Karen Diamond, an 82-year-old Holocaust survivor from Boulder, passed away on June 25 due to injuries sustained in a June 1 firebomb attack during a peaceful pro-Israel solidarity march on Pearl Street Mall. She had been in critical condition after being severely burned by a Molotov cocktail tossed amidst the crowd. Diamond’s death marks the first fatality among the 29 people affected by the incident.

Diamond, born in Hungary in 1942, fled Europe as a child during the Holocaust and later built a life in Colorado as a devoted community volunteer. She was deeply involved with Congregation Bonai Shalom, helping refurbish the synagogue after the 2013 floods, and was a longtime participant in the Boulder Jewish Community Center and the University Women’s Club. “There are no words to express the pain of this horrific loss of our beloved member and friend,” said Rabbi Marc Soloway.

Following Diamond’s passing, Boulder County District Attorney Michael Dougherty issued a statement: “This horrific attack has now claimed the life of an innocent person who was beloved by her family and friends,” adding, “Our office will fight for justice for the victims, their loved ones, and the community.”

The Attacker: Disguised, Radicalized, and Unrepentant

Police arrested Mohamed Sabry Soliman, a 45-year-old Egyptian national who had been living illegally in Colorado Springs. He entered the U.S. on a tourist visa in August 2022, applied for asylum, and was living in the country after his visa expired. Prosecutors say he disguised himself in a high-visibility vest and used a backpack flamethrower and Molotov cocktails, shouting “Free Palestine!” during the attack.

Charging documents state Soliman admitted planning the attack for over a year, targeted “Zionists,” and showed no remorse. He is facing 118 state charges—including attempted murder, assault, use of incendiary devices, and animal cruelty (a dog was injured)—plus 12 federal hate crime counts. He has pleaded not guilty to all charges.

Legal Implications: From Attempted Murder to Homicide

Diamond’s death has triggered prosecutors to upgrade charges against Soliman: two counts of first-degree murder under Colorado law—one based on intent after deliberation, another on extreme indifference to human life.

Colorado abolished the death penalty in 2020, so a murder conviction guarantees life in prison without parole. Boulder County DA Dougherty emphasized that Diamond’s death marks a turning point: “Her death changes everything … What began as a horrifying act of violence now has the weight of a homicide—tied directly to antisemitic ideology,” as legal analysts note.

Soliman is scheduled to appear in state court on July 15 for the formal arraignment on murder and other charges. Federal prosecutors are expected to continue coordinating closely to ensure full accountability under hate crime statutes and homicide law.


Her passing, at the hands of hatred, has ignited deep sorrow and outrage across Boulder’s Jewish community, interfaith groups, and civic leaders. Governor Jared Polis called her murder “devastating and unacceptable,” and a renewed focus on protecting marginalized communities has emerged.

The escalation from a violent attack to a formal murder case underscores the legal and moral weight her death carries. As her memory galvanizes efforts to stand against hate, prosecutors aim to ensure justice is delivered—and that her legacy of resilience and kindness is honored in full.
