The prosecution told the court that the doctors who had visited the Talwar residence the next morning of the murder had found blood stains on the lock of the door leading to the terrace, the railing and on the stairs.
The blood stains trailing towards the terrace supported the CBI theory that the Talwars had dragged Hemraj's dead body in a sheet to the terrace.
The additional sessions judge Shyam Lal has fixed the next hearing date as October 17.
