I just have no understanding of greek life, or college party life, so I would be 100% guessing. I'm 60 and I was floored that there was a party going on when none of the residents was even there, and another poster thought it was hilarious that anyone even thought that was strange. Clearly, I am not the right demographic to draw conclusions on that situation. LOL
I will say that anywhere you have a mix of people and personalities, I think there is the potential for a conflict serious enough to end in murder. I would be shocked to learn that it was someone from the neighborhood pissed off about the parties. I would have expected more escalation between calling the police to complain about noise and murder. Maybe there has been more escalation and we just don't know it. But I would also think calling the police repeatedly about the noise and then killing them is a great way to make yourself an early suspect.
I went to college but worked to pay my way, so I was not part of the Greek scene and did not live in a Party house. Our house did have several female roommates, and sometimes their guys would kinda move in. It is easier for a guy to move into a house of girls, than it is for a girl to stay over with her guy in his dorm or frat house.
My experience was in the late 80’s-early 90’s so things have likely changed. The culture of university life is not a single thing. In my experience teaching the single most factor that makes the difference is family culture and expectations.
Serious students work and take school seriously- some are the first in their family to go, some have tough majors and are headed to grad school, they want to make their family proud.
Party students extend their high school playing years, no responsibilities, no job, no bills, just don’t piss mom and dad off so the $ stops.
And every kind between, older students, international students, premeds, artsy, business, Greeks, athletes, geeks, none of those words alone define A type.
These girls seemed to balance work, school, and play.
It is interesting that grad students, and others who were not in school live near so many partying students. Those serious about school who work and have tough majors do not live where parties are common, only to get mad when students party. That seems odd To me.
