Just get the son out, keep her security deposit - do it right according to the law, and if you want to spend money on a losing small claims court (as far as being likely to collect without spending more money on a process server and then still not collecting from her), then that's your choice.I'd probably not bother with suing her, but I suggest you study how to screen tenants better. 

Obama also asked these leaders to base their cloud-servers in places receiving renewable energy.

The server has received no answer on their attempts.

Do you know how to find him, so he can be served by a process server? 

That could be done with tracking of some kind, or if the process server had a witness with them, maybe. 

Joe's lease has provisions against this, so I properly serve him a "10 day notice to cure" using a process server ($$).

Talk to an attorney about timing and have the tenant served by a sheriff or process server. 

Schlage is usually doing maintenance on the servers which can cause the locks to become disconnected.Another thing you could do is put in 5 or so emergency codes for guests just in case.

If you don't know where they are, you might want to pay a process server to find them.  

If you are provided with great service and a great meal but only make your servers/cooks job harder by being ridiculously nitpicky, rude, and never showing gratitude no one is going to want to serve you.
