New Mexico's final judicial hanging took place on September 21, 1909. The condemned man was Manuel Trujillo.
After statehood, New Mexico adopted the electric chair in 1929 (first use: 1933). Later, lethal injection became the sole method (1980s). The death penalty was abolished in 2009 (not retroactive); the last execution was in 2001.
Trujillo's execution closed a chapter of territorial justice. Frontier hangings—often public, sometimes extrajudicial—were already fading as legal procedures formalized. His is the last legal hanging recorded in New Mexico's history.
