Ghaziabad, Oct 24 (IANS): In the Aarushi-Hemraj double murder case, defence lawyers Thursday sought to refute the CBI theory that the dentist couple Rajesh and Nupur Talwar killed their daughter and their servant following sudden provocation.

Defence lawyer Satyketu Singh submitted that the prosecution theory that the murders were committed by Aarushi's parents, Rajesh and Nupur Talwar, is based on Gandhi Nagar-based CFSL scientist Mahendra Singh Dahiya's statement and is full of holes.

The defence said that first, Dahiya never visited the crime spot. He made the statement on the basis of photographs and the statements of doctors Sunil Dohre and Naresh Raj submitted to him.

The two doctors, in five statements during investigation, never mentioned that Hemraj's blood was found on Aarushi's pillow. But, they said the same in the sixth statement which is in contradiction with B.K. Mahapatra's report which said no blood or other DNA evidence of Hemraj was found in Aarushi's room.

Second, Dohre initially mentioned no abnormality was found in the vaginal part of the deceased but in his sixth statement, he said vagina was dilated. Why did Dohre not mention his finding in the post-mortem report or earlier statements? Such fabrications are in contradiction within its own claims, said defence lawyer Manoj Shishodia.

The lawyers said that most importantly, doctor J.L. Kaul himself mentioned in his closure report that no evidence of blood or DNA was found in Aarushi's room. So, the CBI saying that Talwar parents killed their daughter is not sustainable.

The defence presented arguments from 2 p.m. to 4 p.m. The CBI judge adjourned the court to Oct 25 to record defence arguments.

Aarushi, 14, was found murdered at her parents' Noida residence May 16, 2008. Next day, Hemraj's body was found on the house terrace.
