My question involves civil rights in the State of: Colorado
Let me start out with introducing myself, im a 17 year old girl in Denver, Colorado
My mom has had a very abusive boyfriend over the past 10 years. She left my dad, me, and my younger brother and sister for him.
About 4 years ago, she brought her boyfriend and his 2 kids over to my dads house, and having the kind heart he has, he didnt kick them out right away because of the kids.
Now we don't even have a choice. We've tried kickong him out, but he refuses to leave. He has paid maybe loke 3 bills in total since hes been here, he'll refuse to help out.
The cops have been over before, but either he runs, or he lies through his teeth to them, so they havent ever actually done anything about it.
This man, Julio Ricardo Gonzalez, goes by Rick, he is really abusive. If you do something he doesnt like, or even if you log into the wifi, he will go off and explode at you, cussing you out. He plays video games all day, so if he gets any lag in the game, he blames me and explodes at me for being on wifi, even though im a college student and have homework to get done.
Not only does he yell contantly, but if its one of his kids, he resorts straight to beating them. His older daughter calles social services on him beating his younger daughter, but because the younger daughter is terrified of him, she lied to the police for him when they arrived. He has also beaten my mom before too, and always threatens to beat us too (my dads children). Hes even held an ax up to my face telling me not to go any further
He lives in the basement, and my room is down there. He has beaten at my door so many times being mad at me, that the door wont even close correctly, and he knows how to get into it when its locked. For a while, he even stole my room key.
Another factor, is that he has sexual feelings for me, he has told me his fantasies before, and they all scare me. He touches my upper leg and butt whenever hes around me
I havent slept in my room in months now, I've been sleeping on the couch to stay away from him. He has completely taken over my room.
Initially, i was waiting until i was 18 and then gonna move out, but after a recent event, he needs to get out ASAP.
My mom tried committing suicide 2 days ago to get away from him, she felt that was her only option to do so.
I would like to conduct a welfare check on my house to get this man out. If i call the cops directly, hes run, or try to get a restraining order on me and my family, which could potentially kick us from our own home.
I need advice as to how i should go about this. My dad doesnt want the cops called either, he said hed take care of it, but hes been saying that for the past 4 years now.
I just wanted to see what people would say i should do, because i dont know short of anonymously calling the cops.
