Jeffrey Brinson, a 32-year-old African American man, was found with multiple gunshot wounds and died on October 14, 2016, in Chicago, Illinois. Reports say he was shot several times at close range in a neighborhood with high crime rates, and the circumstances suggested a targeted attack.

The Chicago Police Department opened an investigation that has faced obstacles: witnesses were reluctant to come forward and investigators encountered a lack of physical evidence. Several persons of interest have been identified over the years, but no arrests have been announced and the case remains open. Brinson’s family has pushed for more resources and continued attention to the investigation.

What information about Jeffrey’s last known movements or people he saw that day might help detectives move this case forward?
