Possible Domestic Violence from my Upstairs Neighbors

WARNING, I WILL BE TALKING ABOUT DOMESTIC VIOLENCE

Hello. I currently live in a decent quadplex (with lots of other look-alike quadplexes near me) and have been here for about a year. I live on the bottom floor and recently I got new upstairs neighbors. They were your typical loud, don't care about you, kind of neighbors. They walk loud, seemingly come home and instantly rearrange their entire house, loud music, parties that last from 9:30 to 12 with crappy loud EDM music.

However, about a month in I heard them having a screaming match at 1 am where a man and woman would be talking and you could hear them scream, "SHUT THE FUCK UP.. NO YOU SHUT THE FUCK UP. GET THE FUCK OUT. NO YOU GET THE FUCK OUT."

More recently I had to call the cops on the the other day. The reason being that me and my roommate heard a child screaming and running down the stairs with a man following her down. Then we heard a women come out saying that he had hit her child and that he also put his hands on her throat. And then you could hear them talk a bit and she responded to whatever he said with "Bullshit you fucking psycho"

I ended up recording this event. However when I called the cops I overhead the man open the door and I heard him roughly through our doorbell cam about possibly her being the abuser?

Tonight I called the cops again because I heard really loud thumping noises and both me and my roommate heard a woman weeping and sobbing and a man yelling really loud. And occasionally we would hear a really loud thumping and I remember hearing the thumping going throughout the entire house. It sounded like he was throwing things and scaring her and even chasing her around. When we called the cops this time, around 6 cops showed up and this time they didn't spend a lot of time talking to them and actually asked us a few questions. They told us that they had gone upstairs and a man had answered and said they were having a really loud poker party night and that they had checked and there was no woman. The neighbor also said that it might've been the other neighbor but I told them I know my neighbors and they're really quiet.

I recorded part of the incident but forgot to show the cops this. And initially, I thought me and my roommates were mishearing things and it felt like the gaslighting from our neighbor was really working. We were beginning to believe that we were just overhearing a really loud poker game night. Listening back on the audio you can tell that it was a woman weeping and sobbing while a man yelled at her with the video cutting off when you can hear a really loud scream and thump.

Not sure what to do besides calling the cops again. Some of my roommates closest people have told her she needs to get our local woman's and children's alliance to help get her out. I've also been emailing my property management about the situation and they are on my side for calling the cops and to keep calling them whenever something like this happens again.

However, I'm also a bit concerned for my safety as I've been updating this situation with some of the people in my life and they tell me abusers hate having the cops called on them and sometimes they'll try to go after the caller, or continue to abuse their partner even worse.

Any advice on this situation would be really nice.

TLDR; Called the cops on my upstairs neighbors twice for overhearing really concerning things that I strongly feel are related to domestic violence. Cops haven't been able to do anything yet and Im getting worried about my own safety and our neighbors.
