Mystery Caller?

My theory about the mystery caller could be that it is the same girl who was raped. To get back at her attacker(adi or Rudra) she could have faked her own murder to send the attacker to the gallows. Finding the girl alive at this stage could make MJ a free man without much of the past being revealed. I certainly dont want MJ back in jail. The interaction of Tara & MJ is what has us hooked to this show.
