Libby, I found an article from Oct. 2007 on Noticaribe saying that his extradition was to proceed:
Noticaribe: Chetumal: Notifican a Mario Villanueva que s? procede su extradici?n. But, I think you're right, he's still in prison somewhere in Mexico awaiting extradition. I don't really follow it that closely, but it's a fascinating case, one court will exonerate him and another will immediately charge him again. You know how these cases go, he could be extradited tomorrow or never.
Anyhow, sorry for the thread hijack, great photos as always. Look forward to seeing more.
