Vetter was just a girl that he dated while he worked in the area. They were never married or anything. Just kinda threw it out there in case he read it or someone that knew her and him when they were together read it. This is really like finding a needle in a haystack. I have no idea where to go from here. I do not think he is deceased (but not 100% sure). His daughter would be between the ages of 38-47. Unknown if he had kids after 1975. I suppose maybe its time to just give up.
