A Wichita Falls man who plotted to blow up a data center in Virginia pleaded guilty Wednesday to malicious attempt to destroy a building with an explosive, announced Acting U.S. Attorney for the Northern District of Texas Prerak Shah.

Seth Aaron Pendley, 28, was arrested in April after attempting to obtain an explosive device from an undercover FBI employee in Fort Worth. He entered his guilty plea today before U.S. Magistrate Judge Hal R. Ray, Jr.

“Due in large part to the meticulous work of the FBI’s undercover agents, the Justice Department was able to expose Mr. Pendley’s twisted plot and apprehend the defendant before he was able to inflict any real harm,” said Acting U.S. Attorney Prerak Shah. “We may never know how many tech workers’ lives were saved through this operation – and we’re grateful we never had to find out. Bringing to justice domestic extremists remains one of the Department’s top priorities.”
