Tennessee Man Pleads Guilty To Arson And Attempting To Provide Material Support To A Foreign Terrorist Organization

KNOXVILLE, Tenn. - On April 13, 2026, Regan Darby Prater, 28, currently of Tullahoma, TN, entered a guilty plea to one count of arson and one count of attempting to provide material support to a foreign terrorist organization. Prater pleaded guilty in the United States District Court for the Eastern District of Tennessee at Knoxville. Sentencing has been set before United States District Judge Thomas A. Varlan for September 9, 2026, at 10:00 a.m., in Knoxville.

Prater faces up to 20 years in federal prison, along with related fines, restitution, and a term of supervised release to be served after he is released from custody. As part of his agreement, Prater waived indictment by a Federal Grand Jury and agreed to plead guilty to the aforementioned charges.

Court documents establish that Prater used a so-called "sparkler bomb," i.e., a napalm-based incendiary device ignited by a common sparkler, to destroy facilities maintained by the Highlander Center, a school for grassroots leaders and social movements in New Market, Tennessee. As part of his guilty plea, Prater admitted that he drove from his home in Tullahoma to the Highlander Center, ignited the sparkler bomb, and destroyed a building, ultimately causing over $1.2 million in damage.

Before he detonated the bomb, Prater spray-painted the symbol of the Iron Guard, a 1930s-era paramilitary arm of the Romanian Nazi Party, in the Highlander Center parking lot. This same symbol was engraved on the rifle used in the terrorist attacks in Christchurch, New Zealand, just two weeks prior to the arson. Prater acknowledged that he committed the arson at the Highland Center due to his white-supremacist ideology and as a response to the Highlander Center's faith-based educational priorities and its association with the Civil Rights Movement.

Separately, Prater also admitted that, in 2019, he attempted to provide material support to Hizballah, also known as "Hezbollah," which the United States has recognized as a Foreign Terrorist Organization since 1997. Specifically, Prater obtained a document purporting to contain personally identifiable information of over 35,000 individuals purportedly affiliated with the government of Israel. He then provided that document to an individual he believed to be associated with Hizballah, stating, among other things: "Start the hunt."

Harmeet Dhillon, Assistant Attorney General of the Justice Department's Civil Rights Division; John Eisenberg, Assistant Attorney General of the Justice Department's National Security Division; U.S. Attorney Francis M. Hamilton III of the Eastern District of Tennessee; and Special Agent in Charge Terence G. Reilly of the Federal Bureau of Investigation (FBI) Nashville Field Office made the announcement.

This prosecution is the result of an investigation by the FBI, with assistance from the Tennessee Bureau of Investigation.

Assistant United States Attorneys Casey T. Arrowood and Kyle J. Wilson of the Eastern District of Tennessee are prosecuting the case with assistance from Trial Attorney Katherine McCallister of the Civil Rights Division and Trial Attorney Justin Sher of the National Security Division.
