Christa Gail Pike, the woman who at 18 years old carved a pentagram into a classmate’s chest and bludgeoned her with a chunk of asphalt in a brutal 1995 murder, now has a concrete date with the executioner. The Tennessee Supreme Court has scheduled her death for September 30th, 2026, setting the stage for a historic and deeply divisive moment in the state’s criminal justice history. If the execution proceeds, Pike will become the first woman put to death by the state of Tennessee in over 200 years.
The announcement comes after three decades of legal battles, appeals, and a lifetime spent in near-total isolation on death row. At just 20 years old when she was sentenced, Pike was the youngest woman on death row in the United States at the time. Now, at 49, her case forces the state to confront uncomfortable questions about culpability, childhood trauma, and whether a person shaped by horrific 𝓪𝓫𝓾𝓼𝓮 can be held to the same standard as one who was not.
The crime that landed Pike on death row shocked even hardened investigators in Knoxville. On the night of January 12th, 1995, Pike, then 18, lured 19-year-old Colleen Slemmer to a remote, wooded area near the University of Tennessee’s agricultural campus. The pretext was a gesture of peace, an attempt to bury the hatchet over Pike’s irrational jealousy regarding her boyfriend, Tadaryl Shipp.
Slemmer, a kind and trusting young woman studying computers, went willingly.
What followed was a sustained, 30-to-60-minute ordeal of unspeakable torture. Pike and Shipp slashed Slemmer’s throat with a box cutter, tore off her clothing, and gagged her with Pike’s own hairband to muffle her screams. In a chilling display of ritualistic violence, they carved a three-inch pentagram into her chest and another into her forehead.
Slemmer, fighting desperately for her life, suffered extensive defensive wounds to her arms and hands throughout the attack.
Slemmer begged for her life, promising to walk home to Florida and tell no one if they would only let her go. Her pleas were met with cold indifference. In her later confession, Pike chillingly recalled that Slemmer “wouldn’t shut up,” and that she simply didn’t want to hear her talking anymore.
Pike then picked up a large piece of broken asphalt and brought it down on Slemmer’s head, again and again, until the pavement itself shattered from the force of the blows.
In the most macabre act of the entire night, Pike reached down and pulled a small fragment of Slemmer’s skull from the fatal wound, slipping it into her jacket pocket as a gruesome souvenir. She walked back to her dormitory, showed the piece of bone to friends, and reportedly danced and smiled as she recounted the details of the murder. The medical examiner later ruled the official cause of death as blunt force trauma to the head.
Colleen Slemmer was just 19 years old.
The investigation moved swiftly. Within 36 hours, Pike, Shipp, and a lookout named Shandalla Peterson were in custody. Blood matching Slemmer’s genetic profile was found on Shipp’s clothing, and the piece of skull was recovered from the pocket of Pike’s jacket.
Pike gave a lengthy, detailed confession, waiving her Miranda rights just two days after the murder. While she initially tried to minimize her role, the physical evidence and witness testimony painted a damning picture of calculated brutality.
Pike’s trial began in March 1996, and the evidence against her was overwhelming. On March 22nd, a Knox County jury found her guilty of premeditated first-degree murder and conspiracy to commit first-degree murder. Eight days later, she was formally sentenced to death by electrocution.
When the sentence was read, witnesses reported that Pike collapsed and sobbed uncontrollably, a stark contrast to the cold demeanor she had displayed in the aftermath of her crime.
Her co-defendants faced different fates. Tadaryl Shipp, who was 17 at the time of the murder, was ineligible for the death penalty under Tennessee law. He was convicted and sentenced to life in prison with the possibility of parole, plus an additional 25 years.
In October 2025, he was denied parole for the first time and will not be eligible for review again until 2031. Shandalla Peterson, who acted as a lookout, cooperated fully with investigators and testified against Pike and Shipp.
In exchange for her testimony, Peterson pleaded guilty to being an accessory after the fact and received a sentence of probation. She walked out of the courtroom a free woman, a fact that has continued to rankle those who believe all three bore equal responsibility for Slemmer’s death. This disparity in sentencing, where the primary instigator faces execution while a co-conspirator walks free, remains a central point of contention in the debate over Pike’s fate.
