On September 6, 2015, 26-year-old Demario Tompkins was killed after a traffic dispute on the I-96 service drive near Greenfield Road in Detroit. Tompkins was a passenger in a black Dodge Magnum that had been bumped by a vehicle described as a possible white Chevrolet Impala. Both vehicles exited and stopped at a red light, words were exchanged, and as the light turned green shots were fired from the suspect vehicle into the Dodge Magnum. Tompkins was struck and died; his young child was also in the car at the time.

Family members publicly pleaded for information after the shooting and Crime Stoppers of Michigan offered a cash reward. The suspect vehicle was described as a newer-model white Chevrolet Impala, possibly four-door. There have been no reports of an arrest or identification of a suspect in the case.

Anyone who was on I-96 near Greenfield Road that evening or who has information about the white Impala is asked to come forward.
