What a crap situation. My wife has had a few parents show up to have words with her after their little angel got in trouble and lied about it, but nothing to that degree.
Hopefully you've already talked to your building's union rep, they should have one with you from here on out when it comes to that parent. And your administration is TERRIBLE for allowing a parent to just confront you like that. Terrible. I've got 5 active teachers and 2 retired ones in my family, so I've heard a lot (and unfortunately been through a few with my wife) and for that situation to happen... man. I'm boiling just thinking about what happened to you.
