Sorry man, u can not track a person without the persons permission(have the person install an application directly or indirectly on the phone) or have the persons call log tracked to the last base station the person used to make a call(Triangulation-This requires access to the subscribers mobile network and permission from the user you need to track). In most cases, it is not legal to track a person without the users permission. You best solution is to contact the mobile network directly. They can track anybody.
