Jun Zhang, 30, was found fatally shot on the front porch of a home in the 800 block of South Plum Grove Road in Palatine at about 6 p.m. on November 17, 2023. First responders pronounced him dead at the scene. Zhang had come to the United States from China, studied at Indiana University, and was employed by Weichai America Corporation in Rolling Meadows; he was recently engaged.

Detectives recovered video and by January 2024 released images of a dark-colored SUV believed connected to the shooting, described as a 2017–2020 Nissan Rogue or Murano. Police renewed appeals for tips as the case reached its first anniversary, reiterating a timeline of a quiet porch and a sudden gunshot. No arrests had been announced and no suspect publicly named as of that anniversary; the investigation remained open.

Did anyone see a dark-colored Nissan Rogue or Murano in the area that evening or recognize the route Zhang took home?
