New Delhi, Oct 24 : Investigators probing the brutal murder of a Swiss woman named Nina Berger, whose body with limbs and legs bound with chains was found near a school in West Delhi on October 20, took the accused, Gurpreet Singh, to the spot to recreate the crime scene on Tuesday. With this, the police are trying to understand the sequence of events that led to the horrific murder of the woman. According to sources, the examination of the mobile phone of the accused revealed that he was in touch with at least a dozen women who were also foreigners, an evidence that possibly links the case to the police's human trafficking theory. Significantly, the police discovered over Rs 2 crore in cash from Gurpreet's residence in Janakpuri. Further investigation revealed substantial financial transactions through Gurpreet's bank account, leading the investigators to notify the Income Tax authorities. These high-value transactions and the unaccounted cash raised suspicions that the case might be related to human trafficking. Moreover, the cuts and some burn marks on the victim's body also indicate that she was probably tortured before being killed. Even the locks and chains, with which the woman was found tied, were bought just two days back by the accused from a market in West Delhi. The exact shop from where these things were boughtis yet to be ascertained. Nina Berger's body was found near a school in West Delhi on October 20. Initially, there were inconsistencies in the statements made by the prime accused, Gurpreet, who was subsequently arrested in connection with the crime. His statements regarding the murder kept changing. During investigation, the police recovered various documents, including Nina's passport and visa, from Gurpreet's possession. As per Gurpreet's interrogation, he had met Nina in 2021 during his visit to Switzerland, and their friendship had developed into a close bond. Gurpreet frequently travelled to Switzerland to be near Nina. Over time, he expressed his desire to marry her, but she rejected his proposal. Nina had arrived in Delhi from Zurich on October 11 and was staying in a hotel. However, as the interrogation of Gurpreet continued, it became evident that he was attempting to mislead the authorities. /IANS
