Tenant left without notice-Wisconsin

[Karl Huth]

Need some advise. I have a tenant that I believe no longer lives at the property. She was behind on rent and facing eviction. I have tried to get a hold of her through her old phone number and via Facebook but have not heard from her in a week. I got ahold of her cousin who said she has moved. What steps do I need to take to properly end the lease and evict her so I can clean the place up and re-rent it? I posted the 5 day notice on 12/2/17.
