.After being released from Jail , Rajkumar alleged CBI of torturing him. In an interview he said " “Inspite of my requesting them to, the CBI never asked me about any missing mobiles or murder weapon, during my two narco tests. A CBI official showed me much of one of the two compact discs they made out of my tests. However, this did not have any reference to any mobiles or weapons. Even otherwise, they never asked me about any missing mobiles, but kept asking me to become an approver to frame Krishna and Mandal. The CBI wanted me to say, on camera, that Krishna and Vijay Mandal committed the murders. But, I refused. At times they would stretch both my legs out on the sides, level with the ground, and two men would sit on each leg to keep them that way. “It was agonisingly painful,” he said. He also claimed that CBI officials would tell him, “We will throw you from the fifth floor and say you committed suicide. Trying to scare me was one of the ways they tried to pressurise me.”

"Sex. Illicit affairs. Murder. Indian media, which combines British tabloid sensibility with U.S. cable’s cutthroat competitiveness, snapped it up and fed it to a gossip-hungry audience, catapulting the crime to the top of the news cycle and making Aarushi a household name.For months, media feasted on leaks from unnamed police sources. They were scandalous, accusing the Talwars of extra-marital affairs, incest, swinger parties, wife-swapping and an “honour” killing. As the whispers grew louder, the well-to-do professionals morphed into extravagantly wealthy deviants who, if allowed, would buy their way out of murder.
A prime-time television drama added a plot twist, featuring the murder of a rebellious 16-year-old girl whose kohl-rimmed eyes were just like Aarushi’s. The murderer, of course, was the father." Thestar.com -The murder mystery only served as a source of raising the TRP. The media was neither concerned with the reputation of the thirteen year old nor the bereaved family members.This further complicated the murder mystery because it did everything but plant preconceived notions in the minds of the viewers.Any view contrary to the much believed opinion of parents being the murderers was considered to be wrong.
Noida Double murder mystery is not only a case of a teenager losing her life or a domestic help's decomposed body, found a day after a girl who had everything live for was found dead.It is a story of shattered hopes , it is a story of people who ceased to believe in Justice , who felt betrayed as Indians.It is the story of an impotent investigation bureau , that was unable to submit an adequate and satisfactory closure report.A closure report that was a masterpiece of insinuation and self-contradiction.It is a shock that an investigation system can fail so badly.Once , we used to cherish our pride in the country.Now we grieve at the loss of that pride.It is a story where "justice was not only delayed.But also denied."
Even five years later , justice is a far fetched cry.
