I would like to see the room exit video. POI appears to be wearing a snow type suit on way up. So after stabbing, it wouls be easy for POI to peel off blood evidence snow suit put in bag, briefcase, etc. and exit hotel looking like a much thinner version of whatever gender it is. Heck, we would not know what to look for except height, gait, non caucasian. Perhaps this is why exit videos are not shown as many guests exiting 4rth floor to? ? another floor? and ultimately outside is obviously being reviewed.
