Botched Execution Horror: Serial Killer's Execution Room Evacuated

The gas chamber used to be the main method of execution across many US states, but this changed after the death of infamous serial killer Jimmy Lee Gray.

Even before committing his horrific crime, Gray was known for his violent tendencies and minor legal offences.

At the age of 19, Gray’s violent behaviour escalated when he brutally killed his 16-year-old girlfriend, Elda Louise Prince, in Arizona.

Despite the brutal nature of his act, he was released after serving a mere seven years of his 20-to-life sentence.

Less than a year later, he committed another atrocity. On June 25, 1976, three-year-old Deressa Jean Scales disappeared after being left alone for just a short while.

Although there was a period of uncertainty about her fate, it soon became tragically clear that something terrible had occurred.

Gray lured the little girl into his car, drove to an isolated location, assaulted her sexually, and then suffocated her by pressing her face into the ground.

During his interrogation, Gray broke down and confessed in an elevator, pleading: "If I take you to her, will you help me?", subsequently leading the officers straight to her remains.

His acts were so monstrous that even Gray's mother implored the courts to withhold mercy, expressing her plea for "no mercy" in letters to the officials.

The chilling scene inside the outdated gas chamber at Mississippi State Penitentiary shocked those present beyond measure.

A vertical metal pole was situated behind the execution chair. Critically, the setup lacked a headrest, providing no support, which meant nothing prevented Gray’s head from hitting the pole during convulsions.

At 12:10 am, cyanide pellets were released into acid beneath his seat. As the toxic gas enveloped him, Gray started convulsing violently.

His face contorted with pain. His body strained fiercely against the restraints.

Then, abruptly, he thrust his head backwards, repetitively smashing it against the metal pole, groaning with every strike.

With numerous appalled witnesses in attendance, officials decided to evacuate the chamber as the spectators could not endure watching the painful scene unfold.

Medical experts confirmed that his heart continued beating for a torturous 12 more minutes before he was eventually declared deceased.

A prominent execution expert later condemned the method, stating it was "so agonising we wouldn’t subject laboratory animals to it."

Within a year, the state of Mississippi moved to eliminate the use of gas chambers for future executions.
