A CBI team under Arun Kumar had concluded that murders were allegedly committed by Krishna Thadarai- help at Talwar's clinic, his friend Rajkumar—a domestic servant with Praful and Anita Durrani who were Talwars' friends, and Vijay Mandal, driver of Talwars' neighbour.
These findings were trashed by the then CBI Director Ashwani Kumar who found holes in the theory by underlining the gaps in the arguments given by Arun Kumar.
Lal outrightly rejected the deposition of CBI SSP Vijay Kumar, who was part of the first team under Arun Kumar, saying he had “wrongly deposed” on the basis of disclosure statement made by Krishna that the ‘kukri' was recovered from his room.
He said that in the exhibit shown by CBI it has no where been written that on the basis of the disclosure statement the recovery of ‘kukri' was made on June 14, 2008.
During the trial, the defence had tried to bring forward the role of the three servants saying the lie detector test, brain mapping test and narco analyses test at FSL, Banglore, and the tests indicated Krishna had revealed crucial information leading to the double murders and his complicity is found.
