Deon Mack was killed after being shot in a Tulsa neighborhood park on the night of June 28, 1997. He had spent the evening in a small park in the 5200 block of South 40th West Avenue; witnesses later reported an unidentified person lingering by Mack’s car and peering through the windows. As Mack approached his vehicle the stranger opened fire. He was taken to a hospital and pronounced dead the same day.

The killing remained an unsolved 1990s cold case for years, recorded in Tulsa Police Department listings as a homicide with limited details: location, witnesses seeing a person near the car, gunfire as Mack approached, and his fatal injury. In 2015 investigators identified a suspect, Irving Dwayne Stewart, then serving time in Georgia for an aggravated assault, and arranged his return to Tulsa County to face a first-degree murder charge; news accounts at that time reported he was held without bond.

If anyone was in the 5200 block of South 40th West Avenue on June 28, 1997, or remembers seeing someone near a car that night, please come forward with information.
