Three Maricopa County (Ariz.) Sheriff's employees, including a veteran patrol deputy, have been arrested in a drug-trafficking sting. Investigators believe they helped a Mexican drug cartel smuggle heroin and people into Arizona.
Deputy Alfredo Navarrette, 37, served in a special unit designed to target human smugglers moving through Maricopa County. Sheriff's detention officers Sylvia Najera, 25, and Marcella Hernandez, 28, were also arrested. Sheriff Joe Arpaio called his deputies' alleged actions "despicable."
