Prime suspect untill yesterday was Rajesh Talwar why not do narcoanalysis on him and if he is your prime suspect Mrs Talwar becomes an accomplice she has not even been arrested. See the double standards, all servants picked up without charge and subjected all unscientific tests but the rich get away. Its not proved they are innocent neither its proved they are guilty. So wait for the investigations to complete although the way the CBI is progressing I don't think they will catch the real culprit.
