A mile from me and not quite 40 years ago a teenage son shot his father and mother to death one morning .
But since he was teenager,he was only put in juvenile detention for a few years.But the parents were just as dead as if killed by a stranger.
Awful as it sounds,sometimes a person might have to kill a family member to save their own life or that of a third innocent person. Approaching anyone while masked and holding a knife is not likely to lead to a good outcome.If a so-called prank by the Conn. youth it was a really stupid one.And considering it was a adopted or step-parent relationship there might have been deep anger issues against the man.
