As a rural dog warden, I too have come across these predicaments. As far as the incarcerated goes, I have called the jail and asked them to get me information on who I can contact on the owner's behalf to take over the care of the animals. Most are very accommodating to me, as everyone loves animals, and get me the information pretty quickly. They have even gone and gotten the inmate, so I get information straight from the owner. Same with Rehab, there I usually do not talk to the owner, but the staff will help to get me the information I need to see to the care of the animals. Nursing home, Hospice, DOA's, etc. I do my best to try to find a close family member to make sure there is no one wanting to step up and take responsibility of the dogs. If no contact can be made after 14 days, we assume custody of the dog. In my state, a dog with tags we hold for 14 days, a stray is 3 day hold.
I hope this helps you in some way. Each case seems to be just a bit different that it takes on its own issues. Paperwork in all cases is a must for me. I want address and phone number's to anyone I have spoken too. I have used FB many times message people to see if they can help me. It has worked for me.
Good luck
