Before slain Chicago police Officer Aréanah Preston’s mother helped pull off a cover to unveil a street sign honoring her daughter, she prayed the city would remember the ambitious, vibrant young woman she raised.

       “I promise your name will be the change you wanted to see,” Preston’s mother, Dionne Mhoon, told the hundreds gathered to remember Preston Saturday.

       City and police leaders including Chicago Mayor Brandon Johnson and his CPD superintendent nominee Chief Larry Snelling joined the 24-year-old’s family and friends to honor her by renaming the Avalon Park stretch of South Blackstone Avenue where she was killed in May.
