Karen claimed to be a dentist, but the only thing I could find was a linked in profile as a dental hygienist. I somehow doubt an actual dentist would up and move 4 hours away with some Tinder guy.
Also: Saint Cloud, MN! It's not a big city, and when I checked out Logan's facebook page, we had two mutual friends. He definitely likes the pot, which is why he knew where he was on 4/20, even though obviously Judge Judy didn't (and Byrd didn't tell her the reference). I do believe he got his dog high, but I also believe he probably takes good care of her.
Also: The lovely Madison, who was there with him, was just a few months clean from "hard drugs" when she hooked up with "doobie", and is now pregnant with a baby girl. AFAIK from FB, they are still living with his parents. Good luck, kiddo.
