The execution was carried out in silence, broken only by the whispered final apology of a mother who had killed her own children and then asked the state to take her life. At 9:28 p. m.
on May 2, 2000, Christina Marie Riggs became the first woman executed in Arkansas in 155 years, her death by lethal injection ending a case that has haunted the American justice system for decades.
She was 28 years old, a licensed practical nurse, and a mother of two. Justin Dalton Thomas was five. Shelby Alexis Riggs was two.
On the evening of November 4, 1997, inside a small home in Sherwood, Arkansas, Christina Riggs gave both children sedatives, then injected her son with potassium chloride. When he regained consciousness, she smothered him with a pillow. She did the same to her daughter.
She laid their bodies side by side in bed, wrote a suicide note, and then tried to 𝓀𝒾𝓁𝓁 herself with pills and an injection of the same chemical. The injection missed her heart, burning a hole through her arm. She collapsed, but survived.
Her mother arrived the next morning and made the discovery that set everything in motion.
Christina Riggs did not flee. She did not deny responsibility. From the moment she regained consciousness, she fully confessed.
Her trial began in June 1998 in Pulaski County, Arkansas, on two counts of capital murder. Her defense entered a plea of not guilty by reason of insanity, presenting multiple psychiatric experts who testified about severe clinical depression and post-traumatic stress disorder.
The trauma traced back to 1995, when Christina Riggs was part of the medical response team deployed after the Oklahoma City bombing. The Alfred P. Murrah Federal Building had been destroyed by a truck bomb, killing 168 people, including 19 children.
She assisted with victims, witnessing burns, injuries, and death on a scale most people never see. She received no counseling, no follow-up mental health care.
By the mid-1990s, those close to her noticed changes. She became withdrawn, isolated, exhausted. She worked long shifts as a nurse and came home to raise her children almost entirely alone.
The fathers were not consistently involved. She had few friends, no social life. Psychiatric evaluations later revealed persistent feelings of guilt, hopelessness, and emotional numbness.
She believed she had failed as a mother. She believed her children deserved better than what she could give them. The defense argued that her actions were driven by a distorted belief system caused by severe mental illness.
She didn’t 𝓀𝒾𝓁𝓁 out of rage or cruelty, but out of a twisted sense of mercy. She thought she was protecting them.
The prosecution painted a different picture. They argued that Christina Riggs planned the crime deliberately, that she knew what she was doing, that she made calculated decisions, choosing the method, obtaining the drugs, carrying out the act in stages. Mental illness, they said, does not erase intent.
The jury deliberated for less than an hour. They found Christina Riggs guilty on both counts.
But what happened next shocked everyone in the courtroom. During the sentencing phase, Christina Riggs made a decision that defied every instinct of survival. She refused to fight for her life.
She waved certain legal defenses. She declined to pursue prolonged appeals. And when given the opportunity to address the court, she told the jury she wanted the death penalty.
She stated that she wanted to be reunited with her children. She told the jury not to feel guilt for their decision. She said she deserved to die.
Mental health advocates would later argue that this was evidence of continued suicidal intent, that Christina was not of sound mind to make such a decision. But the court moved forward. The jury sentenced her to death.
Christina Riggs was transferred to the McPherson Unit, Arkansas’s women’s death row facility. It had been created specifically to house her. She was the only woman on death row in the state.
She spent less than two years there, an unusually short period compared to most death penalty cases, which often stretch into decades of appeals.
She waved nearly every appeal available to her. She declined clemency requests. She signed documents expediting her own execution.
Mental health advocates argued that this demonstrated she was still suicidal, that the state was effectively assisting in her death wish. The state disagreed. They argued she had been evaluated, found competent, and that her decision was legally valid.
On the morning of May 2, 2000, Christina Riggs woke knowing it would be her last day. Death Row staff followed protocol. She was monitored closely.
She was allowed visitors, though it is unclear who, if anyone, came to see her. For her final meal, she requested pizza, salad, pickled okra, strawberry shortcake, and a cherry limeade. It was reported that she ate calmly.
That evening, as the sun set over the Cummins Unit in Grady, Arkansas, preparations began. Witnesses were escorted into the observation room. Journalists, officials, and others legally permitted to attend.
The atmosphere was described as tense, quiet. Christina was brought into the execution chamber and secured to the gurney. An IV line was inserted into her arm.
At 9:28 p. m. , she was asked for final words.
Christina Riggs looked toward the witness area. Her voice was steady. She apologized for her actions.
She expressed love for her children. Her final audible words were directed to them, words meant to reach across the divide between life and death.
