Jacquelyn Jacki Lovi Sundheim, 63, of Highland Park, Illinois, was killed on July 4, 2022, during the Highland Park Independence Day parade. She was struck down when a gunman opened fire from a rooftop in downtown Highland Park; seven people were killed and dozens more injured in the attack. Sundheim, a longtime member and preschool teacher and events coordinator at North Shore Congregation Israel, died at the scene. A memorial service was held on July 8, 2022, at the synagogue where she worked and worshipped.

Authorities arrested 21-year-old Robert E. Crimo III in connection with the shooting. He was charged with seven counts of first-degree murder, including for Sundheim’s death, and with additional charges tied to other victims; investigators say he fired more than 70 rounds from a high-powered rifle and that the attack appeared premeditated. Sundheim is remembered by the community as a devoted wife, mother, sister, and friend.
