The eight murders in Maricopa County, AZ look to be tied to smuggling, as reported here.

Strangely enough, just a couple months ago, we had a headline like "Vigilantes Blamed for Killings." Of course, in the last article I get the feeling that they left a few things out, like the remainder of what Sheriff's department spokesperson Lt. J.J. Tuttle said. For another "balanced" report, see the "Vigilante drug bust reveals deteriorating situation along Mexico-US border" section here.
