The Special Investigation Team of the CBI, which is probing the Sushant Singh Rajput death case, is leaving no stone unturned in finding the truth behind the actor death. While the Mumbai Police had declared it a case of suicide, the CBI is now investigating other angles to it too. Apart from seeing if Sushant died using the green kurta as said by the Mumbai Police or a bathrobe belt, which was recovered from his room, the CBI team will have to rely on the 20 per cent remaining viscera of the actor to solve the mystery behind Sushant Singh Rajput's death.
