The Death Penalty

Gas Chamber

In 1924, the use of cyanide gas commenced as Nevada sought a more humane way of executing its inmates. Gee Jon was the first person executed by lethal gas. The state tried to pump cyanide into Jon's cell while he slept. This proved impossible because the gas leaked from his cell, so the gas chamber was constructed. Today, five states authorize lethal gas as a method of execution, but al have lethal injection as an alternative method. A federal court in California found this method to be cruel and unusual punishment.

For execution by this method, the condemned person is strapped to a chair in an airtight chamber. Below the chest rests a pail of sulfuric acid. A long stethoscope fastens to the inmate so that a doctor outside the chamber can pronounce death. Once everyone has left the chamber, the room is sealed. The warden then gives a signal to the executioner who flicks a lever that releases crystals of sodium cyanide into the pail. This causes a chemical reaction that releases hydrogen cyanide gas. The team instructs the prisoner to breathe deeply to speed up the process. Most prisoners, however, try to hold their breath, and some struggle. The inmate does not lose consciousness immediately.

According to former San Quenton, California, Penitentiary warden, Clifton Duffy, "At first there is evidence of extreme horror, pain, and strangling. The eyes pop. The skin turns purple and the victim begins to drool." Caryl Chessman, before he died in California's gas chamber in 1960 told reporters that he would nod his head if it hurt, and the witnesses said he nodded his head for several minutes, Dr. Richard Traystman of John Hopkins University School of Medicine said, "The person is unquestionably experiencing pain and extreme anxiety... The sensation is similar to the pain felt by a person during a heart attack, where essentially the heart is being deprived of oxygen."

The inmate dies from hypoxia, the cutting-off of oxygen to the brain. At postmortem, an exhaust fan sucks the poisoned air out of the chamber, and ammonia covers the corpse to neutralize any remaining traces of cyanide. About half an hour later, orderlies enter the chamber, wearing as masks and rubber gloves. Their training manual advises them to ruffle the victim's hair to release any trapped cyanide gas before removing the deceased.
