Colorado Governor Jared Polis speaks during a community gathering at the site of an attack against a group people holding a vigil for kidnapped Israeli citizens in Gaza oin Boulder, Colorado on June 4, 2025.
Three weeks after a Colorado march in support of the Israeli hostages in Gaza was abruptly interrupted by a scene of grotesque violence, one of the victims of the antisemitic firebombing attack that left 29 people injured succumbed to her wounds.
Karen Diamond died on June 25, Rabbi Marc Soloway, of Boulder’s Congregation Bonai Shalom, announced in an obituary. She was 81, and is survived by her husband, two sons, two daughters-in-law and five grandsons.
“There are no words to express the pain of this horrific loss of our beloved member and friend,” Soloway wrote.
The alleged attacker, Egyptian national Mohamed Soliman, now faces two counts of first-degree murder connected to Diamond’s death, in addition to 12 federal hate crimes charges and more than 100 state charges related to the June 1 attack. A Justice Department spokesperson declined to comment.
Run for Their Lives, the organization that arranges the weekly hostage marches, released a statement on Monday calling Diamond’s death “a heavy and heartbreaking moment for us.”
