Boulder Firebombing Attacker Sentenced to Life in Prison After Guilty Pleas

Separate federal hate‑crime charges could still bring a death‑penalty decision.

Overview

  • Mohamed Sabry Soliman, 46, was sentenced to life without parole in Boulder County District Court on Thursday after pleading guilty to 101 state charges, including first-degree murder.
  • Prosecutors say he threw two Molotov cocktails and sprayed gasoline at a June 1, 2025 rally on Pearl Street Mall, killing 82-year-old Karen Diamond and injuring more than a dozen people.
  • Court records and investigators say he planned the attack for about a year, yelled “Free Palestine,” carried extra firebombs, and told authorities he wanted to “kill all Zionist people.”
  • A separate 12-count federal hate‑crime case remains active as prosecutors consider seeking the death penalty, and his lawyers say he has offered to plead there in exchange for a life sentence.
  • His ex‑wife, Hayam El Gamal, and five children were detained by immigration officials, released by court order in April, and are now the focus of motions to block deportation because they are sought as potential witnesses in the federal case.
