There are many commenting that the actions or behaviors of these kids seems 'strange' to them and speculating on dark scenarios based on their unfamiliarity with those actions or behaviors. In my experience and in the experiences of many other posters, all these kids were behaving exactly as US college students do on a Saturday night in 2022. There was nothing nefarious or odd. The four victims and their roommates were out on a Saturday night and came home right about the time bars were closing - 1:45. They were out on the town for hours according to the times stated by LE, bar crawling, drinking, getting food post-bar crawl so you can soak up the alcohol you drank, catching a ride home with someone, going to frat parties or dances; roommates trying to sleep and maybe using earbuds to block out noisy roomies, locking their doors so someone visiting doesn't barge in and wake them up, sleeping in late after a night out, leaving a door open for someone without a key; drunk-dialing an ex over and over. All of the above are normal! They were college kids on a Saturday night. The end of that night took a terrible and dark turn. That's what IS abnormal. Up until they were killed, everything was normal. moo
