According to sources, quoted by India Today, the “tunnel view” method allows investigators to combine multiple forms of digital and forensic evidence into one detailed timeline.
The agency is studying CCTV footage, mobile phone records, Wi-Fi logs, internet activity, call detail records and smart-device data linked to the house. Investigators are also mapping every room of the residence to create a virtual model of the crime scene.
Officials believe this process can help identify who moved through different parts of the house, what activities took place before the incident, and whether there were any suspicious gaps or attempts to alter evidence.
The technique is often used to digitally recreate a person’s final known movements and interactions.
