How to sent to the collection for non payment of rent?

[Mahmudul Shoikot]

I posted last time also about my tenant who was not paying rent and asking if  I could send it to the collection agency. I asked her to vacant my house before I file for eviction. She emptied my house with an outstanding rent of roughly 5k.  I don't live in Texas, but I went last month to check my property and found some of her mail where there were other outstanding bills and even an arrest warrant ( for not paying tickets I guess). So, I see a very slim chance of getting my money back. 
How can I get that money back?
I want to send it to the collection agency if that's possible. I tried to look for it and contacted a few but didn't get any response back. I would appreciate it if I could get any suggestions.

Thank you all for your help.
