Death of tenant with no apparent heirs

[Greg Elkins]

I am interested in any experiences dealing with the death of a tenant with no heirs.  My tenant passed away and was not found for apparently several weeks, so the smell in the house is unpleasant.  

Interested in a few things:

1. How long do I have to keep their belongings in storage if at all?  

2. Cleanup process and how to best get the smell out of the house?

Thanks for any advice!
