Twisha Sharma case: CBI employs 'tunnel view' to track final moments
The 'tunnel view' technique is the method through which investigators synchronise CCTV, phone records, Wi-Fi logs, internet activity, smart-device data, forensic mapping, and witness accounts into a focused timeline to digitally reconstruct a crime's final moments.

The Central Bureau of Investigation (CBI), which is probing the death of former actor-model Twisha Sharma, has deployed what's known as 'tunnel view' investigation technique to digitally reconstruct her final moments before she was found dead at her matrimonial home in Bhopal on May 12.
The agency is creating a highly detailed, minute-by-minute virtual reconstruction of the events leading up to Twisha’s death in an attempt to decode the exact circumstances and sequence of events on the night of the incident.
The 'tunnel view' technique is a method through which investigators synchronise CCTV, phone records, Wi-Fi logs, internet activity, smart-device data, forensic mapping, and witness accounts into a single, focused timeline that digitally reconstructs the final moments of an incident.
According to sources, the CBI is integrating CCTV footage, mobile phone data, Wi-Fi logs, Call Detail Records (CDRs), and maps of rooms at the Katara Hills residence to build a virtual spatial model of the house.
The objective is to trace Twisha’s movements, determine who entered or exited specific areas of the house at what time, and establish the timeline of events before her death.
Investigators are also synchronising timestamps from surveillance cameras with phone activity and internet usage to generate a simulated visualisation of Twisha’s final hours.
Through the "tunnel view" analysis, the agency hopes to identify critical time gaps, suspicious movements, inconsistencies in witness statements, and any possible attempts to tamper with evidence after the incident.
Sources said the digital reconstruction could help investigators determine whether there was any coercion, conspiracy, or deliberate manipulation of the crime scene on the night Twisha died.
Twisha Sharma was a Noida-based former actor and model and was married to Samarth Singh of Bhopal last December. She was found hanging at her matrimonial home on May 12 under mysterious circumstances, raising suspicions of alleged foul play.
Following her death, Twisha Sharma's parents accused her in-laws and her husband of physical abuse, domestic violence, mental torture and even her "murder". They said that Twisha's mother-in-law Giribala Singh, a former district court judge, was even trying to influence the probe.
Initially, Twisha's parents even refused to conduct her funeral, demanding a second post-mortem at AIIMS Delhi. Twisha was finally cremated on May 24 after a second post-mortem was done at AIIMS Delhi.
Meanwhile, Twisha's in-laws have refuted all claims of foul play and their involvement in her death. They have rather claimed that Twisha had been behaving erratically after she learnt about her pregnancy in April and said she wanted to abort it as she did not want a child.
After absconding for 10 days, Twisha Sharma's husband Samarth Singh surrendered and was arrested in Jabalpur on May 22.
CBI ARRESTS GIRIBALA SINGH
The latest development comes a day after the CBI arrested Twisha Sharma's mother-in-law Giribala Singh.
A CBI team questioned Giribala Singh at her residence in Bhopal’s Bag Mughaliya extension area before taking her into custody on May 28. Officials said the agency is likely to produce her before a competent court to seek formal custody.
According to officials, the CBI plans to confront the mother-son duo with each other’s statements as part of its effort to probe the circumstances surrounding the 33-year-old former model’s death.
The arrest came after the Madhya Pradesh High Court quashed the anticipatory bail earlier granted to Giribala Singh by a sessions court.
In a 17-page order, Justice Devnarayan Mishra observed that "in the light of the factual aspects of the case and the allegations levelled against the respondent (Giribala Singh), the anticipatory bail granted by the additional sessions judge deserved to be quashed".
The CBI formally took over the probe earlier this week and re-registered the FIR initially filed by the Madhya Pradesh Police against Samarth Singh and Giribala Singh.
The CBI’s 'tunnel view' reconstruction marks a crucial phase in the investigation with arrests made and digital evidence being synchronised.
The agency is expected to intensify interrogations, confront key accused with forensic findings, and rely heavily on digital reconstruction to establish the exact sequence of events.
