The gruesome case of a man who was stabbed and beheaded in a suburban Phoenix apartment has police investigating whether the killing is potentially the most extreme example of Mexican drug cartel violence spilling over the border.
The killing could also affect the immigration debate in Arizona. Supporters of the state's controversial immigration law frequently cite this type of violence as reason to crack down on illegal immigrants. The decapitation victim and the suspects were all illegal immigrants.
