A 17-year-old Hampton High School student, Dalton McCullough, was shot to death during a domestic dispute at a home on Wycliffe Drive in Locust Grove, Georgia, on the afternoon of Tuesday, May 5, 2015. Dalton had gone to his girlfriend’s house; an argument escalated and witnesses say neighbors heard a gunshot and the girlfriend’s screams. A neighbor checked for a pulse but Dalton was already dead when Henry County Police arrived around noon.

The girlfriend’s 15-year-old brother, Jared Lyon, was detained at the scene and later charged as an adult with felony voluntary manslaughter. Jared and his sister said he fired one shot with a handgun kept in the home, claiming he acted to protect his sister. Jared’s attorney says Dalton had a history of a violent temper and that Jared feared for his safety; friends of Dalton described him as a great guy and held a candlelight vigil at the high school.

Was anyone in the neighborhood aware of prior tensions between Dalton and the family that afternoon?
