberg was sentenced Thursday in Houston. The 34-year-old Duesterberg, who formerly lived in Spring, earlier pleaded guilty to enticing a minor and to unlawful making of weapons.
Prosecutors say Duesterberg last year communicated online with some he thought was a girl and tried to entice her into a sexual relationship. Duesterberg arranged to meet the person, who turned out to be an undercover agent, and was arrested at the scene.
According to a news release from the U.S. Attorney’s Office, on May 28, 2015, Duesterberg communicated with an undercover agent, an individual whom he believed was an underage girl. In the course of the email and text messages, he persuaded, induced and attempted to entice the girl to have sex with him. He made arrangements to meet the girl to engage in sexual activity and when he got there, authorities arrested him. At that time, agents discovered seven pipe bombs within his vehicle.
The following morning, law enforcement traveled to Duesterberg’s Spring residence and conducted a search of the location.
In the garage, they located 25 explosive bombs which he had not received prior permission to make.
An expert later determined these were destructive devices and that the explosives within would propel metal, PVC and CPVC fragments at high velocities and in all directions. These explosives could cause property damage and would be capable of causing injury or death to persons near the explosion.
