William Lonzo “Lon” Parker, a prominent Border Patrol officer, was killed in Arizona in 1926, allegedly by two Mexican residents. Legends surrounding his death called for brutal retaliation executions of seven ethnic Mexicans. Revenge-by proxy, a murderous Rangers practice accepted the death of any ethnic Mexican without cause of guilt. The violence practiced in the wake of Parker’s death was ignored, and his memory was celebrated.
