New revelations are happening every day in Delhi’s Shraddha murder case, the second session of polygraphy examination of Aftab Amin Poonawalla, accused in the Shraddha Walkar murder case, began on Thursday at the Forensic Science Laboratory in Rohini. The same officials said that the investigation could not be done on Wednesday as 28-year-old Poonawalla had fever and cold. An FSL official said, “Police brought him here and the process of polygraph test has started.
The delay in this investigation has also delayed the Narco investigation of Poonawalla. In a polygraphy test, physiological activities such as blood pressure, pulse and respiratory rate are recorded and these data are used to determine whether the person is telling the truth. Whereas, in Narco test, the self-consciousness of the person is reduced so that he can speak freely.
What is polygraph test
In the polygraph test, the person’s heartbeat, pulse, breathing movements are noted and related case questions are asked. On giving a false answer, the person’s heartbeat, pulse and breathing become irregular, due to which his answers are considered right and wrong. Let us inform that when the accused Aftab was presented before Metropolitan Magistrate Aviral Shukla on Tuesday, during this time the custody of the accused was extended for four more days. On the other hand, when the judge asked Poonawalla, ‘Do you know what you have done’, Poonawalla boldly replied in English that it was a heat of the movement and he did not do it “intentionally”.
