CBI teams got down to a systematic investigation on Monday. Sources said teams have been formed to question people who either have links with the Talwars or were known to Hemraj. Questionnaires have been prepared for the purpose.
Senior officials accompanied by forensic experts examined the scene of crime again and questioned the family members and the neighbours. The forensic team cut out the plaster from the terrace wall where a bloodstained palm print was found.
After a medical examination, Dr Rajesh Talwar was handed over to the CBI, said VK Singh, the Dasna Jail superintendent. Talwar was taken to the CBI headquarters for questioning.
CBI also questioned Dr Anita Durani on Monday. Durani, sources said, was questioned on the kind of relationship she had with the Talwars and the time when she came to know about the murder.
Another CBI team questioned Krishna, a compounder at the Talwars clinic, and Jeevan, Hemraj’s son-in-law. Teams also questioned Umesh, Talwar’s driver, and Bharti, the other domestic help. “Talwar would be taken to his house to know the sequence of events.,” an official said.
CBI teams also spoke to Noida police officers. Investigators are also trying to retrieve as much information possible from Aarushi’s CPU and Talwar’s laptop.
CBI sources said according to their initial investigation, there is a possibility that the Noida police may have botched up the case.
“The scene of crime was completely destroyed and no evidence was picked up from the spot. The fingerprints weren’t picked, the floor of the house was allowed to be washed, things in Aarushi’s bedroom were moved. It points to major lapsed on part of the police,” a source said.
The sources said the case wasn’t as complex as the Noida police claimed it to be and would have been worked out by now had the investigators handled it better.
