On November 6, 2013, a mass shooting at Al’s Barber Shop on Detroit’s east side left 61-year-old Joezell Williams dead along with his 29-year-old nephew Bryian Williams and stepson Kevin Perry. Six other people were wounded in the attack. The shooting was called an act of urban terrorism by the Detroit Police Chief at the time.

Federal agents pursued and arrested a man identified as Larry O’Neil Walker II in Rochester Hills days after the barber shop massacre; agents say he tried to ram an agent’s car during a traffic stop and was wearing a bulletproof vest when taken into custody. Walker was treated as a person of interest but was not immediately charged in connection with the murders. A second arrest was announced later in November, though the individual’s identity and specific charges were not released at that time. The motive for the attack remained unclear.

If anyone remembers events at Al’s Barber Shop that day or has information that could help the investigation, please share what is known with authorities.
