In the video Rex did with the Bonjour Realty guy, he made mention that when he went out on his own, his first "paying client" during the 90's recession was a man named Robert Mayer. They met when they were standing in line at the Queens Building Dept.
He pronounced Mayer in the video as one would say Oscar Mayer...(like "My"er)
There was a Robert Mayer who suspiciously went missing in 2013 from Dix Hills. He was an electrician, so it makes sense he could have been there pulling permits in the 90's. He was roughly about the same age as Rex, I think maybe 2-3 years younger. His vehicle was found abandoned at at train station that was beside a nature preserve IIRC.
Just thinking out loud, wondering if it potentially was the same man, or if Robert Mayer's name was pronounced more like "May"er, not "My"er. Not sure if any locals on here who may be familiar with that family and how they pronounced their name?
