The Boulder, Colorado domestic terrorism suspect spent a year preparing to hurl Molotov cocktails into a peaceful pro-Israel march, court documents revealed.

Mohamed Sabry Soliman, an Egyptian national whose visa, which was granted during the Biden administration, expired in March 2025, told federal authorities that the violence was a long time in the making.

In an interview with authorities, according to the federal complaint, the suspect said he was waiting for his daughter’s graduation before carrying out the attack.

A video later posted on X appeared to show the suspect shirtless and pacing, holding one of the makeshift weapons and shouting, “How many children killed?” followed by, “End Zionist.”

Law enforcement also searched Soliman’s home, where he said he had left a journal and an iPhone containing messages to his family. His wife later turned over the phone to authorities. 

A storage unit behind the residence, linked to Soliman by a neighbor, was also investigated.

Soliman is charged with violating 18 U.S.C. §§ 249(a)(1) and (a)(2), federal hate crime statutes involving acts motivated by race, religion, or national origin.
