Property left behind by an evicted tenants guest.

[Leinaala Fernandez]

I have a 2 bdrm rental that I rented for 1400 and received a 1000 deposit. Mo to mo lease.  Gave tenant 90 day notice to vacate as a courtesy because only 45 days required by law but I know it's hard to find rentals these days. As soon as my tenant received the notice they stopped paying rent for May and then in June. On July 6, going on the 3rd month without rent I gave them a 5 day pay or quit notice. They didn't respond and  they never tried to call me to tell me what's going on. Many attempts to call their cell but no answer. So I caught them at home one day and told them to use the May and June rent for their deposit and first months rent on another place but they needed to be out by July 11 because I can't go 3 months without rent. July 11 came and they still were there and the garage was still full of all their things. Long story short is I finally got them to leave July 17 but my tenant had illegally moved in his  friends daughter and 8 year old son who was never put on our agreement. When they left on July 17 they said she would be back to following day for her furniture and boxes that filled up the entire garage. Well they haven't been back yet and the house was left very filthy as if it were never cleaned for 8 years that he lived there. Dirt and mold covering the walls and blinds in every room. So, my question is she was never put on the lease so what can I do about all her things left here? They left me no forwarding address or contact number. He's retired and she is not employed so I have no way of getting a hold of them. Thank you
