No finger prints were found in that blood...generally smeared blood looks different...this blood was the torrent that flew(when the jugular vein is cut, the torrent can fly several feet) when the throat was cut, that had been confirmed by the NOIDA police itself...don't underestimate the police findings..even they are paid to do a job!!
FYI, this door opened from the inside, so the door was wide open when she was murdered...
