There is a victim.
That victim is not Radha.
There was a rape or else the police would not have filed a rape complaint.
There is a dead body and there is a murder rap.
Only thing missing is the identification of THE VICTIM.
So, the case will be reopened for fresh investigation.
The Accused
ALERT: This is purely based on conjecture due to the dialogues.
MJ himself must've surrendered to police and must have claimed that he is the one that committed the crime [no matter what the reasons]
This must be purely based on the fact that he was made to believe that the dead gal is RADHA.
So, now that RADHA is alive and the unknown gal is yet to be identified, what is the status of the case and what is the status quo regarding his sentencing?
No doubt, there was a crime. So the charge sheet is still valid until such time there is a fresh charge sheet filed.
Is MJ still guilty?
Yes! Absolutely until further evidence pops up in the fresh investigation that the police conduct and they find another suspect.
His bail can be extended though as police themselves need to start a fresh investigation and then file a fresh charge sheet.
Can MJ now claim that he took the blame on himself under duress and that he was mislead into believing that the victim was Radha. He can claim that but the onus of proving he did not kill the other ANONYMOUS gal still rests with his defence team.
Conclusion
So all in all, we've just traded one mystery for another, now with more meat of trying to identify the real victim, the real rapist and the real killer and how all that is tied to the main story of the three main leads, {IF AT ALL the makers want to GO THERE, I aver]
