He lives with my mom and his wife of 50 years. My brother and sister flew them out to Las Vegas last October to celebrate their 50th.
My brother has a summer home on the same block and my sister lives less than a mile away with her 2 daughters.
No crawl space and the attic was searched.
Prayers for your handsome dad.
There was a case around here with some missing children -- everyone looked high and low for days. Eventually they were discovered in the trunk of the family car that was sitting right there the whole time. It was thought that they fell in and then couldn't get out. Please check to see if he might have fallen in or been pushed by bad kids passing by.
