It is surprising why Dr. Talwar is not co-operating with the police & CBI. Does he not want his daughter's murderers to be brought to justice. Why did Dr. Talwar ask his servants to dry the matress on neighbour's terrace & not his own? Who took the call of the milkman on Hemraj's mobile? Why was the Talwars' behaviour very strange with the maid at 6 am. Why did the mistress leave Noida just one day before the crime? Parents show no grief at their one & only child being murdered. Mother & mistress should be subjected to lie detection test. Give CBI time & lets not criticise them. I'm sure that they will crack this case beyond least doubt. The culprits MUST be booked at all cost. Best of luck to CBI.
