Thanks for the link BGG. I'll quote from your link:
His ex-wife also says her husband did a lot of research on the JonBenet Ramsey case and also on Petaluma's own Polly Klaas.
Laura Karr also tells us she's devastated and embarrassed by these murder charges, but she does not believe that her husband did it. She says that during Christmas season of 1996 when JonBenet Ramsey was strangled and beaten to death in Colorado, they were living in Alabama at the time and she was with him the entire Christmas season.
Karr's brother was on the phone from an airport on Greta tonight (said he'll be interviewed tomorrow night on the show), and states there was a good family life in Alabama from 1989-2002. Never a known connection to Colorado or Ramseys. They had 2 young kids in Dec 1996 and it sounds impossible he could have been away unnoticed at Christmas for a trip to Colorado to see people he didn't apparently know. It's sounding right now much like someone wanting to get out of Thailand desperately over some trouble there, rather than a solved Ramsey case at this point. They'll have to make some connections to verify this no matter what he's saying.
