Andrew Williams was 29 when he was shot to death outside his home on Hartrey Avenue in Evanston, Illinois, on July 26, 2020 — just hours before what would have been his 30th birthday. Police say two masked gunmen got out of a vehicle and opened fire, striking him multiple times. The Evanston Fire Department transported Williams to Evanston Hospital, where he was pronounced dead.

Investigators treated the killing as possibly retaliatory, noting a fatal shooting the day before on July 25, 2020 — 21-year-old Deashawn Turner was killed in the 2200 block of Emerson Street, near Williams’ home. Authorities said the incidents may have been tied to a feud between rival street gangs, although it was not clear if Williams and Turner knew each other.

On August 7, 2020, three men were arrested and charged with first-degree murder in Williams’ death: Ronald Green, 23, of Evanston, and brothers Terrence Hooper, 23, and Tyree Hooper, 22, of Sauk Village. Prosecutors said evidence included surveillance footage, GPS data and witness identifications; witnesses identified Green and Tyree Hooper as the shooters. All three were held without bond on the murder charge.
