First execution by lethal gas

The initial execution by lethal gas in American history is completed in Carson City, Nevada. The executed man was Tong Lee, an associate of a Chinese gang who was simply convicted of murdering a rival gang member. Lethal gas was adopted by Nevada in 1921 as an even more humane strategy of undertaking its death sentences, instead of the traditional tactics of execution by hanging, firing squad, or electrocution.

During a lethal gas execution, the prisoner is sealed within an airtight chamber and either potassium cyanide or sodium cyanide is dropped right into a pan of hydrochloric acid. This produces hydrocyanic gas, which destroys a human body’s capability to approach blood hemoglobin. The prisoner falls unconscious within minutes and chokes to death, unless she or he holds their breath, in which particular case the prisoner frequently suffers violent convulsions for to one minute before dying up.

Lethal gas as a method of undertaking capital punishment was largely replaced by lethal injection in the late 20th century.
