Casey Thomas Lucas, 30, was fatally shot in the early morning hours of December 3, 2016, in a Super 8 Motel room on Bell Road in Antioch, Tennessee. He was in the room with several people, including his girlfriend, when an altercation broke out and ended in gunfire. His girlfriend flagged down passing officers after the shooting.

Investigators identified 33-year-old Antonio M. Jackson, an acquaintance of Lucas, as the alleged shooter and said robbery was believed to be the motive. Another man in the room told authorities Jackson had pistol-whipped him, causing a facial cut that required hospital treatment. Jackson surrendered to the Metro Nashville Police Department on December 6, 2016, and was arrested and charged with criminal homicide; he was held on an $80,000 bond.
