Landlord Illegally Evicted Me With No Notice. Left My Property Outside In The Rain. Won't Refund Me.

For some background, I have been staying at this little cottage behind the home of an old lady in Louisiana for approximately a month while I'm out on business. She had her listing on Craigslist, but curiously not on airbnb or any similar service. I arrived on April 30. I paid for two months rent in cash, and have a signed receipt for each transaction: $2,236 for May, and $1,685 for June. She and I had an issue in the latter part of May, where she wanted to enter the building for professional cleaning, and I asked if she could reschedule because I only got a few hours sleep due to my insane work schedule. Note that I never denied her entry. She never actually visited the property on that date; I simply texted her asking if she can reschedule. This was a huge problem for her, but she did agree to reschedule. She was very clear that she very, very much did not like that, however, when she told me she would bring the police over to force entry on the rescheduled date if I won't let her in.

She later sent me a seemingly innocent text message asking me what my work schedule was like on Saturday and Sunday, since she wanted someone to come for some sort of maintenance on a generator. She has surveillance cameras, so she knows that I work pretty much all day, sometimes not even returning to the cottage on weekends. I explained as much to her.

Just a few hours ago, while I was out on work, I got a text from my landlord with absolutely no notice beforehand telling me that her cottage is now closed, I'm not welcome back, she changed the locks, and that she left my stuff outside in the intense rain. I drove to the police station and explained the situation, and the police told me it's a civil matter so they can do absolutely nothing about it. The police officer escorted me to her home at which point I collected most of my property (except my perishable groceries, which I had no place to safely keep) and filmed their condition. There was a piece of paper that said, "I consider you dangerous. Do not contact me or come to my property," affixed to my things which were sitting outside in the rain. There was also a receipt from her Internet company claiming she went over on data usage and it cost her $100, which she alleges I now owe her. She and I never discussed any sort of data limit on Internet usage, and nowhere on the receipt or the Craigslist ad mentions any data usage limit. The police officer had a conversation with her inside her home, and according to him, she alleges I have a past conviction that I got out of on a technicality, which is why she feels unsafe. I have absolutely no criminal record whatsoever, I don't drink, I don't smoke, and I don't do drugs.

I'm now staying in a hotel room that I had to reserve at last minute notice, and that's where I am writing this post from. From my understanding, this is in no way legal, but the police refuse to do anything. What's the best way to move forward with this? What civil measures can I take? What can I realistically expect to get out of a civil suit? I've never been involved in the legal system before, so I really don't know where to even start.
