Yeah, I don't know about Mex Mafia, but there are Cartels (same thing really), the most wicked and notorious being Los Zetas.
Hence, we'll see a lot of images of dead people with the letter 'Z' carved in them or notes pinned to victims with knives.
The Zeta's usually leave a very sick message, heads wrapped in plastic and duct tape.
A hellish suffocation...
Hand's cuffed, lots of mutilation and chopped up body parts.
I don't know what's going on here, it's benign compared to other cartel murders, if that's even the case.
And what's that on the ground behind the dead dudes?
Looks like some kind of surface to air weapon.
