1. krishna and rajkumar are not nepalies ... if rajkumar killed arushi after attempting to rape her, let's not blame nepali servants.
2. not unless they were making noise while having drinks
3. often one scream isn't enough to wake someone up from deep sleep ... maybe the assailant thought that arushi would surrender, or consent, but when she didn't he muffled her sceam and then had to kill her
4. maybe she wasn't dead after the heavy blow, just driven unconscious and then she died ... slitting will result in blood outflow as long as the heart is pumping ... also some blood will ooze out of recently dead person when a blood vessel is cut ... it may have stained assialant's hand who left the blood marks on the door.
No offense .... just doing timepass to screw your theory.
