The Stolen Necklace - Part 1

While patrolling the streets, CID officers encounter one man chasing another. The first man claims he was doing so because he heard a gunshot and then saw the other man running away from the scene. Upon investigation, CID finds that a houseworker has been shot trying to prevent a necklace worth 50 lakh rupees from being stolen from a couple's home. The man trying to flee the scene is held in custody as a suspect, but with no forensic evidence being left on the scene, there is no way to prove his guilt.
