Why didn't this girl's parents pull her out of school?

A college student was dating this guy. He started getting abusive. She finally broke up with him.
Then he started stalking her.
In this 1 hour program it was so obviously escalating into the danger zone.
She told her mom and dad.
She went to the police.
This went on for a year.
When she returned from a date the stalker shot her point blank.

I believe I would have pulled her from school and gone into hiding.
