I'm An American living in mazatlan. I've been lurking but not posting. Kind of like better seen than heard. Looks like El Diablo has been captured. To find the article GOOGLE Cartel Del Golfo El Diablo. Things are peaceful here.
There are many people associated with the CDG with that nickname. One Diablo with clave L-9 (I think) was killed in the same shootout as el Karis in 2009, another one was captured last december and in that article they mention yet another one, from Michoacan. There is a Diablo active in the CDG in Matamoros right now who hasn't been killed or captured, it probably isn't the same person as the guy who's posting as CDG, but then again who knows.
