CHANDLER, Ariz. – 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.

Martin Alejandro Cota-Monroy’s body was found Oct. 10 in a Chandler apartment — his severed head a couple feet away. One man suspected in the killing has been arrested, and a manhunt is under way for three others.
