Well by tracked, you mean stalked, a enchanted item, programed to let her know when danger is near would be a great way to warn her when there near, and they would catch on that she is some All knowing creature :L but if she is running from someone who needs her for something important it might not work because they want her to know there around.
There are two types of stalkers, ones who follow you because you 'hot' or your 'sexy' these are sexual preditors and should be reported.
Now this other type of stalker is a little hard to understand. i will try though :). Okay they idolise this person, this person is a God to them. Now eventually they will force there way into your friends life, they believe that the reason she has whatever is because of them. Eventually they kill themselves or the object of there affection.
Decide if it's a stalker or not :)
if she's running from the law, as mentioned, the universe works in mysterious ways :)
