New Delhi: It is expected that the probe team of Shraddha Walkar's murder would go for accused Aaftab Amin Poonawalla's brain mapping if both polygraph and narco test turn inconclusive, IANS reported citing sources.
"Polygraph test report of Aaftab will be submitted within two days, and his narco test is expected to be presented either on Thursday or Friday. After the narco test, it is up to the investigators to demand brain mapping after they do not get answers expected by the accused," IANS was told by a Forensic Science Laboratory (FSL) source.
It was on Tuesday that the polygraph test finally ended, which was after six sessions.
"He (Aaftab) has confessed to killing Shraddha and disposing of her body parts in the forest areas. He also had relationships with several girls," sources said.
Meanwhile, the FSL officials said that the investigators of the case were being regularly updated.
"The polygraph report will have all the questions that were asked to Aftab and his responses to them. For every answer, the FSL officials will share their opinion, based on readings, whether Aaftab was truthful or lying," an official said.
On Tuesday, a court allowed Delhi Police Police to conduct a narco test on the accused on December 1 and 5.
IANS learned that Aaftab was deceptive and tried to mislead the interrogators during interrogation; therefore, a polygraph and a narco test were imperative.
Narco analysis involves the intravenous administration of a drug (such as sodium pentothal, scopolamine, and sodium amytal). Also known as the truth serum, the narco test sends a person into various stages of anaesthesia.
