Roommates making threats, not sure what to do

Sooo idk where to start, but we have some horrible roommates. Here we go. My wife and I moved into a place with a friend. About halfway through the first month, one of our old roommates (Josh) came to stay for the weekend. When he showed up I looked at him funny cause he had a LOT of stuff with him so he literally said "don't worry I'm not moving in. Well he stayed here for two months before we finally said "hey get a job and contribute", which he did. By the way, it is only my wife and I on the lease or bills and it has stayed that way. Our initial roommate ended up moving out and we moved in some old friends (Heather and Layton). We gave them all three simple rules: don't lie, no drugs (besides cannabis), and keep it clean. Within the first week of them living here they were all three smoking opium, lying about it, and their rooms were trashed. About a month in we decided to give them a thirty day notice to leave, which luckily Josh didn't care about and left that day. Well this caused a bunch of bullshit and they ended up breaking our washer machine, our fridge and our Faucet, which they are not going to pay for. They are now saying things on Facebook like "oh we have people going after them they gonna get their asses BEAT" and "they'll never get a job in this town again I'll make sure of it" And I have several messages from Josh saying he's going to beat my ass personally. Well the thirty days is almost up and they hadn't packed a thing and we could literally hear them saying "oh they're gonna die" so we started to just take their shit and packing it up and putting it in front of their door, and Layton busts out getting in my wife's face, then turns on me so my wife runs up and tells him to get out of my face and then shoves him when he didn't. Well he fell in the most dramatic way possible and they both ran in their room and called the cops telling them that we assaulted them and we sell weed. Immediately after getting off the phone the ass runs into our room filming us yelling "BUSTED BUSTED YOURE SO FUCKED". Well funnily enough, we used to sell bud, but don't anymore and haven't for a while. The cop showed up, spoke to my wife for 2 minutes, then apologized to us for having shitty roommates and left. It's been quiet since then, except for more and more people chiming in on their Facebook plotting getting people to hurt us, slandering our name, lying about us and much more. We have screenshots of most of it. I guess to put this into some kind of perspective, Josh is a 38 year old felon who has multiple violent crimes on his record, Layton is a 26 year old deadhead who smokes and snorts whatever he can get his hands on, and Heather is a 17 year old pathological liar druggy who literally used my best friends funeral as an excuse to go cheat on Layton. I'm 23 and my wife is 19. What do we do at this point? We don't feel safe in our house. Edit: Heather is 19, not 17. My wife corrected me. We live in Oklahoma, Cleveland County
