Joseph Griffin, 78, was killed on June 10, 2022, in his home in Rex, Georgia, after an argument with his son during a visit to celebrate Griffin’s birthday. The son, 38-year-old Brandon Williams-Griffin, allegedly shot his father and fled the scene in a mint green minivan, prompting a multiagency search that crossed state lines when investigators learned he might have gone to Michigan.

Family members raised concerns about Williams-Griffin’s mental state; a brother, Joe Griffin Jr., said Williams-Griffin suffered from mental illness and had reportedly made unusual claims, including that numbers on a license plate instructed him to kill his father. U.S. Marshals, Detroit police and Clayton County officers arrested Williams-Griffin at an auto auction in Detroit, where he was reportedly planning to buy a car.

Williams-Griffin was charged with malice murder, aggravated assault, possession of a weapon during the commission of a crime and being a convicted felon in possession of a weapon, and arrangements were made for his extradition to Clayton County to face prosecution. Does anyone have information about Joseph Griffin, his family, or that day in Rex that could help the investigation?
