The state of Alabama executed Kenneth Eugene Smith on Thursday evening, making him the first person in history to be put to death by nitrogen gas, a method that produced a scene of violent convulsions and has ignited a firestorm of international condemnation.
The execution, carried out at William C. Holman Correctional Facility in Atmore, was the culmination of a 36-year legal odyssey rooted in a murder-for-hire plot that was as sordid as it was tragically simple. Smith, 58, was pronounced dead at 8:25 p.
m. local time, roughly 29 minutes after the nitrogen gas began flowing into a sealed mask strapped to his face, a process that witnesses described as anything but the peaceful passing the state had promised.
Witnesses reported that Smith, strapped to a gurney, began shaking and writhing violently for several minutes as the gas displaced the oxygen in his body. His body convulsed, his fists clenched, and he appeared to struggle against his restraints, a stark contrast to the “humane and painless” method that Alabama officials had touted in the months leading up to the execution.
The execution was the second attempt on Smith’s life. In November 2022, the state aborted his lethal injection after officials spent hours unsuccessfully trying to insert an IV line into his veins. That failure, coupled with a nationwide shortage of lethal injection drugs, pushed Alabama to adopt nitrogen hypoxia, a theoretically untested method that had been authorized by the state legislature but never used on a human being.
Smith’s legal team fought desperately in the hours leading up to the execution, arguing that the untested protocol violated the constitutional ban on cruel and unusual punishment. They asserted that the state was using Smith as a guinea pig for an experimental procedure with no scientific basis for its claim of painlessness. The U.
S. Supreme Court, in a 5-4 decision, rejected the final appeal, clearing the way for the unprecedented execution to proceed.
The story of how Smith arrived at this moment is a dark tapestry of betrayal, greed, and a justice system that many argue failed at every turn. It begins not with Smith, but with a respected Alabama pastor named Charles Sennett Sr., whose secret life of debt and infidelity led him to a chilling conclusion: the solution to his problems was the death of his wife, Elizabeth Dorlene Sennett.
Elizabeth was a 45-year-old woman living a quiet, unassuming life in Sheffield, Alabama. She was a devoted wife and mother of two adult sons, deeply embedded in her community and her church, where her husband preached every Sunday. She trusted her husband implicitly, a trust that would prove fatal.
In March 1988, Charles Sennett, facing financial ruin and the potential exposure of an 𝒶𝒻𝒻𝒶𝒾𝓇, devised a plan to have his wife murdered. He approached his tenant, Billy Gray Williams, and offered him money to carry out the killing. Williams, in turn, recruited two other men, John Forrest Parker and Kenneth Eugene Smith, promising each a share of the payment for their roles in the plot.
The plan was set in motion on March 18, 1988. Charles Sennett told his wife that two men would be coming by the property to look at some hunting land, a mundane and believable excuse in rural Alabama. When Smith and Parker arrived, they were calm and cordial, playing their parts as prospective hunters.
Elizabeth, ever cautious, called her husband to confirm their story. He told her it was fine, to let them look around.
That single phone call was the fulcrum of the tragedy. Elizabeth had done everything right, she had checked, she had verified, and the one person she trusted to give her the truth lied to her face, knowing full well what the two men were there to do. After walking the property, the men asked to use the bathroom.
Once inside, the facade shattered.
Parker engaged Elizabeth in conversation while Smith retrieved a fireplace tool and a stick. They beat her mercilessly. When she fought back, they continued their assault, ultimately stabbing her eight times in the chest and twice in the neck.
The attack was brutal, prolonged, and deeply personal, a far cry from the quick, clean killing Charles had envisioned. The men then staged the scene to look like a burglary, stealing a VCR and a stereo before fleeing.
Sheriff Ronnie May arrived at the scene and immediately sensed the staging was a lie. The violence was too specific, too rage-filled to be the work of random burglars. The investigation quickly turned toward the grieving husband, whose performance of shock and sorrow began to crack under the weight of pointed questions.
When investigators casually asked if he knew a man named Kenneth Smith, Charles Sennett’s composure shattered.
He left the interrogation, went to his church, and in front of his sons and his congregation, confessed to the 𝒶𝒻𝒻𝒶𝒾𝓇, the debt, and the plot to 𝓀𝒾𝓁𝓁 his wife. He then walked to his truck and shot himself in the head. The mastermind of the murder never faced a jury, never stood trial, and never had to answer for the chain of events he set in motion.
He escaped accountability in the most final way possible, leaving the three men he hired to face the consequences of his plan.
