Murder was preplanned by smart ppl thasty cops dint find any evidence at crime location.Let assume for sake of argument that Krishna killed Arushi coz he had a bad eye on her..And CBI told that Krishna & Hemraj were drunk that night..Usually if a person is drunk and had bad eye on some girl he tries to Rape her first and kill her but here investigation said there was no protest from Arushi..She was killed immediately (So i am not sure abt new story from CBI) and if she was killed then Hemraj would have shouted and parents would have come out of there room. Again for sake of argument lets say hemraj dint shout and he was also killed..Again krishna is under influence of alcohol & no person can clean/clear evidence from site this wisely that cops cant find any evidence nor CBI, all CBI story is based on assumptions. Even now CBI came with a new story that they were not at home that night.Any parents whose only child got killed will tell cops everything happened that night they wont hide anything..still its not clear where they went out and why.So initially cops and CBI said that Talwars statements are not matching..now the story is completely twisted. CBI is not looking at Talwars..all the tests were done on Krishna but not on Talwar..I hope vistim get Justice
