BEAUMONT — A Beaumont man pleaded guilty Tuesday to federal violations in the Eastern District of Texas.

An issued statement from the office of U.S. Attorney Joseph D. Brown said Mark Avery Rudd, 27, pleaded guilty to possession of an unregistered destructive device before U.S. Magistrate Judge Keith Giblin.

Information presented in court revealed that on Feb. 8, law enforcement officers executed a search warrant at Rudd’s residence in the 4800 block of Belmont Street in Beaumont. There, investigators found a cooler in a hall closet containing two suspected destructive devices. One was a 2-liter bottle filled with an unknown viscous liquid with wires extending from the top of the bottle. One of the wires connected to an unknown device inside the liquid.

Because the device could not be safely identified, it was destroyed in accordance with safety procedures, the issued statement said. The second device was safely removed from the container and dismantled by federal agents. The second device consisted of a bottle of match heads, a pyrotechnic device, a can of butane and a can of capsaicin.

Inside Rudd’s bedroom investigators found a 21-page notebook containing numerous pages of handwritten notes, organized like a reference manual, with a table of contents and page numbers. The notebook contained detailed writing on explosives and explosives construction.

At the top of the first page was a handwritten note stating, “This is why you should not piss me off kabluey Chaos.”

Under federal statutes, Rudd faces up to 10 years in federal prison. Sentencing will be determined by the court based on the advisory sentencing guidelines and other statutory factors. A sentencing hearing will be scheduled after the completion of a presentence investigation by the U.S. Probation Office.

The FBI, Beaumont Police Department, Beaumont Fire Department and Beaumont Emergency Medical Services investigated the case.

Assistant U.S. Attorney Christopher T. Tortorice presented the case.
