Your point is a good one. These are teenage kids. They do some inexplicably stupid stuff now and then. I know I did my fair share and learned and lived. I don't think I can fault the father based on the story given. The daughter may be in some trouble. This is a tragedy for all involved but I'm not sure if anyone goes to jail for it.
Certainly the teenage boy should have been exceedingly polite, respectful, conciliatory, apologetic and obedient to the father. He may have immediately suspected his daughter of lying about knowing who he was or why he was there. His reaction to her denial of knowing him may have ultimately been his undoing when the father went into protection beast mode.
