Forty-five years ago today, Luis Monge was gassed in Colorado for murder — the last execution in the United States before a decade-long lull in capital punishment in the U.S.
Monge, an insurance salesman with no prior history of violence, had a hearty brood of 10 children, but when his wife found out he was having an incestuous relationship with one of them, Monge bludgeoned the wife to death, and killed three of the young children just for good measure.
Monge pleaded insanity, and then when doctors found him sane enough to stand trial, just pleaded guilty — eventually dropping all appeals and asking to be hanged in public at the Denver City and County Building.
Despite the culprit’s preferences, his execution was stayed for all of 1966 while Colorado voters weighed a referendum on continuing the death penalty. They ultimately voted 3-1 in favor. (See this detailed history of the death penalty in the Columbine State.)
Even though Monge himself embraced execution willingly, his seven remaining children (also the children of, and siblings of, his victims: surely a difficult position) still fought for clemency, and shared Monge’s last meal with him.
Had Monge maintained his appeals, he — like four other Colorado inmates whose death dates were also on hold in 1966 — would likely have made it into the nationwide unofficial moratorium on executions that settled in while courts sorted out death penalty standards in the late 1960s and early-to-mid 1970s.* That period led into 1972’s landmark Supreme Court decision Furman v. Georgia, invalidating all existing death sentences in the country and sparing men much more nefarious than Luis Monge.
Instead, this date’s principal went to his death clutching a black rosary (and allegedly, and one must suspect apocryphally, asking if the gas would trouble his asthma)** and became a nigh-forgotten denouement from a closed chapter of death penalty jurisprudence, and the last man put to death in America until Gary Gilmore almost ten years later.
Apart from his milestone status vis-a-vis capital punishment nationwide, Monge is also the last person to die in the Colorado gas chamber.

In fact, Monge is currently still the second-last put to death in Colorado, period. It would be fully 30 years before Colorado executed again — in 1997, by lethal injection. As of this writing, it hasn’t done so again since.
* If Monge had avoided execution, the “last pre-Furman execution” milestone would be held instead by California’s Aaron Mitchell, the only man executed on the authority of California governor (and future U.S. president) Ronald Reagan.
** The man who pulled the lever for Monge’s execution, Canon City penitentiary warden Wayne Patterson, was not enthusiastic about the job. He describes his experience here, saying that “Monge was a guilt-ridden man who was nearly suicidal before he was executed. Those were the [kind of] guys who were executed — not the people I thought belonged in the chamber.”
