Authorities have determined a man who was stabbed and beheaded in a suburban Phoenix apartment was killed for stealing drugs from a Mexican cartel, in a gruesome example of drug cartel violence spilling over the border.

Martin Alejandro Cota-Monroy, 38, stole 400 pounds of marijuana and some meth from a drug cartel while telling the cartel that the drugs had been seized by the Border Patrol, according to a Chandler police report released Wednesday.

The cartel found out Cota-Monroy had actually stolen the drugs and hired men to kidnap and kill him in Nogales, Mexico. But Cota-Monroy was able to talk his way out of being killed, saying he’d pay back the money and use his house for collateral, the report says.

But the house wasn’t Cota-Monroy’s and he fled to the Phoenix area, leading the cartel to hire assassins to go to Arizona, befriend Cota-Monroy and kill him.