Then the lethal injection began. The execution was carried out using a three-𝒹𝓇𝓊𝑔 protocol. First, a sedative to render her unconscious.
Then a paralytic to stop breathing. Finally, potassium chloride to stop the heart. At 9:28 p.
m. , Christina Marie Riggs was pronounced dead. She was 28 years old.
The execution sparked immediate debate across Arkansas and beyond. Some called it justice. A mother who committed the ultimate betrayal, who took the lives of two defenseless children, faced the consequences of her actions.
Others called it a failure of the system. A mentally ill woman who needed treatment, not execution. They argued that the state had carried out a legally sanctioned suicide.
Christina Riggs became the first woman executed in Arkansas in 155 years. She joined a small number of women executed in the United States in the modern era, a group that remains statistically rare compared to male executions. Her case raised difficult questions that remain unanswered.
Should someone who is suicidal be allowed to wave their appeals? Can a person suffering from severe mental illness truly give informed consent to their own execution? Where is the line between justice and vengeance?
And does that line shift when mental illness is involved?
Legal experts, ethicists, and mental health professionals continue to debate these questions. There are no easy answers. This case leaves behind difficult questions about responsibility, punishment, and where justice truly begins and ends.
Two children lost their lives. A mother took those lives, then asked the state to take hers. Some see it as a closed case, a crime committed, a sentence carried out.
Others see it as a tragedy compounded, a failure to recognize mental illness, to provide adequate treatment, to intervene before it was too late.
From the transcript of Christina Riggs’ own words, the depth of her remorse and the complexity of her mental state is laid bare. She said, “No matter how you sugarcoat it, no matter she was depressed, she was this, she was that, doesn’t make up for the fact that I took two innocent people’s lives that were my babies.” She added, “I regretted every day that I didn’t pick up the phone and call my mama that night and tell her what I was doing.”
Those words came from a woman who had been prescribed antidepressant medication, but whose treatment was questioned in court. She had been suffering from severe clinical depression and post-traumatic stress disorder. She believed she had failed as a mother.
She believed her children would be better off dead than left behind if she took her own life.
The prosecution argued that Christina Riggs planned the crime, that she made deliberate, calculated decisions. The defense countered that her actions were driven by a distorted belief system caused by severe mental illness, that she didn’t 𝓀𝒾𝓁𝓁 her children out of rage or cruelty, but out of a twisted sense of mercy. She thought she was protecting them.
Experts emphasized one key detail. Christina did not attempt to flee. She did not deny responsibility.
She did not try to shift blame. From the moment she survived, she fully confessed. Then the trial took an unexpected turn.
The jury deliberated for less than an hour. They found her guilty. Then she asked for death.
During the sentencing phase, Christina Riggs made a decision that defied every instinct of survival. She waved certain legal defenses. She declined to pursue prolonged appeals.
And when given the opportunity to address the court, she told the jury something almost no one in her position ever says. She wanted the death penalty. She stated that she wanted to be reunited with her children.
She told the jury not to feel guilt for their decision. She said she deserved to die.

What remains undisputed is this. Justin Dalton Thomas was 5 years old. Shelby Alexis Riggs was two.
They are gone. And the woman who killed them is gone, too. The questions that remain are the ones we are still asking about how we treat mental illness in the justice system, about whether punishment can ever truly account for pain, and about what we owe to the most vulnerable among us, even when they have done the unthinkable.
This is the story of Christina Riggs, and it does not offer closure. It offers something harder, the need to keep asking what justice really means. The case of Christina Marie Riggs forces the nation to confront uncomfortable truths about mental health, the death penalty, and the limits of compassion.
Her execution, carried out after she voluntarily abandoned every legal avenue for life, stands as one of the most controversial in modern American history.
Arkansas had not executed a woman since the Civil War era. The state’s death penalty machinery was unprepared for her presence on death row. The McPherson Unit had to be reconfigured to house a single female inmate.
She spent her days in isolation, her only human contact with correctional officers and occasional legal visits. During those months, she reportedly refused to engage in any legal strategy that might delay her execution.
Mental health experts who evaluated her before the execution testified that she suffered from major depressive disorder, post-traumatic stress disorder, and a personality disorder with dependent features. They noted that she had a long history of suicidal ideation, dating back to her teenage years. The Oklahoma City bombing experience had shattered her psychological defenses.
She had watched children die, and she could not escape the images.
The defense argued that her decision to waive appeals was a direct result of her mental illness. She was not making a free choice, they said. She was acting on the same distorted thinking that led her to 𝓀𝒾𝓁𝓁 her children.
