Cool out guys before giving remarks lets look at what CBIs are telling. They said Hemraj, Krishna and Rajkumar was drinking. Krishna want to teach Talwar a lesson and then Rajkumar proceeds to Rape her. Now think for a second here.
If they were in Drunken state why they want to destroy the mobiles of both Arushis and HEmrajs????
If a person is in drunken state attains the "kama" he will not be in a position to clean up the act after killing and neither will he be in a state of mind of destroying the mobiles what say guys?? won't he leave some clues??
