S1·E180 The Impossible Murder - Part 2

All the evidence seems to point to Abhijeet being the killer. But a forensic ballistic investigation of Rakhi's shirt shows that the bullet hole does not line up with how she was allegedly shot. Further investigation proves that Abhijeet could've blacked out while he was locked in the room with her. The final nail in the coffin comes when it turns out that the gun that Abhijeet was found holding is not actually his. Could it be that he is being set up? CID is on the case.
