The murders occurred on the morning of December 22 when the teen shot Buckley Kuhn-Fricker, 43, and her husband 48-year-old Scott Fricker, in their Reston, Va. home.

Details later emerged that the 17-year-old boy had been dating the Frickers’ 16-year-old daughter. After learning that the teen expressed neo-Nazi sympathies online, the parents attempted to keep their daughter from seeing him. After being confronted by the Frickers in their daughter’s room after discovering him there, the teen shot them both before himself.
