The investigation into the rape and murder of a 22-year-old IIT graduate in Kailash Hills, southeast Delhi, led to the arrest of Rahul Meena through vital digital evidence. Police utilized a stolen mobile phone, which Meena had used, to establish a digital trail despite his lack of a personal device. After the crime, he fled with approximately ₹2.5 lakh (roughly $3,000 USD) and checked into a hotel in Dwarka, where his use of the hotel’s Wi-Fi allowed police to pinpoint his location using Internet Protocol Detail Records (IPDR). Additionally, continuous communication with a relative via Instagram Messenger provided further insights into his movements. CCTV footage corroborated the timeline of the incident, showing Meena entering and leaving the victim's residence during the suspected time of the crime. The suspect, a former domestic help for the victim's family, was familiar with the house layout and allegedly used a spare key to gain entry. Police have gathered strong evidence and continue to investigate the full circumstances of the case.
