On the evening of November 6, 2013, a mass shooting at Al’s Place Barbershop on the east side of Detroit killed three men. Kevin Perry, 40, was among those fatally wounded when gunmen opened fire with high-powered rifles, spraying about 30 rounds into a back room where a dice game was reportedly underway. The other two dead were 61-year-old Joezell Williams and his 29-year-old nephew Bryan Williams; several patrons were also injured.

Police described the barbershop, in the 5000 block of East Seven Mile Road, as a front for illegal gambling and attributed the attack to a feud over those operations. Authorities called in a joint local-federal task force and identified Larry Walker II, also known as Larry O’Neil Walker II, as a primary person of interest; he was later arrested after ramming an unmarked federal vehicle while wearing body armor and was convicted in April 2014 of assaulting a federal officer in that confrontation. No murder charges had been filed in connection with the triple slaying as of the last report.

Did anyone in Detroit at the time have information about activity at Al’s Place or the gambling operations there?
