Omar Maslat, 57, was killed on April 2, 2014, in Chicago while working as a convenience store cashier. According to police, the fatal shooting happened during a dispute over merchandise outside the store when Maslat tried to block a man’s path; he was shot in the chest and taken to Advocate Christ Medical Center in Oak Lawn, where he was pronounced dead shortly after 7 a.m.

Police charged 31-year-old Joey Jones with first-degree murder in Maslat’s death. Jones was also charged with attempted murder in a separate shooting less than four hours later, when 50-year-old Brion Payne was shot in the head at a Dunkin Donuts in Uptown Chicago and taken to Advocate Illinois Masonic Medical Center in serious condition. Officers located an alleged getaway car, a Ford Crown Victoria, near Jones’s home and questioned him for 12 hours before filing the charges; he was ordered held without bond.
