Dr Rani Bhatia, a private practitioner who studies human behvaiour, particularly stress related cases, found it impossible to support the theory advanced by the Noida police in the murders of 14 year old Aarushi Talwar and her family servant Hemraj.

Dr Rajesh Talwar, Aarushi's father was arrested for both the murders. 

The arrests were made on the basis of an SMS sent by Aarushi to her friend, in which she spoke of the extra-martial affairs of her parents Rajesh and Nupur with another woman doctor.

"Sexual behaviour in the society is changing very fast while some are able to accept it and some are not. Human behaviour is not the same at all the places. Maybe Aarushi was not able to cope with the behaviour of her parents. One of the reasons of Aarushi's hatred could be that people she knew, were also aware of the extra marital affairs. Children would like to see their parents as role models otherwise they would not be able to wield any moral authority over the children. Over exposure to the electronic media has had an adverse impact on the children as well and this needs to be studied," Bhatia said.

Last year we had a similar case in Mumbai where friendship with boys started on harmless note and later that boy was murdered," Bhatia said.

Bhatia is worried about the impact of such incidents on children in particular as the Indian electronic media is growing at a rapid pace.
