The Loudoun County Sheriff's Office says Caleb A. Gordley, 16, was shot by the owner of the home on the 45900 block of Pullman Court around 2:30 a.m. The house's alarm sounded, and the homeowner found Gordley on the stairwell, police say. 
Gordley, a Park View High School student, died on the scene. The homeowner's name has not been released. 
The sheriff's office says Gordley lived on the same street where the shooting took place, and that they believe he entered the home through a window in the rear of the home. 
Gordley had apparently been drinking, and a Twitter account that appears to be his did post about a party happening Saturday night. 
Shawn Gordley, the teen's father, made his comments on Twitter:

This one could very well be another murder disguised as a DGU. Being a drunk 16-year-old and entering someone's house does not merit death. But you won't hear that from the frightened and fanatical gun-rights advocates.  To them, the downside of hesitating is too much.  They shoot to kill as soon as someone dares to violate their sacred boundaries.
And naturally once the delinquent kid is dead, there's only the home owners side of the story which always includes that he felt threatened.  What he usually feels is outrage and anger that some punk would dare to do something like that. He shoots without making any effort to determine if his life is really in danger and he does so totally justified by the law and all the other self-righteous castle-doctrine proponents.
