Griffin had been shot twice while still in the car; both had been shot once in the back of the head, and both were fully clothed. A blood-soaked patch of earth near the car suggested to police that they had been killed outside the car and placed back inside. Congealed blood was found covering the running board, and it had flowed through the bottom of the car door. A .32 cartridge shell was also found, possibly shot from a Colt pistol wrapped in a blanket.
