ANDERSON, S.C. — A South Carolina coroner says witnesses report a teenager was acting "bizarrely" before he was fatally shot by a friend's parent.

Anderson County Coroner Greg Shore tells news outlets 17-year-old Brandon Nathan Tyson, of Williamston, died Saturday from a gunshot wound to the head. Shore says Tyson and several teens attended a high school football game Friday night and then gathered at a home.

Shore says the teens report Tyson was acting "bizarrely" by tossing furniture and smashing windows. Shore says the adult homeowner then got into an argument with Tyson that led to a fight. Tyson was shot and the adult was taken to a hospital with serious injuries.

The adult's identity hasn't been released. Shore says he's awaiting a toxicology report to learn if drugs were a factor.
