We have also gathered significant electronic and digital leads about the case. The task at hand now is to corroborate the physical evidence with digital leads, including CCTV footage and cell phone data. The cell phone data is in large quantities and its logical sorting is always an important task. We are reconstructing the sequence of events in reverse, working backwards from the time of the murder to establish the movements and actions of the accused in the days leading up to the crime.”Story continues below this adAnother officer said, “Digital evidence by itself rarely tells the complete story. Every CCTV timestamp, mobile tower location, call detail record, handset location, internet activity and movement pattern has to be matched with statements of the accused and witnesses, physical evidence and the scene of crime. We are reconstructing the case in reverse — starting from the last confirmed event, the murder, and then working backwards hour by hour and day by day to establish where each accused was, how they travelled and what actions they took in the days leading up to the offence.”Also Read | Ketan Agarwal’s grandfather dies after brief illnessDays before they allegedly pushed Ketan off the cliff of the Lohagad Fort, Siya and Chetan conducted practice on how they will execute their plan of murder, police claimed.Police said that this rehearsal was conducted in an open space next to a club lounge in Pune’s Lulla Nagar area.
