The Chicago police continued their hunt Sunday for the gunman who killed off-duty Officer Areanah Preston as she returned home early Saturday to her South Side home after work, but it’s unclear why the police took more than 30 minutes early Saturday morning to arrive after gunshots were detected by the city’s ShotSpotter gunshot surveillance system.
Police say Preston, 24, was shot to death around 1:42 a.m. during a robbery as she showed up at her home in the 8100 block of South Blackstone Avenue in Avalon Park.
