Corey Shannon, 33, of Dallas was killed on June 29, 2014, while a passenger in a vehicle stopped at a gas station. Police reports say an argument between Shannon and the driver, 41-year-old Ranji Charles, escalated and Charles allegedly shot Shannon, then fled, leaving Shannon’s body behind. Charles was later found with a gunshot wound to the face and hospitalized in critical condition; he was charged with murder and held on $500,000 bond.

Investigators tied Charles to another slaying earlier that day, and the case included multiple charges beyond Shannon’s death, including aggravated robbery and a capital murder count in the killing of his wife, Veronica Sauels. Witnesses reported hearing a gunshot and seeing Charles’ car crash into a fence before he shot himself. The motive is described as unclear, though the argument between Charles and Shannon is reported as the immediate trigger.

If anyone knew Corey, was at that gas station, or has information about the events of June 29, 2014, please come forward.
