Aisha Nevell-Johnson, 46, was killed on January 9, 2021 in Chicago during a multi-location shooting spree that began in Hyde Park and extended to Evanston. The gunman, identified in reports as 32-year-old Jason Nightengale, first shot a University of Chicago graduate student in a parking garage, then entered an apartment building where Nevell-Johnson was working as a security guard and shot her and a 77-year-old woman retrieving mail. Nevell-Johnson died of her injuries; the older woman was critically wounded.

The attacker continued by car, killing a 20-year-old man at a convenience store and wounding other civilians, including an 81-year-old woman and a 15-year-old girl. The incident ended in Evanston when police exchanged gunfire with Nightengale, who was killed after taking a woman hostage at an IHOP. Investigators noted disturbing social media posts by the shooter in the days before the attacks.

Did anyone in Hyde Park or Evanston recall unusual encounters or social media posts from early January 2021 that might shed more light on this rampage?
