I think what krishna had told during the test may be not 100% correct but if we think, we all are guessing that the murder took place in the Aarushi room, but it can be also happened that may be aarushi gone to Hamraj place for any reason and there all this things happened and after that they might be place her body on her room. That’s why may be her parents did not have any clue of sound or noise.
