One of the victims in the June 1 attack of Israeli hostage supporters on Boulder’s Pearl Street Mall has died, and the suspect now faces first-degree murder charges, according to the 20th Judicial District Attorney’s Office.
Mohamed Sabry Soliman is charged both at the state and federal level with attacking with Molotov cocktails a group of people from Run for Their Lives while they were advocating for the release of Israeli hostages in Gaza on June 1.
The district attorney’s office also updated the number of victims in the attack to 29 people, with 13 of them suffering “physical injury during the attack,” according to a Monday morning press release.
The district attorney’s office on Monday identified 82-year-old Karen Diamond as the victim who died “tragically as a result of the severe injuries that she suffered in the attack.” The Boulder County Coroner’s Office said Diamond died on Wednesday, June 25.
“This horrific attack has now claimed the life of an innocent person who was beloved by her family and friends. 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.” - District Attorney Michael Dougherty
The DA’s office amended two counts of attempted murder to first-degree murder for Diamond’s death. Count 4 charges first-degree murder under an extreme indifference theory and Count 5 charges first-degree murder with intent and after deliberation.
In addition to that, the DA’s office added 66 counts related to the 14 additional victims who have now been identified.
Here is the list of new total charges in the criminal complaint:
2 counts of first-degree murder,
52 counts of attempted first-degree murder,
8 counts of first-degree assault,
18 counts of attempted first-degree assault,
2 counts of third-degree assault,
2 counts of using an incendiary device,
16 counts of attempted use of an incendiary device and
1 count of animal cruelty.
The DA’s office earlier this month also said a dog was injured in the attack.
FOX31’s legal analyst Christopher Decker explained to FOX31 the process the DA went through amending the charges, saying it’s not a surprise how many victims have been found.
“It’s not surprising that the ongoing investigation revealed additional individuals who were present at the time of the attack,” Decker said. “The prosecution has now amended these charges multiple times to now include all the individuals who are subject to this horrific act by Mr. Solomon. So, the number of victims have increased and indeed the charges against him have increased with the death of the unfortunate victim.”
Colorado Gov. Jared Polis on Monday morning released a statement about Diamond’s death, saying, “I am devastated to hear of Karen Diamond’s passing. This loss is deeply felt by the Boulder community and our entire state, particularly within our strong Jewish community. My heartfelt condolences go out to her friends and family. Karen was taken from us too soon, and we mourn her loss while remembering her life and the impact she had on those who loved her.”
The district attorney’s office said Soliman’s next state court date is schedule for July 15.
Decker said these new charges likely will not change anything procedurally for the case, just the potential outcome.
“Mr. Solomon has been charged. He has a preliminary hearing coming up in a few weeks and these new charges will be wrapped into the existing prosecution,” Decker said. “So, for all intents and purposes, this is the same case now with more serious consequences facing Mr. Solomon.”
Soliman is also charged with federal hate crimes and pleaded not guilty last week in federal court. FOX31 reached out to the U.S. Attorney’s office about if they would update any charges as a result of Diamond’s death, but the office declined to comment.
