The Central Bureau of Investigation (CBI) on Wednesday subjected Dr Rajesh Talwar, the main accused in the Noida double murder case, to a polygraph (lie detector) test.
The test was conducted at the Central Forensic Science Laboratory (CFSL) with Talwar’s consent. The Noida Police have accused Talwar of killing his daughter Aarushi and servant Hemraj on the night of May 15-16.
Test not of much help
Sources, however, said the test did not provide any further leads to the agency, which failed to arrive at any firm conclusion.
“We were surprised when he gave his consent for the test. He could have said no, citing medical grounds. Nothing much came out of the test, which could mean what he is saying is true or he is smart enough to dodge the test,” an investigating official said.
Forensic evidence holds the key
The agency, sources said, is firmly banking on the forensic evidence gathered by experts for a breakthrough in the case. “Forensic experts are working on the evidence collected from the scene of crime. The viscera report of the deceased is also awaited.
Blood samples still present at the scene of crime, suspected fingerprints, palm prints, etc, and other forensic evidence have been collected,” the sources said.
Clothes may have been washed
The blood-soaked blanket found on Aarushi’s body and some other clothes, suspected to have blood on them, have been seized. Officials did not deny the possibility that some clothes recovered by them might have been washed after the incident.
Unconfirmed reports said a palm print found on the terrace of the house could be of a man wearing surgical gloves. The area around the house is also being scanned for further clues.
A CBI team on Wednesday questioned Talwar’s family members again. Noida Police officers, their forensic experts, doctors who conducted the post-mortem, the colony security guard and retired police officer KK Gautam were also questioned. Security supervisor Shyam Sunder was also questioned.
The guard later said that since the last one month, they had stopped noting down the numbers of cars going inside the colony. Instead, they would issue gate passes, which would returned when the people left.
The CBI director chaired a review meeting with forensic experts to discuss issues relating to forensic evidence available at the scene of crime, analysis of post-mortem report and other aspects of investigation.
The agency has constituted 10 teams to look into the various aspects of the investigation.
Talwar could lead to weapon
The agency had produced Talwar’s statement recorded by the Noida Police under section 161 in court on Tuesday, wherein it was stated that he had agreed to help them recover the weapon of offence and mobile phones of the victims.
It stated that Talwar had complete knowledge as to what happened on the night of May 15-16.
