During the polygraph test on Thursday, Aaftab Poonawala, who is accused of killing Shraddha Walkar, was asked if and how he committed the murder, where he hid the evidence and questions about his childhood and family, among other things.
Earlier, police sources said they had found around 10-12 “sharp objects”, including knives, blades, saws and other tools, from the couple’s Chhattarpur Pahadi flat and the Mehrauli forest over the past week. Continuing their search for evidence in other states, a Delhi police in Mumbai’s Vasai searched through a creek in Bhayandar to search for Shraddha’s mobile phone, which they suspect was destroyed by Aaftab.
Aaftab was taken to the Forensic Science Lab (FSL) in Delhi’s Rohini for the first session of the polygraph test in the afternoon and left with police at around 8 pm. Sagarpreet Hooda, Special CP confirmed that the test had started.
An official from the FSL said: “The aim was to ascertain the locations of the murder weapon, body pieces and Walkar’s phone. The questions were mainly about the couple’s history, Poonawala’s early life, childhood, family, relationships, if/how he killed Walkar and hid the evidence, etc. He was cooperative and gave all the answers. The results will be analysed and compiled. We’ll share the observations and report with police.”
Forensic experts stated that the polygraph test would take a few hours to complete. “We check the health of the person before starting the test. After that, the test is conducted, but we take breaks so the person does not feel anxious or pressured,” said an officer.
Earlier, the Delhi Police had taken Aaftab Poonawala for pre-analysis questioning but had to delay the exercise after he complained of fever.
Earlier, police had asked permission from a Delhi court to extend Aaftab’s custody and conduct polygraph and narco-analysis tests on him. The narco test will most probably be carried out next week, said police.
On weapons recovered, a police officer said: “We are checking them for blood traces. Poonawala had said he used two-three mini-saws to chop Walkar’s body into 30-35 pieces in the bathroom. We haven’t been able to find the exact weapon yet… We are verifying his claims.”
Delhi Police team also traveled to Maharashtra’s Thane to conduct searches. “As he came to Mumbai after Walkar’s death, he may have dumped her belongings and other evidence in Vasai or Thane,” said an officer. Delhi Police said they also recorded Poonawala’s father’s statement. As per Walkar’s family and friends, Poonawala’s family allegedly knew about the violent fights between the couple, said police. “His father said he doesn’t know anything about the murder. He said Poonawala would rarely talk to them. We are trying to get details on their relationship and Poonawala’s behaviour,” added the officer.
On the search for Shraddha’s mobile phone in Mumbai, a police source stated: “Poonawala claimed he disposed of her SIM card in Delhi and threw her phone in the creek at Bhayandar. We have learnt he had come back from Delhi to help his parents shift to a new place from Vasai to Mira Road. While crossing the creek in the train, he is believed to have thrown the phone into it.”
