Michael Ware is in Mexico where he continues to dig deeper on the drug violence plaguing the country. The cartels are big business in Mexico, but it’s not just drugs anymore. They have branched out into other areas — like human smuggling.

Some believe this is contributing to the spike in violence against U.S. border patrol agents. Michael Ware will have more for us tonight.
