Ghaziabad, April 18 (IANS) A CBI investigating officer in the Aarushi-Hemraj double murder indicated in a Ghaziabad court Thursday that plywood on walls and wooden floors in Aarushi's room could have prevented any noise from going out at the time of her killing, a lawyer said.
The probe agency's superintendent A.G.L. Kaul, during his cross-examination before Central Bureau of Investigation (CBI) Special Judge S. Lal, was asked if during investigation they could find any reason why Aarushi's dentist parents allegedly did not get alerted when she was murdered in another room in their Noida house.
Kaul admitted that the partition wall of Aarushi's room was made of bricks and it was laminated with plywood and the flooring was also wooden.
Defence counsel Manoj Sishodia, who cross-examined Kaul, told IANS: "Earlier another CBI officer Vijay Kumar admitted that the probe agency conducted a sound test in which it was concluded that no noise could have gone out of Aarushi's room."
The defence lawyer said Kaul during the cross-examination admitted that no investigation related to the call details was carried out in connection with the seized mobile phone of Aarushi.
The IO admitted that no call detail records were tracked and no service provider's assistance was sought to verify the call record details after Aaurushi's mobile phone was recovered from a park several months after the killing, the defence lawyer said.
Kaul's cross-examination would continue for the third day April 22.
Earlier April 16, the IO said that on the basis of the circumstances, he was convinced that dental couple-Nupur and Rajesh Talwar killed their daughter.
He said earlier that during investigation no outsider's entry was found possible inside the house and all the three helps had nothing to do with the murder of the teenaged girl.
Aarushi, 14, was found murdered at her parents' Noida residence May 16, 2008. The body of Hemraj, a domestic help of the Talwars, was found the next day on the terrace of the house.
