How can CBI believe the story narrated by Rajkumar. Dr Talwar does not live in a haveli so that he can not hear what is happening in one part of it. Its an apartment where small noise can easily be heard. When they entered Arushi;s room she must have shouted at least once before being killed.Again if Hemraj threatened them thet he will expose them he could have shouted also while being dragged to the terrace and any one will will di if the person is being drageed for being killed...Story is something different which CBI wil have to unearth.Lets see.
