Maybe I’m strange here but I can completely understand why she didn’t ring the police or go out to have a look.
The whole murder apparently only took 20 minutes and there were no screams reported which would definitely have been included in the affidavit.
We don’t actually know what she saw, only that she saw him leave and had his face covered. She doesn’t say she saw a knife in his hand or blood. She said she opened her door to some noises that according to her report, in my personal opinion, are perfectly normal noises for a college party house, especially after a night out of drinking and somebody coming home with their boyfriend and ordering food at 4am. I’d imagine that’s a fairly regular occurrence. My mind would not be jumping straight to “my roommates are being murdered”. She probably locked the door after being a bit freaked out that some random was in the house and thought “I’ll ask them about it in the morning” then went to sleep probably about 5am and woke at like midday which is arguably a normal amount of time to sleep for if you’re up at that hour.
I don’t call the police everytime I hear a noise that makes my brain go “well that’s a bit weird”?
Not to mention, the brain’s ability to convince you nothing is wrong. So many times I’ve heard
tit (especially at uni, it’s the Wild West out there) and gone “yeah it’s probably nothing”. The amount of times random people came into my uni housing at all hours, honestly. One guy threw up and tried to hoover it up and broke it no lies
like i said, maybe I’m weird but having been a student, it is understandable to me
