1) Krishna is a Nepali......Rajkumar is a half nepali half UP guy....
2)They are humans and not limp rags for them to move around silently or glide in the air like a butterfly.......
3)One scream is enough to wake you up from a deep slumber....esp. if the scream(even if muffled one)is in the same house barely 4 feet away.......have seen the layout and followed the mock drill on aajTak...
4)Going as per media reporting of forensics investigation...she died 20 minutes before the throat was slit....in which case, the blood would barely ooze out...a dead heart does not pump blood vigorously...LOL!!
Hey no offence meant...just some tp to dismantle your theory...
