In its closure report submitted at a Ghaziabad court last week, the Central Bureau of Investigation (CBI) said the agency had 'no direct evidence' to reveal what happened on the intervening night of May 15 and 16, 2008, when Aarushi Talwar and domestic help Hemraj Banjade were murdered at Jalvayu Vihar.
The agency, still groping in dark about the incident, however, detailed some "circumstantial evidence" to indicate the probable sequence of events during the night. The investigations relating to post-mortem of victims revealed that they were murdered between midnight and 1am.
The agency in its report said Dr Rajesh Talwar had gifted a digital camera to Aarushi on May 15, and after taking some photos, around 10pm, the Talwars and Aarushi retired to their separate rooms.
The CBI stated that Aarushi remained busy on her mobile till well past midnight and sometimes up to 1am. "On the night of the incident, her mobile phone was used at 21:10:25 hrs and it was switched off after that," the report said.
Also, According to the police, Dr Rajesh Talwar had asked his wife, Nupur, to switch on the internet router, which was in Aarushi's room, around 11pm. The router was last accessed at 11.57pm. Thereafter, the internet router remained active throughout the night with small gaps. The last activity on it was at 3.43am when the router was ultimately switched off. It was switched on again at 6.01am.
The report also said that the scene of crime in Aarushi’s room as well as on the roof top was found “heavily dressed”.
