BISBEE, Arizona—Tired of waiting for the federal government to fix the border, Sheriff Mark Dannels decided to take matters into his own hands. A personal run-in with a Mexican cartel only cemented his motivation to rid his county of cross-border crime.
Five years ago, Dannels’s son, Sierra Vista police officer Justin Dannels, fatally shot a man allegedly connected to the Sinaloa cartel when the man tried to run him over during a traffic stop.
