Aarushi murder case is one of the most mysterious cases in the crime history of India. Arushi Talwar and her servant Hemraj were killed on 16th May 2008 at Jalvayu Vihar in Noida. UP police investigated this case and found that victim’s father Dr. Ramesh Talwar has murdered his own daughter and his servant. After sometime, case has been transferred to CBI and CBI given clean chit to Dr. Ramesh Talwar and arrested some servants. But after more time CBI found that servants are innocent. CBI can not found any strong evidence against killer but they submit the closure report in court with comment that Dr. Ramesh Talwar is main suspect in this case but there is no any proof full evidence against Dr. Talwar.

Lie detector and narco tests conducted on both parents have proved to be inconclusive and on December 29, 2010, the CBI filed a closure report in the twin murders, clearing the servants but pointing a finger of suspicion at the parents. To make matters worse, on January 25, Rajesh Talwar was attacked by a deranged man with a cleaver in the Ghaziabad court premises.

Court on 09.02.2011 ordered that case should be registered against Dr. Ramesh Talwar and Dr. Nupur Talwar as prime suspect in this murder case.

Now CBI have to solved most puzzled case again.

There are many clues that says that Dr. Talwar pair were not unknown in this murder mystery and they are trying to hide some things.
CBI should ask to Dr. Talwar pairs following questions –
(1) Why they locked Aarushi’s door daily?
(2) How is it possible that if a murderer came from outside and went after murder then main door is locked from inside?
