The Aarushi-Hemraj murder case took a dramatic turn with Krishna stating that Rajkumar tried to rape Aarushi Talwar and later killed her.

Krishna, compounder at Dr Talwars clinic, said during his narco-analysis test that he along with Hemraj, Rajkumar and another person by the name Shambu had met at Aarushi's residence on May 15. They assembled at the servant quarters where they had beer together.

Krishna said that Rajkumar, a domestic help at Anita Durrani's residence, had cast an evil eye on Aarushi.

After having beer, Rajkumar went to Aarushi's room and tried to force himself on her. However, she resisted and he was forced to kill her.

Rajkumar killed her with a khukri by slitting her throat. Krishna also said during the test that Hemraj had threatened to reveal all as a result of which they were forced to kill him. He said that they took Hemraj to the terrace and killed him.

Krishna during his narco-test in Bengaluru, however, did not say clearly as to who the new peson Shambu was.

He said during the test that they cleaned the weapon and dumped it outside.

The CBI is having a tough time in taking the case to the next level. They are yet to get answers as to why the Talwars did not hear the screams when they were in the next room.

Krishna also said that the Talwars were innocent and they did not play any role in the murder.

The CBI has now launched a hunt for Shambu and are trying to ascertain what role he has played in this case.

The CBI is contemplating subjecting Rajkumar to a narco-analysis test.
