Defence in Aarushi Talwar murder case on Friday sought to punch holes in CBI claim that Rajesh Talwar was awake on the night of the crime and had used internet connection at regular intervals, saying the probe agency did not provide technical details to the expert who was inconclusive about the use of router.
Tanveer Ahmed Mir, lawyer for the dentist couple, argued in the special CBI court that to prove its internet router theory, CBI "never sent computer seized from Talwars' home to experts to ascertain whether it was on or off with small gaps in the intervening night of May 15-16, 2008."
Rajesh Talwar, during the recording of his statement, had said that he went to sleep after 11.30 PM and did not use Internet.
"Why has the probe agency so far did not reveal which sites Talwars was using on internet?" Mir asked.
To confirm internet router activity, whether it was switched on or off with small gaps, it is required to examine detailed ICP log, detailed computer log and router or modem log, but "these details were never provided to experts by the CBI," the lawyer said.
"Although CBI seized computer from Talwars' house, it did not seize router and modem logs from there.
"That's why, CBI's theory of internet router activity was repeatedly switched on or off get demolished here," Mir told the court.
The lawyer added that probe agency had sent ICP log not "detailed ICP log" to Bhupender Singh Awasya, an expert of service provider, to "fully" confirm? whether router was switched on or off with small gaps.
"CBI provided brief ICP log to Awasya. Awasya in his statement said that he could not reach any conclusion till he is provided with computer log and router or modem logs. Even thereafter, it didn't provide him with these details," Mir said.
Mir also argued on blood stains on stairs, railings and terrace door.
On May 16, 2008, around 13 persons, including Noida police officials, Talwars' neighbours, visited dentist couple's home, but only three persons-- the then Noida SDM Sanjay Chauhan, Dr Rohit Kocchar, Dr Rajiv Varshney- noticed something different there, he said.
"Statements of Chauhan, Kocchar and Varshney contradict each other. Chauhan said that he noticed blood spots or wiped blood spots on stairs while Noida police sub-inspector Sunita Rana said in her statement that stairs were clean and didn't have any blood spots or any wiped blood spots there.
"Chauhan was even not spotted at Talwars' house by other people present there. So his presence is questionable," Mir said.
Kocchar had said in his statement that he saw wiped foot prints on the stairs, but Varshney said that he did not see any footprints there.
Additional Sessions Judge Shyam Lal fixed November 6 for further arguments.
