Case Summary

Background

Luis Jose Monge was executed by asphyxiation-gas in Colorado on June 2, 1967.

Monge’s execution was the last execution both in Colorado and in the United States prior to the 1972 Supreme Court decision in Furman v. Georgia. It would be ten full years before any state would carry out another execution and 30 years before Colorado itself would do so.

Monge’s execution was one of only two executions to occur in the United States in 1967. It was also the last execution by gas chamber in Colorado.

After his wife had discovered he’d had an incestuous relationship with one of their daughters, his wife discovered the incestuous relationship.
