Housemate from hell, need help!

[wishinhopin]

Ok so here's the situation. Liz and I moved into a house with our best guy friend, Adrian. For a good year before moving in together, Adrian was at our house every day, and often every night. We were all super tight and got along really well. So we felt like things would work alright with all of us living together. This was definitely not the case. Adrian started being vindictive, disrespectful, inconsiderate, disgustingly messy, and in general just an ass. He didn't feel that paying rent on time was particularly important, nor did he make an effort to clean or respect basic house rules.
Examples of his behavior:
-Bringing over 10 friends to our small townhouse, and all of their infants and toddlers, even when I repeatedly asked him to respect that I had school/work/finals early in the morning. I don't have kids because I don't have the time or energy to deal with them right now- and this includes being woken up a good 5 or 6 times each night by some screaming baby who is confused as to where they are, and where their mommy was.
-Speaking of their mommies...Adrian et al also had no problem smoking massive amounts of pot around the kids. Don't get me wrong, I smoke myself, but I don't consider it appropriate to do so around babies! This even continued after one of his friends, Marcy, got busted by CPS for doing drugs around her baby at her house. So what did she do? Just brought the drugs and the baby to our house. Not cool.
-We lived in a gated community, with many families and old people. It wasn't a college living place at all. Furthermore, we shared walls with townhouses on either side, and could hear many things crystal clear. This still didn't stop Adrian from doing drugs with the windows and shades open so that anyone walking by could see, blasting offensive music (I love Lil Kim and 50 cent just as much as anyone else, but I don't think that our toddler neighbors needed to hear what they have to say), going outside at 3 am and screaming (direct quote here): "Jesus Christ, that c--t slut whore couldn't handle another bong rip!"
-Etc, etc etc.

Because of his behavior, our landlords aren't particularly happy with us. So, to cover our own asses more than anything else, Liz and I decided to move out. He still owes $300 for rent this past month, which he now claims to know nothing about. He also owes Liz and I considerable sums of money, and that isn't even including what he should owe us for eating all of our food, stealing our movies and cds, and ruining and/or stealing several pieces of furniture. The PG&E bill is in his name, and he is still living at the house. Liz and I are completely moved out now, and so we weren't too concerned with giving him money to pay this bill for electricity that we don't even need. So, we cleaned the whole house, top to bottom, while we still had electricity. We also asked Adrian not to dirty areas we had already cleaned, and went so far as to lock the doors of any area we could.

When we returned yesterday to check the mail, we wanted to also check and make sure the house was still clean, since our landlord was planning on going to the house that morning. When we got there, we found the place a complete mess. There were people all over the living room, alcohol and pot on the counter, the bong on the living room floor with ash spilled on the carpet that I had to steam vaccum to get rid of the previous stains he left there, and he had gone into all the locked rooms- including our bedrooms- and gotten them dirty.

Obviously, we are frustrated. So we called the landlord immediately and explained what we saw, and he showed up and saw the same. He understands that we're in a shitty position, but he also needs to have the home clean before new tenants arrive. So basically I think we're shit out of luck, but I was hoping someone had some advice for us.

Oh, other detail. Liz and I tried to be very responsible during all d this. Since his phone was turned off, and he refused to speak to us in person, we had to resort to leaving letters for him. We have copies of all correspondance between us- for example, when Liz wrote a letter politely detailing the money he owed her, and what his options were, his handwritten response was simply, "Go f--k yourself b--ch". We also took photos of everything we cleaned, as well as all the mess that he left.

So what do we do now? He can stay in the home until the 1st, and there isn't anymore electricity in the house. So there isn't going to be anything we can do about the carpet anymore, and I know it's been stained in the past few days. We don't want to have to go back and try to clean again, but we need this money really bad. Does anyone have any advice, or knowledge of any options we might have? I guess it helped just to write it all out, but I'm desperate here- it's so frustrating! I feel like Liz and I are being punished for being the adults in this situation, and I hate it!
