That's freaky. Makes you wonder if he didn't suspect them himself, huh? I feel sorry that Trumbower got treisked like that. He'll never live it down. 
Here is my funny story:
I saw a post on here months ago by a breeder talking about his ruthveni hatchlings. I emailed him and asked where he got them from. I wanted to verify them, find out they were pure, and possibly get some babies if they were from a pure line I didn't already have. The breeder's reply was that he did NOT reveal his sources. I thanked him and informed him that I couldn't acquire ruthveni that I couldn't verify myself - even though I trusted his judgement. He seemed to have gotten upset, and then he told me that he wouldn't have sold to me anyway because I wasn't part of his clique. About 2 months later, I find out that Daryl and I owned the adults that produced the ones he now owns....lol.
OK, so they can verify now be traced good enough for me, but if I would have purchased them, I might have been inbreeding them backl to one of their parents without even knowing it. That doesn't sound good, does it? This is another reason why The Gint was right when he said to know your breeder, your breeder's breeder, and even his breeder.
No harm down, I didn't get mad because he didn't give me further info (but I got upset because I was hopeful that it was a new bloodline that I could maybe verify), and everything turned out OK in the end.
