“Skyler Philippi, 24, of Columbia, Tennessee, was arrested by federal agents and charged with attempting to use a weapon of mass destruction and attempting to destroy an energy facility. Beginning in June 2024, Philippi told a confidential human source (CHS) about his desire to commit a mass shooting at a YMCA facility located in or around Columbia, Tennessee. In July 2024, Philippi told another CHS about the impact of attacking large interstate substations and said that attacking several substations would ‘shock the system,’ causing other substations to malfunction.”
“Philippi researched previous attacks on electric substations and concluded that attacking with firearms would not be sufficient. Philippi, therefore, planned to use a drone with explosives attached to it and to fly the drone into the substation. In September 2024, Philippi drove with undercover employees (UCEs) of the FBI to an electric substation previously researched and targeted by Philippi, and Philippi conducted reconnaissance of the substation. While driving, Philippi ordered a plastic explosive composition known as C-4 and other explosives from the UCEs. Philippi later purchased black powder to be used in pipe bombs, which Philippi intended to use during the attack on the substation. Philippi texted the CHS: ‘if you want to do the most damage as an accelerationist, attack high economic, high tax, political zones in every major metropolis.’ Referring to the substation, Philippi stated, ‘Holy shit. This will go up like a fuckin fourth of July firework.’ Philippi talked about operational security, including the need for disguises, the use of leather gloves (because latex and nitrile gloves can transfer fingerprints), wearing shoes that are too big, the need to burn their clothes after the attack, and not bringing smartphones on the night of the attack.”
