An 82-year-old woman has died from injuries she sustained during a firebombing attack in Boulder last month, when a man targeted peaceful marchers who were calling for the release of hostages held by Hamas in Gaza. 

Karen Diamond died of severe injuries, according to a Monday statement from the Boulder County District Attorney’s Office. The office has identified 29 victims of the attack on the Pearl Street Mall, 13 of whom were physically injured.

“This horrific attack has now claimed the life of an innocent person who was beloved by her family and friends,” Michael Dougherty, the district attorney, said in the statement. “Our hearts are with the Diamond family during this incredibly difficult time. Our office will fight for justice for the victims, their loved ones, and the community.”

Dougherty added, “Part of what makes Colorado special is that people come together in response to a tragedy; I know that the community will continue to unite in supporting the Diamond family and all the victims of this attack.” 

Diamond was a participant in the Boulder branch of Run For Their Lives, an organization that has led weekly walks in the city’s downtown area for nearly two years in support of the release of hostages taken by Hamas during the Oct. 7, 2023, attack on Israel. There are still 50 hostages in Hamas captivity, according to The Associated Press.

The suspect in the attack allegedly told police that he targeted the demonstration because he wanted to “kill all Zionist people.”

Mohamed Sabry Soliman, a 45-year-old Egyptian citizen, has been charged as the suspect in the attack. He now faces first-degree murder charges, as well as federal hate crime charges and more than 100 state-level criminal charges. A preliminary hearing in the state case is set for July 15.
