Narco-analysis on Talwar couple draws a blank for CBI

The CBI had carried out narco-analysis test on Nupur Talwar between February 8 and February 12 and on Rajesh Talwar between February 15 and 20.

The agency had already conducted brain mapping and lie detector tests of the Talwars in 2009.

"No concrete evidence could be collected even after conducting the narco-test of the Talwar couple that could help in further investigations in the case.  The test was conducted to find out if Nupur Talwar or Rajesh Talwar knew anything about the case, but they knew nothing different," a forensic scientist with the Gujarat Forensic Sciences laboratory said.

"It did not take much time to accomplish the test. All got over in a matter of two day's time. No CBI official had accompanied them," he said.

Aarushi (14) and her domestic help Hemraj were found murdered at their Noida house on May 16, 2008 but so far CBI has not been able to nail the killers.

When contacted Rajesh Talwar said, "That is what we have been telling since long. We just want Aarushi's killer to be apprehended as soon as possible. Whatever CBI told us to do, we followed it religiously. We will cooperate in future as well. It is for the CBI now to decide what should be done next."

The CBI has incurred an expenditure of more than Rs one lakh to get the test done on the Talwar couple.

Narco-analysis involves psychotherapy which is conducted while the patient is deeply sedated with medication so that inhibitions are reduced and responses are truthful.
