Proud Boy Dominic Pezzola, breaking into the Capitol with other insurgents.

“The bearded, cigar-smoking Proud Boys member who led the Capitol’s invasion by a pro-Trump mob had manuals for making bombs, guns, and poisons on a thumb drive, federal prosecutors allege.

Dominic Pezzola, 43, was among the first rioters to charge the police lines during the Capitol’s insurrection following a pro-Trump rally on January 6, court documents say. 

The document, which argues for his pretrial detention, alleges he used a police riot shield to smash a Capitol window to let people in, making him “among the first — if not the first” to get inside the building.

His actions showed “planning, determination, and coordination,” prosecutors say.

The Proud Boys are a right-wing group of nationalists whose rallies are associated with violence and was a significant presence at the Capitol insurrection. Leader Enrique Tarrio was arrested the day before the riots on property destruction charges stemming from an earlier protest.

A police search of Pezzola’s home revealed a thumb drive containing hundreds of detailed pdfs, with titles including:

• Several titles in a series called “Advanced Improvised Explosives.”
• A book subtitled “The Ultimate DIY Machine Pistol.”
• “Ragnar’s Big Book of Homemade Weapons.”
• “The Advanced Anarchist’s Arsenal: Recipes for Improvised Incendiaries and Explosives….>”
