Unlawful Acts and Community Security Updates

In the heart of Boulder, Colorado, a tragic incident unfolded on June 1 during a peaceful walk organized by the group Run for Our Lives, advocating for the release of Israeli hostages held by Hamas in Gaza.

Karen Diamond, the president of the Boulder University Women's Club and an active member of the community, was one of the victims. Officially reported to be 15 people, including Diamond and a dog, were burned in the attack.

Upon arrival, first responders noted burns on Diamond and she complained of shoulder pain. She was immediately taken to the hospital for treatment, where she received skin grafts, shoulder surgery, and later, hospice care. Despite the medical efforts, Diamond passed away on June 25 due to third-degree burns and related complications.

Dr. Meredith Frank, a Boulder County Coroner's Office forensic pathologist, ruled Diamond's death as a homicide caused by both her burns and complications arising from her hospital stay.

The attack also left Diamond with a broken arm.

Mohamed Sabry Soliman, aged 45, has been charged with two counts of first-degree murder in connection with Diamond's death. Soliman, who has a history of violent actions related to political protests, 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, one count of animal cruelty, 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 Boulder County District Court and federal court.

Soliman's federal trial is set for June 1, 2026. His arraignment is scheduled for 1:30 p.m. Sept. 9 in Boulder County District Court before Judge Nancy Salomone.

The attack has had a profound impact on the Boulder community. Diamond was deeply involved in her synagogue and various community organizations, including the Boulder Bridge House. In the wake of the tragedy, Boulder Run for Their Lives has stopped publicizing its events, citing safety concerns.

As the community mourns the loss of Diamond, they also stand united in the pursuit of justice for this senseless act of violence.
