Cynthia Trevillion, a 63-year-old teacher at the Chicago Waldorf School, was killed on October 13, 2017, in Rogers Park while walking to a nearby CTA station around 6:30 p.m. She was struck in the head by a stray bullet from a drive-by shooting; the shots came from an SUV involved in a gang-related incident and she was not the intended target. Trevillion was taken to a hospital and later pronounced dead.

Colleagues and students remembered her as a beloved, long-serving educator whose loss devastated the school community. Chicago police characterized the shooting as a tragic accident and noted it underscored the problem of gun violence claiming unintended victims. No arrests were made in the immediate aftermath.
