Boulder Molotov Attack Claims First Victim
The Boulder Molotov attack that shocked the Colorado community has turned fatal. Prosecutors announced Tuesday that Karen Diamond, 82, succumbed to severe injuries sustained during the June 1 assault outside the Boulder courthouse.
Diamond’s death led the Boulder County District Attorney’s Office to upgrade the main charge from attempted murder to first-degree murder against the suspect, Mohamed Soliman.
Community Mourns Loss of Cherished Member
“There are simply no words to properly express the pain of this tragic loss,” the Boulder Jewish Community Center said in a statement. “Karen was a cherished member of our community, someone whose warmth and generosity left a lasting impact on all who knew her. She will be deeply missed.”
District Attorney Michael Dougherty also expressed condolences: “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.”

Attack Details: Molotov Cocktails and Hate-Fueled Motivation
According to prosecutors, the Boulder Molotov attack occurred when Soliman allegedly threw Molotov cocktails at marchers advocating for the release of Israeli hostages. The incident happened on June 1 outside the Boulder courthouse on Pearl Street, where more than a dozen people were injured.
During the attack, Soliman reportedly shouted “Free Palestine” and later told police he had been planning the assault for a year, according to court documents.

Suspect’s Alleged Statements to Police
Court documents reveal that Soliman allegedly stated he wanted to kill all Zionist people, clarifying that his intent targeted Zionist supporters specifically, not the Jewish community as a whole. However, authorities note that many victims were part of Boulder’s Jewish community.
Charges Against Mohamed Soliman Expanded
Following the ongoing investigation, prosecutors said they discovered 14 additional victims of the attack. As a result, the state indictment now includes 66 new charges, bringing the total to an extensive list of counts against Soliman, including:
- First-degree murder
- Attempted first-degree murder
- First-degree assault
Soliman remains in federal custody and pleaded not guilty to federal hate crime charges last week.
Next Steps in the Case
Soliman’s preliminary hearing on the state charges is set for July 15. The Boulder County District Attorney’s Office emphasized their commitment to pursuing justice and supporting the victims’ families.
Community Reacts to Rising Violence
The fatal outcome of the Boulder Molotov attack has intensified concerns over hate-motivated violence targeting communities across the country. Local leaders and organizations are calling for increased vigilance and solidarity in the wake of this tragedy.
