Too bad. I was hoping one of those would show the house had been transferred to someone else. There are a couple of obits on legacy.com for Stayers in Arizona that you might try if you haven't already. If he's not shown as a survivor that might be a clue.
Most Phoenix deaths are published in the Republic and I think all Republic obits are transferred to legacy but maybe not permanently.
I suppose someone could call the phone number to inquire though I understand why that might not be desirable.