Billy Gray Williams, the intermediary, was sentenced to life in prison without parole. He died quietly in prison in 2020, a footnote in a case that would eventually capture global attention. John Forrest Parker was sentenced to death and executed by lethal injection in 2010, offering a brief apology before he died.
Only Kenneth Smith’s case would take a path so convoluted that it would redefine the debate over capital punishment in America.
Smith was initially convicted and sentenced to death in 1989, but that conviction was overturned on appeal. At his second trial in 1996, the jury voted 11-1 to sentence him to life in prison instead of death. The jury, having heard all the evidence, had decided that Smith did not deserve to die for his role in the murder.
But under Alabama law at the time, a judge had the power to override that decision. Judge Kenneth Jones did just that, sentencing Smith to death despite the jury’s recommendation.
This judicial override, a practice that allowed a single person to overrule the collective judgment of twelve citizens, was later abolished by the state of Alabama in 2017, a tacit admission that it was fundamentally flawed and unjust. But the change was not retroactive. Smith remained on death row, sentenced to die by a system that the state itself had deemed too broken to continue.
For decades, Smith’s appeals wound their way through the courts. He was granted stays, his case was reviewed, and he remained in a legal purgatory, waiting for a resolution that never seemed to come. The state’s inability to obtain the drugs necessary for lethal injection created a new crisis, one that would ultimately lead to the night of his execution.
Alabama, along with several other states, had authorized nitrogen hypoxia as an alternative execution method, but none had ever used it. The theory was simple: if a person breathes pure nitrogen, they will be deprived of oxygen and die. Proponents argued it would be quick and painless, a peaceful drift into unconsciousness.
Opponents, including medical experts and human rights organizations, warned that it was an untested, experimental procedure with a high risk of causing extreme suffering.
Smith’s legal team fought to stop the execution, arguing that the state was using him as a test subject. They presented expert testimony that the method could cause a sensation of drowning, panic, and asphyxiation. They argued that the state’s protocol was vague and incomplete, leaving too much room for error and cruelty.
The courts, however, were unmoved, and the execution proceeded as scheduled.
As the hour of his death approached, Smith was given a final meal of steak, hash browns, eggs, and a dinner roll. Outside the prison, protesters gathered, holding signs that called the execution torture and a macabre experiment. Inside, Smith was strapped to a chair, his face covered by a mask connected to a supply of nitrogen gas.
When asked if he had any final words, he spoke calmly, saying that Alabama was taking a step backward for humanity and that he was leaving with love, peace, and light.
Then the gas began to flow. For the first few seconds, nothing happened. Then, witnesses reported, Smith began to shake.
His body convulsed, his legs kicked against the restraints, and his chest heaved as he struggled for breath. The peaceful death promised by the state did not materialize. Instead, there were minutes of visible, violent struggle before his body finally went still.
The execution took 29 minutes from start to finish, making it one of the longest in the state’s modern history. Alabama officials declared the execution a success, calling it a legal and humane method that had worked as intended. Attorney General Steve Marshall said justice had been served.
Governor Kay Ivey defended the decision, stating that Smith had received the method he had requested.
But the eyewitness accounts told a different story. Civil rights groups and international observers described a scene of agony, a method that appeared far less controlled and far more painful than the state had promised. The United Nations human rights office condemned the execution, calling it a form of torture and urging a complete ban on the method.
The stark divide between the state’s official narrative and the reality witnessed by reporters in the room has only deepened the controversy.
The execution of Kenneth Smith was not a triumph of justice, but a grim and unsettling conclusion to a case that has haunted Alabama for nearly four decades. It was a case where the mastermind escaped judgment, where a jury’s decision was overruled by a single judge, where a failed execution attempt was followed by an experimental one, and where the ultimate price was paid by a man whose fate was sealed by a legal system that has repeatedly shown its fallibility.
In the aftermath, Elizabeth Sennett’s son, Charles Sennett Jr. , described the day as bittersweet, a day he had waited 36 years for, but one that brought no real closure. His words captured the profound emptiness of the moment.
There was no sense of a clean resolution, only the exhaustion of a long and painful journey finally ending, not with a sense of justice, but with a sense of weariness.
The story of Kenneth Smith’s execution is not ultimately about him. It is about Elizabeth Sennett, a woman who trusted her husband and paid for that trust with her life. It is about a pastor who chose murder over honesty and then escaped all consequences.
It is about a justice system that allowed a single judge to overrule a jury, that failed to carry out an execution, and that then turned to an untested and brutal method as a solution. It is a story of how a decision made in a living room in 1988 led to a man strapped to a chair, breathing nitrogen while the world watched, and how the system designed to deliver justice instead delivered a spectacle of suffering that has left more questions than answers.
