New Delhi: For the first time, the countrys premier probe agency, CBI, is likely to submit before September chargsheets in the sensational Aarushi murder case based only on scientific evidences rather than direct proofs for legal scrutiny.

The chargesheet for the Noida double murder case will be based on circumstantial evidences, narco-analysis and lie-detector tests, and psychological assessment, official sources said.

If it withstood the legal scrutiny, could be landmark in the countrys criminal investigation history, experts commented.

Sleuths of the probe agency had conducted three months of pain-staking examinations into the case, in which teenager Aarushi and her familys domestic help Hemraj were mercilessly murdered.

The investigations also led to the arrest of Krishna, a compounder working with Aarushis father Rajesh Talwar, and Rajkumar, helper of Talwar familys neighbour, and Vijay Mandal, another domestic helper.

The chargesheet is likely to be filed against Krishna, Rajkumar and Mandal, who was bailed out recently by a designated court despite protests by the CBI counsel saying that he may try to destroy evidence, the sources said.

The chargesheet is likely to be filed before September 13 as the CBI had made its first arrest on June 13 and it is mandatory for the investigating agency to file a chargesheet within 90 days of the first arrest, otherwise the accused can
automatically apply for bail.

According to the CBI investigations, Krishna, compounder of Talwar, emerged as "prime suspect" as his psychological assessment test and polygraph test "revealed deception on all major points relating to the crime".

Krishna was subjected to brain finger-printing and narco analysis test during which the CBI claims that he confessed his involvement in the crime along with his two other associates Raj Kumar (domestic help of Talwars family friend) and Vijay Mandal, the sources said.

According to the CBI, Krishna and Raj Kumar, arrested on June 28,and Mandal gathered at the room of Hemraj and consumed alcohol and later tried to sexually assault Aarushi.

The three, according to the CBI, talked about Aarushi over drinks and under the influence of alcohol they went into the room of Aarushi. She got up and tried to scream. She was gagged and allegedly hit by hard blunt object on her head after which they allegedly tried to sexually abuse her.

The CBI claims that this act led to an altercation between them and fearing that the parents of Aarushi might get up, they went to the terrace where Raj Kumar and Krishna had a scuffle with Hemraj in which he was killed.

On Krishna, the agency said two days before the murders, Talwar had scolded Krishna for not performing his official duties. This had led to a grudge with Krishna who openly discussed taking revenge, it added.

The psychological assessment of Krishna showed that he was having aggressive tendencies, not loyal to anyone, evasive, manipulative and hiding facts, the sources said.

"The so-called confessions of Krishna and Raj Kumar have been corroborated forensically to the extent that the blood of Hemraj (AB group) was found on pillow in Aarushis room," according to an official.

The test results would be only support to the CBI investigations in the court of law in Ghaziabads designated court as it could neither find weapons of offence or the mobile phone of Aarushi or Hemraj.

The chargesheet is also likely to give a clean chit to Aarushis father, Rajesh Talwar, who was arrested by the Noida police on May 23. He was bailed after remaining in prison for nearly 50 days.

The CBI informed the Ghaziabad court that it did not find any evidence against Talwar and that Noida Police had also not found any evidence.

It said both -- Talwar and his wife Nupur -- were subjected to polygraph test twice and later they also underwent Psycho Analysis Test and "nothing adverse was found against them".

Further, the agency carried out a simulation exercise to check the sound level at the real crime-time basis by CFSL and forensic experts before two independent witnesses by switching on both the air conditioners in the bedroom of Talwar and Aarushi.

There was no sound of either steps or opening of the door heard in the bedroom of Talwar by Physics division experts of CFSL, the source added.
