John Cassidy Williams was 22 and a former U.S. Marine when he was found shot to death on a ramp to the Southfield Freeway in Detroit on January 23, 2023. Investigators say he was shot while inside a vehicle and his body was pushed out onto the pavement, a detail that led authorities to treat the killing as not random.

The investigation produced a quick arrest: 22-year-old Rayquin Desean Patrick was taken into custody and later charged with first-degree murder. Authorities confirmed Patrick and Williams were acquainted, but the precise nature of their relationship and any motive have not been released.

Did anyone who knew John or saw activity on that stretch of the Southfield Freeway in late January 2023 notice anything that could help the investigation?
