A Florida man who pledged allegiance to Islamic State and distributed an online instructional video on making explosives was sentenced to 20 years in prison this week.
Roméo Xavier Langhorne pleaded guilty to trying to provide material support to ISIS last year after his arrest in 2019.
The 32-year-old, who was based in St. Augustine but also had ties to Roanoka, Va., initially pledged allegiance to Islamic State in 2014 and reaffirmed his support for the terrorist organization in 2018 and 2019 .
Langhorne began communicating in early 2019 with an undercover FBI agent posing as an ISIS operative and shared his plans to create a video about the making of a deadly explosive called triacetone triperoxide (TATP ).
TATP, sometimes called the “Mother of Satan,” is a common homemade explosive among terrorist groups due to its inexpensive precursor materials, according to the Director of National Intelligence.
Langhorne told the FBI agent that he wanted to create the bomb-making video to “arm ISIS adherents and others with knowledge of how to make TATP and use it at terrorism-related purposes in support of ISIS,” according to the U.S. Attorney’s Office for the Central District of Florida.
The FBI created a video from Langhorne’s instructions with an inert formula for TATP that wouldn’t actually explode, and Langhorne uploaded it to a website in November 2019. He was arrested days later.
“This dangerous individual’s willingness to go to great lengths to harm innocent Americans has always been very real, but through hard work and determination, the Jacksonville FBI Joint Terrorism Task Force has succeeded. to disrupt his plan early on and avert a threat to the safety of our community,” Sherri E. Onks, FBI Special Agent in Charge in Jacksonville, said in a statement Friday.
