Brent Mandel Jones Jr., 27, was fatally shot on June 14, 2021, in the parking lot of an O’Reilly Auto Parts on Dedeaux Road in Gulfport, Mississippi. He was in the driver’s seat of his white SUV when first responders found him with multiple gunshot wounds; the driver’s side window was shattered and he was pronounced dead at the scene. Jones was a father and was known as BJ.

Investigators identified a suspect, Demonte Levell Williams, and said the two men knew one another. The dispute that led to the shooting was described as personal and connected to Jones’s engagement to the mother of Williams’s children. After the shooting friends and family gathered at the scene.

A warrant was issued for Williams on a charge of first-degree murder; he surrendered later that day and his attorney said he acted in self-defense. What additional information exists about the argument in the parking lot, and can anyone who witnessed the incident or knew Jones or Williams help fill in details?
