The 18 year old heard a call for help from his mother in an adjacent room in their house, and entered the room to find a masked gunman in tactical dress holding her at gunpoint. The teen shot the intruder dead, only to find he was his own (estranged) father.
He later related that his father was divorced from his mom, was a convicted felon, she had a restraining order against him, and the son sort of knew this would eventually happen. The father smashed a window to enter the house.
