"But why in tarnation would Mexican cartels use the AB when they have their own people here?"

I would offer the theory that it is the other way around. The AB would offer money to hire drug cartel hit men. The assassination could be carried out, and the murderer is back in Mexico before the investigation is even half way done. That's one way open borders work. Easy to get in, and easy to get out. And it would be difficult to pin on the AB.