The state countered that she had been found competent by multiple psychiatrists, including those appointed by the defense. She understood the difference between life and death, and she chose death.
The legal battle over her competency reached the Arkansas Supreme Court, which ruled that she was mentally competent to make the decision to waive her appeals. The court stated that her desire to die did not necessarily mean she was incompetent. Many mentally ill individuals, they noted, still have the capacity to make rational decisions about their own legal matters.
But critics saw a pattern. Christina Riggs had attempted suicide after killing her children. She had told investigators that she wanted to die.
She had deliberately sabotaged her own legal defense. She had refused to allow her lawyers to present mitigating evidence. She had asked the jury to sentence her to death.
And then she had fast-tracked her own execution. To many, this was not an execution. It was a state-assisted suicide.
The case drew national attention from death penalty abolitionists, mental health advocates, and religious groups. Some petitioned for clemency, arguing that executing a mentally ill woman who wanted to die was a violation of basic human rights. Others argued that Christina Riggs had committed a heinous crime, that she had murdered two innocent children, and that justice required the full measure of the law.
Governor Mike Huckabee of Arkansas had the power to grant clemency. He reviewed the case, met with advisors, and ultimately decided not to intervene. He stated that the legal process had been thorough, that Christina Riggs had been found competent, and that the state had a responsibility to carry out the sentence.
The execution went forward as scheduled.
On the night of May 2, 2000, a small group of protesters gathered outside the Cummins Unit. Some held signs calling for an end to the death penalty. Others held signs reading “Justice for Justin and Shelby.”
The atmosphere was somber. Inside the execution chamber, the only sound was the steady hum of the machinery and the quiet breathing of witnesses.
Christina Riggs was wheeled into the chamber at 9:15 p. m. She was wearing a blue prison jumpsuit.
Her hair was pulled back. She looked around the room, at the witnesses, at the medical team, at the chaplain. She was asked if she had any final words.
She said, “I want to apologize to my family, to the families of my children, and to everyone I have hurt. I love my children. I am sorry.”
Then she closed her eyes.
The lethal injection began. The first 𝒹𝓇𝓊𝑔, sodium thiopental, was administered to put her to sleep. Within seconds, her breathing became shallow.
The second 𝒹𝓇𝓊𝑔, pancuronium bromide, paralyzed her muscles, including her diaphragm. Her breathing stopped. The third 𝒹𝓇𝓊𝑔, potassium chloride, stopped her heart.
At 9:28 p. m. , she was pronounced dead.
The medical examiner noted that the execution had been carried out without complications. The body was taken to the state medical examiner’s office for an autopsy. Christina Riggs had requested that her remains be cremated and that no funeral service be held.
Her ashes were later released to a family member who chose to remain anonymous.
In the days following the execution, the debate continued. Newspaper editorials across the country weighed in. Some praised the state for carrying out justice.
Others condemned the execution as a failure of the mental health system. The case was cited by both sides in the ongoing national debate over the death penalty.
Mental health professionals pointed out that Christina Riggs had shown clear signs of suicidal ideation for years. She had been prescribed antidepressants, but the treatment had not been adequate. She had not received therapy for PTSD.
She had been isolated, overwhelmed, and desperate. They argued that the state should have recognized her as a person in crisis, not a criminal deserving of execution.
Legal experts pointed out that the U. S. Supreme Court had not yet ruled on whether executing someone who is mentally ill is constitutional.
The Court had held that executing the intellectually disabled is unconstitutional, but had not extended that protection to people with mental illness. The question remains open.
Christina Riggs’ case continues to be studied in law schools, psychiatry departments, and criminal justice programs. It is often used as an example of the intersection between mental illness and the death penalty. It raises questions about the role of trauma, the adequacy of mental health care in the prison system, and the ethical limits of state punishment.
For the families of Justin and Shelby Thomas, there is no closure. The children are gone. Their mother is gone.
The only thing that remains is the memory of two young lives cut short by a woman who loved them, even as she killed them. In her final statement, Christina Riggs said she wanted to be with her children. In death, she has achieved that reunion.
But for the rest of us, the questions remain. How do we balance justice with compassion? How do we punish without causing further harm?
How do we protect the vulnerable, even when they have done the unthinkable? The case of Christina Marie Riggs does not provide answers. It only provides a painful, enduring reminder that the line between victim and perpetrator is not always clear.
She was a nurse who helped save lives. She was a mother who took lives. She was a woman who asked to die.
And on May 2, 2000, the state of Arkansas granted her request. The execution of Christina Riggs stands as a stark testament to the complexities of the human soul and the limitations of the legal system. It is a story that will not be forgotten.
