Concerning noise — what else can I even do?

A week into my new place—which I picked because it was so quiet. Around 1 am, I hear loud thudding and banging noises. It quite literally sounds like someone is moving furniture and banging it into the walls….except against the ceiling. I’m on the top floor and all the noises are coming from below. I would’ve just dealt with it if not for the screaming. Arguing, cursing, at one point one of the couple members was screaming for a full minute just at the top of her lungs while their partner told them loudly to shut up. The banging also continued loudly enough for me to be concerned that there was violence going on.

I called the non emergency line. They asked some questions. After an hour, they called back to ask how the noise was. I told them truthfully it had quieted down, so I’m not sure they sent anyone out. An hour later, at 3 am, they had another screaming and banging match. This continued every two hours until 7 am when I got up for work.

I reported all this to the office who told me to contact the courtesy officer on site in addition to police. The fighting and noises quieted down for a few days, then started again last night, the night before my first day at my new job. Of course.

Things were worse tonight—I actively clearly heard the girl say she was going to kill herself and I recorded it. I also ran into a neighbor who has heard the noises as well. Now both the courtesy officer and police have visited the offending apartment, but both said they didn’t answer the door so there’s nothing they can do. I googled a welfare check and it does say you can call one for someone you don’t know if you have concerns about them harming themselves. I told the police about what I heard and offered the recording as well. I was surprised that wasn’t enough for them to at least enter the apartment.

It’s quieted down, for now…but I have work in less than 6 hours and fried nerves thanks to all this. It’s really frustrating and I don’t know what else to do. Im starting to become anxious about the noise and the concerning things being said. I don’t know if it’s a domestic violence situation or just a toxic couple. I just want to be able to sleep before I go to a job where I’m responsible for other people’s lives.
