Boulder Firebomber Charged With Murder Following Death of Victim

A victim of the antisemitic Boulder, Colorado firebombing died on Monday, prompting local law enforcement to charge suspect Mohamed Soliman with murder in the first degree.

“Severe injuries” caused the death of Karen Diamond, 82, the Boulder County District Attorney’s Office (BCDA) said on Monday in a statement. She was one of 13 people injured when Soliman hurled Molotov cocktails into a crowd of Jewish people who were participating in a demonstration to raise awareness of the hostages who remain imprisoned by Hamas in Gaza. Her death adds five new charges to the over 200 federal and state criminal charges which could lock Soliman away for over 600 years.

“These additional charges, including the counts of First Degree Murder, are being filed after consultation with the US Attorney’s Office, Federal Bureau of Investigation, and the Boulder Police Department,” said the DA’s office, adding that it “continues to work closely with federal, state, and local partners in the strong response to this attack. We stand united against acts of antisemitism and hate.”

“This horrific attack has now claimed the life of an innocent person who was beloved by her family and friends,” said Michal Dougherty, district attorney of Boulder County. “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. 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.”

Prosecutors said in May that Soliman yelled “Free Palestine” during the attack, and, according to court documents, told investigators that he wanted to “kill all Zionist people.”

That incident came less than two weeks after a gunman murdered two Israeli embassy staffers in Washington, DC, while they were leaving an event at the Capital Jewish Museum hosted by the American Jewish Committee. The suspect charged for the double murder, 31-year-old Elias Rodriguez from Chicago, also yelled “Free Palestine” while being arrested by police after the shooting, according to video of the incident. The FBI affidavit supporting the criminal charges against Rodriguez stated that he told law enforcement he “did it for Gaza.”

In Garret Park, Maryland, a middle-aged man, Clift A. Seferlis, was recently arrested by federal authorities for sending a series of threatening messages to Jewish organizations in Philadelphia. Seferlis referenced the war in Gaza in his communications.

“The Victim Jewish Institution 1 received numerous additional messages since April 1, 2024, which contained a threat to physically destroy the institution,” the US Attorney’s Office for the Eastern District of Pennsylvania said in a statement. “Prior to the receipt of the May 7, 2025, mailing, Victim Jewish Institution 1 and its employees had received very similar-looking letters, believed to have been sent by Seferlis, which referenced Victim Jewish Institution 1’s ‘many big open windows,’ ‘Kristallnacht,’ ‘anger and rage,’ and a future need to ‘rebuild’ the institution following its destruction.”

Another antisemitic incident motivated by anti-Zionism occurred in San Francisco, where Juan Diaz-Rivas, Alejandro Flores-Lamas, and others law enforcement is working to identify, allegedly beat up a Jewish victim in the middle of the night. Diaz-Rivas and Flores-Lamas, along with their associates, approached the victim while shouting “F—ck the Jews, Free Palestine,” according to the office of the San Francis district attorney.

“[O]ne of them punched the victim, who fell to the ground, hit his head and lost consciousness,” the district attorney’s office said in a statement. “Allegedly, Mr. Diaz-Rivas and others in the group continued to punch and kick the victim while he was down. A worker at a nearby business heard the altercation and antisemitic language and attempted to intervene. While trying to help the victim, he was kicked and punched.”

According to data released by the Anti-Defamation League’s (ADL) latest Audit of Antisemitic Incidents in April, antisemitism in the US is surging to break “all previous annual records.”

In 2024 alone, the ADL recorded 9,354 antisemitic incidents — an average of 25.6 a day — across the US, an eruption of hatred not recorded in the nearly thirty years since the organization began tracking such data in 1979. Incidents of harassment, vandalism, and assault all increased by double digits, and for the first time ever a majority of outrages — 58 percent — were related to the existence of Israel as the world’s only Jewish state.

The Algemeiner parsed the ADL data, finding dramatic rises in incidents on college campuses, which saw the largest growth in 2024. The 1,694 incidents tallied by the ADL amounted to an 84 percent increase over the previous year. Additionally, antisemites were emboldened to commit more offenses in public in 2024 than they did in 2023, perpetrating 19 percent more attacks on Jewish people, pro-Israel demonstrators, and businesses perceived as being Jewish-owned or affiliated with Jews.

“In 2024, hatred toward Israel was a driving force behind antisemitism across the US, with more than half of all antisemitic incidents referencing Israel or Zionism,” Oren Segal, ADL senior vice president for counter-extremism and intelligence, said when the report was released. “These incidents, along with all those documented in the audit, serve as a clear reminder that silence is not an option. Good people must stand up, push back, and confront antisemitism wherever it appears. And that starts with understanding what fuels it and learning to recognize it in all its forms.”
