A Boulder woman died because of third-degree burns and related complications that she sustained in the antisemitic Pearl Street firebombing attack on June 1, according to the Boulder County Coroner’s Office.
, 82, also broke her arm in the attack, according to an autopsy report released today.
Diamond was among the 29 people attacked when an individual threw two Molotov cocktails into a group of people participating in a walk organized by the group Run for Our Lives, which advocates for the release of the remaining Israeli hostages held by Hamas in Gaza after the terrorist organization attacked Israel on Oct. 7, 2023.
After spending weeks in the hospital, including hospice care, Diamond died on June 25.
Diamond was active in the Boulder community, serving as president of the Boulder University Women’s Club and working for her synagogue and various other community organizations, including the Boulder Bridge House, which provides services to adults experiencing homelessness.
During the June 1 attack, Diamond was set on fire and bystanders attempted to smother the flames. When first responders arrived, they noted she had burns and complained of shoulder pain, according to the autopsy report.

At the hospital, Diamond was diagnosed with third-degree burns over nearly half of her body, including on her head, neck, torso, arms and legs.
She received treatment for her burns, including skin grafts, and shoulder surgery. Just over two weeks after the attack, she was transitioned to hospice care.
During her hospital stay, Diamond developed several complications, including respiratory failure, pneumonia from being on a ventilator, a blood infection, a bleeding disorder, an acute kidney injury, urinary retention and shock.
Dr. Meredith Frank, a Boulder County Coroner’s Office forensic pathologist, cited both the burns and complications relating to Diamond’s hospital stay as the cause of Diamond’s death. Frank ruled the manner of death as homicide.
Mohamed Sabry Soliman, 45, was charged with two counts of first-degree murder in her death. He also faces 52 counts of attempted first-degree murder, eight counts of first-degree assault, 18 counts of attempted first-degree assault, two counts of third-degree assault, two counts of using an incendiary device, 16 counts of attempted use of an incendiary device and one count of animal cruelty in Boulder County District Court. He also faces nine hate-crime charges, two charges that he used a fire or explosive device to carry out a felony and one count of carrying an explosive during the commission of a felony in federal court.
Officials initially said 15 people, including Diamond, and a dog were burned in the attack.
The District Attorney’s office later identified 14 additional victims of the attack, which included people who suffered injuries while fleeing the attack and people who were not physically harmed, but were close enough to the attack to be victims of attempted murder, according to District Attorney Michael Dougherty.
Soliman will appear at 1:30 p.m. Sept. 9 for an arraignment in Boulder County District Court before Judge Nancy Salomone.
Soliman also faces federal charges. A jury trial is set for June 1, 2026.
