An 82-year-old woman has died from injuries she sustained in the 1 June fire-bomb attack on a pro-Israel march in downtown Boulder, prompting prosecutors to upgrade charges against the alleged assailant to first-degree murder, the Boulder County District Attorney’s Office said Monday. The victim, Karen Diamond, was among 29 people identified as victims after Mohamed Sabry Soliman allegedly hurled Molotov cocktails and used a weed-sprayer filled with gasoline on demonstrators walking along Pearl Street Mall to draw attention to Israeli hostages held in Gaza. Thirteen people and a dog were physically injured; Diamond had been hospitalized with severe burns since the incident. Soliman, a 45-year-old Egyptian national living in the United States on expired visas, already faces 118 state counts that include attempted murder, assault and possession of incendiary devices. Last week a federal grand jury separately indicted him on 12 hate-crime counts, to which he entered a not-guilty plea in U.S. District Court in Denver. With Diamond’s death, prosecutors filed two state murder counts against Soliman, who remains in federal custody. A preliminary hearing in the state case is set for 15 July, while the federal case proceeds in parallel. If convicted on the combined charges, he could spend the rest of his life in prison.
