HIGHLAND PARK, Ill. — A threatening, antisemitic letter discovered in a mailbox in Highland Park’s Braeside neighborhood on Sunday evening triggered a significant police and hazmat response, officials said. Federal investigators are assisting in the case.
Local police received the report at approximately 8:30 p.m. on June 15 after residents on the 900 block of Marion Avenue found the letter in their mailbox. They summoned a hazardous materials unit amid initial concerns of a chemical threat.
Authorities, including the FBI and Illinois’ State Terrorism and Intelligence Center, responded alongside local police. The letter was tested and deemed non‑toxic, and the scene was cleared by 10:08 p.m.
Highland Park Mayor Nancy Rotering described the incident as “an antisemitic crime” that has “shaken many of us.” She reaffirmed the city’s commitment to inclusivity and protection of its longstanding Jewish community, stating, “We will not be intimidated. We will not be silent.”
The city announced increased patrols in Jewish‑affiliated sites following what it described as a rise in global antisemitic activity.
Rebecca Weininger, deputy regional director for the Anti‑Defamation League’s Midwest chapter, called the letter “vile” and warned of “record levels of antisemitic incidents” nationwide. She emphasized the need to distinguish between protected criticism and hate‑motivated threats.
Residents expressed shock and concern. “I thought about maybe not sending my son to camp today at his Jewish school,” said neighbor Kacey Heller.
Local police are working closely with federal partners on the investigation. The community has been urged to report any suspicious activity to officials.
