One year after an anti-Israel attacker in Boulder, Colorado, killed an elderly woman and wounded more than a dozen people at a demonstration supporting Israeli hostages in Gaza, security is expected to be high at today’s Boulder Jewish Festival.

Police will maintain a significant security presence, including undercover, aerial, and rooftop monitoring and K9 units, the Boulder Jewish Community Center said in a statement last week. Other security measures will be run discreetly, not visible to the public.

The festival will be held at the Pearl Street Mall, near the site where a man threw two Molotov cocktails at participants of a weekly Run for Their Lives march on June 1, 2025. An 82-year-old woman, Karen Diamond, died several weeks later from injuries she sustained during the attack. Eight women and seven men were injured in the attack, some with severe burns.

The suspect, 46-year-old Mohamed Sabry Soliman, was sentenced to life in prison without parole in May after pleading guilty to dozens of felony counts.

During the festival, Boulder County will unveil a new stone marker in Diamond’s memory in front of the Courthouse, the local government said. The festival will also include Israeli dancing, art workshops, and other family activities.
