Joseph Michael Carson was 31 when he and Anthony Lee Hammond were found shot to death inside a car in a Walmart parking lot in Owosso, Michigan, on January 27, 2017. Investigators say the killings grew out of a planned marijuana transaction arranged through an online advertisement; what began as a sale turned into a robbery and both men were shot before the assailants fled.

Police identified two brothers from Grand Rapids, Otis Smith Jr. and Anthony Holloway, as the primary suspects, with Otis Smith Jr. named as the shooter. A woman who served as the getaway driver was also arrested. Prosecutors rejected a self-defense claim and the brothers were convicted in Shiawassee County Circuit Court; Otis Smith Jr. received life without parole, and Holloway was convicted and awaiting sentencing. The getaway driver was also sentenced for her role.
