Krishna says that Rajkumar had the beer.But there was a whiskey bottle in the room with three glasses.
The khukri was requested by Hemaraj and that was a day before the murder. According to Krishna he indeed carried the Khukri and gave it to Hemaraj. It is possible in three bed room house with servant quarters and AC rooms ,the sound may not be heard perticularly if you have locked the doors and also deep in sleep at night 2 am to 4 am. Krishna seems to be a hard criminal and hard to crack. But he started singing now and reveal more. The important aspect of the case was to find out the motive. If Aurishi's body was preserved it could have been very easy to find out more clues for the CBI. Earlier reports on this murder mystery suggested semen marks on Aurish cloths.
But now the case is not becoming complex at least. It has started to reveal slowly but surely.
