TLDR: The real property owner contacted the town to block the building permit, and then contacted the other people involved in the sale, the documents provided by the scam artist were obviously foraged, but the sale still went through and construction started.
The other major difference between this one and the other link I posted is that the owner was very likely going to build a home on the property when they retired; unlike the other link that I posted where the property was most likely an investment and going to be sold.
