I stated this on another post, another viewpoint is it’s college life, how many unannounced guest came and went from that house? Another poster commented that if it was a Covid type mask (The description was a mask that covered his mouth and nose so sounds like a Covid mask not a ski mask) that in itself is not alarming or suggestive of criminal activity. Yes, she was startled by the presence of an unexpected person but again is that the first time that that has happened? Did her hearing, it’s OK I’m here to help, make her think the situation was being handled and her intervention was not necessary? She thought one of the roommates was playing with the dog, again that doesn’t suggest foul play. doorDash was delivered moments before the murders putting the meal delivery in the 3:45 AM range, normal middle of the night activity for this house so not unusual? I know it’s not common for delivery drivers to come in the house but again college life, college kids, did she just think it was a delivery person or a friend of one of the roommates who made the delivery, or the roommates brought someone home? I don’t think you can view her from the same lens/thought pattern as an adult who is always checking on children or others if hearing any type of noise etc. I don’t think her mind would necessarily go to the thought that possible harm was being done to her roommates.
