30 day notice for noise, tenant moved, now what?

[Dan O'Neill]

I served a 30 day notice to unit due to on-going obnoxious noise which was disturbing others. We’re talking snowmobiles at 2am, rocking until 5am type noise. I wanted them out. They didn’t drag it out, they cleaned the unit well and moved out within the 30 days. Do I need to do anything here to wrap things up with them? They cleaned it well enough that I was going to refund a portion of the sec. deposit but I found out the tenant is now sitting in the county jail for something. What the heck do I do with the sec. dep. in that case?
