"Spending a few days dead for tax purposes."

I am trying to get in touch with the following:

Person 1 - far too tied up emptying and decorating an attic.

Person 2 - missing presumed ill or stressed out.

Person 3 - missing presumed ill, stressed out or asleep.

Person 4 - generally too stressed out to get in touch with me.

Person 5 - generally too busy to get in touch with me.
