Crime scene recreation is under way at the southeast Delhi residence where the alleged rape and murder of the 22-year-old daughter of a senior IRS officer took place on April 22.Police sources on Saturday said that as part of the ongoing probe into the case, the investigators are working to piece together the sequence of events.The iPhone stolen from the victim has been recovered from a park, while police have also conducted a potency test as part of the rape investigation, said the source.“Crime and forensic teams have been recreating the sequence of events inside the house for the past two hours and the exercise is still underway to establish how the crime unfolded,” the source said.Access to the house has been cordoned off, and heavy security has been deployed in and around the premises.The 22-year-old woman, an engineering graduate and UPSC aspirant, was raped and murdered at her residence in southeast Delhi’s Kailash Hills locality on Wednesday morning.This comes after investigators found that the accused, Rahul Meena, who had been a domestic help at the residence, used his familiarity with the house layout and access points to enter the flat.He allegedly went to the rooftop study room where the woman was studying, attacked her with a heavy object, raped her and dragged her downstairs to use her fingers to open a biometric locker and steal cash.The autopsy confirmed strangulation as the cause of death and found multiple injuries, including a nasal bone fracture, indicating a struggle.“He fled after changing clothes and slippers, and reached Palam Railway Station to catch a train to Rewari in Haryana. When he failed to catch the train, he booked a hotel in Dwarka, from where he was arrested. More than Rs 1 lakh in cash and stolen jewellery were recovered from his possession,” police officer said.As part of the probe, police took the accused to Palam railway station, where he had first gone after the crime, and will also take him to the Dwarka hotel where he stayed briefly before being arrested, sources said.Investigations have also revealed that Meena was known for aggressive behaviour in his native village in Rajasthan.“During the inquiry, we came to know that Meena and his father were known in their village for their aggressive behaviour. Our team is there. They are told that his father is an alcoholic and Meena is addicted to online games,” a police source said.Sources said police are planning a detailed psychological assessment of the accused to evaluate his mental state and behavioural patterns, noting that he has exhibited psychopathic tendencies and a history of violent conduct.“Police are now planning a detailed psychological assessment of the accused,” a source said.He said Meena was addicted to online betting and card games such as “teen patti” and had lost over Rs 7 lakh in the last few months, which drove him to frequently borrow money to sustain the habit.Meena, who had been employed as a domestic help at the house, was fired over financial misconduct. He returned to his native village and told his parents that he had left the job, the police source said. “He never told his parents that he was sacked,” the source said.A senior police officer who interrogated Meena told PTI that he is remorseless and told investigators that the murder “just happened” in a fit of rage.He told the police, “agar didi paise de deti to aisa nahi hota” (if sister (the victim) had given the money, this would not have happened), the officer said.“Chori karne ka afsos nahi par marna nahi chaiye tha, ho gaya” (I don’t regret committing the theft, but I shouldn’t have killed her. It just happened), Meena told interrogators, according to the officer.Sources said the accused displayed a strangely calm demeanour after his arrest, showing no remorse.“During questioning, he was quite casual. He acted as if everything was normal. Usually, when a person commits a heinous murder, they would display some anxiety, anger, restlessness or remorse. Meena was very casual,” said a source.He said the accused did not react much and only repeated that he wanted money to clear his debts. “We asked him if he regrets what he has done. Meena replied that the family was like god to him, but he wanted money,” the source said.The psychological analysis may involve clinical evaluation by experts to assess aggression levels, emotional responses and personality traits, including indicators linked to disorders such as anti-social personality disorder, sources said.Investigators are probing whether the crime was premeditated, with officials saying Meena’s psychological profiling will help understand his mental state and reconstruct events.A search is under way for his phone, which police said he had pawned for Rs 20,000. An officer said that if the phone is found, it could be a “breakthrough” in tracking his contacts. Police are also examining his two social media profiles and chats.
