Surveillance footage reviewed by investigators and cited in court showed a suspect identified as Calvert wearing a dark jacket with a blue face mask and goggles walking around the area of the explosion from 2:50 a.m. to 3:43 a.m. He was later seen affixing several stickers on the door of the Capitol building with typical leftist phrases such as “Support your local Antifa,” “Anti-fascism is community self-defense,” “Eat the rich,” “Never work,” and “Friends don’t let friends become cops.” The explosion occurred at 3:42 a.m.
The Tribune described the explosive device as being constructed from a "coffee container-like vessel which contained insulation material soaked in a flammable substance, a mortar, firecrackers." The device also contained nails to generate lethal shrapnel.
Security footage showed Calvert fleeing the scene in a vehicle that was registered to him. Agents with the FBI were further able to link Calvert to the incident by reviewing his social media, in which he posted images of him wearing similar goggles and showing the stickers he left on the Capitol in detail.
Marshall said in a statement issued two days later, “In the early hours of Saturday, February 24, an explosive device was detonated outside of the Alabama Attorney General’s Office building in Montgomery. Thankfully, no staff or personnel were injured by the explosion.”