For the victim’s family, the long wait for justice has been a separate kind of torment. May Martinez, Colleen Slemmer’s mother, has spent three decades fighting to be heard. For years, she pushed Tennessee authorities to return the fragment of her daughter’s skull that was kept by the state as evidence, so that Colleen could finally be buried whole.
The fragment remained in state custody for decades, a painful reminder of a case that refused to reach its final chapter.
Beyond the original crime, Pike’s behavior on death row has done little to generate sympathy. In August 2001, she attacked a fellow inmate, Patricia Jones, attempting to strangle her with a shoestring. Pike claimed she had been tormented for years, but in 2004, she was convicted of attempted first-degree murder, adding a 25-year sentence on top of her existing punishment.
In 2012, corrections officials also uncovered an alleged escape plot involving Pike, a corrections officer, and an outside accomplice.
Yet, alongside this history of violence, Pike’s legal team has presented a narrative of profound trauma and documented mental illness. They argue that her actions were the product of a childhood marked by severe neglect, physical and sexual 𝓪𝓫𝓾𝓼𝓮, and a complete failure by the adults who were supposed to protect her. She was eventually diagnosed with bipolar disorder and post-traumatic stress disorder, conditions her attorneys argue trace directly back to the 𝓪𝓫𝓾𝓼𝓮 she suffered as a child.
Described as a “little girl who was failed by almost every adult who was supposed to protect her,” Pike’s history is undeniably tragic. Born prematurely in 1976, she spent her early years in squalid conditions, found crawling through animal waste as a baby while her mother drank. She was shuffled between relatives, changed schools constantly, and turned to drugs and alcohol at an alarmingly young age.
By the time she arrived at the Knoxville Job Corps center in 1994, she was a deeply damaged teenager seeking validation.
That need for validation was tragically fulfilled by Tadaryl Shipp, the first person who made her feel treasured. Their shared fascination with the occult, evidenced by pentagram necklaces and a shrine in Shipp’s dorm room, created an intense, obsessive bond. When Pike perceived Slemmer as a threat to that relationship, her jealousy curdled into a plan for human sacrifice, a plan she used to prove her devotion to both Shipp and their dark beliefs.
In September 2024, after decades of near-total isolation in a cell roughly the size of a parking spot, Pike reached an agreement with the state that allowed her a job inside the prison and more time out of her cell. These small changes, fought for over years by her legal team, came with the grim acknowledgment that the clock was still running. They were improvements to the quality of her waiting, not a reprieve from the ultimate sentence.
Her legal team has continued to fight her execution, arguing that her death sentence constitutes cruel and unusual punishment given her age at the time of the crime and her documented mental illness. One federal appellate judge noted a stark irony: had Pike been just one year younger, like her co-defendant Shipp, she would have been ineligible for the death sentence entirely. This arbitrary line of age, 18 versus 17, has become a powerful argument for those seeking clemency.
Advocacy groups have gathered thousands of signatures asking Tennessee’s governor to intervene, but so far, the courts have found no legal grounds to stop the execution. Pike herself has said she does not deny what she did and believes she deserves punishment. However, she argues that she should not be the only one to face execution for a crime three people committed together, when one walked free on probation and the other remains eligible for parole.
Pike has spent more of her life on death row than she ever spent free. She has had 30 years to reflect on the brutality of her actions, years to confront the demons of her childhood, and years to wait for a judicial system to decide her fate. The question now is whether the state of Tennessee will follow through on September 30th, 2026, making history by executing a woman whose status as a legal adult was only measured in months.
Under Tennessee law, because her crime was committed before January 1st, 1999, Pike has the right to choose her method of execution: lethal injection or the electric chair. If the execution proceeds, she will become the first woman executed in Tennessee since 1817 and the first person in the state’s modern history to be put to death for a crime committed at just 18 years old.
The case forces an uncomfortable question that remains unanswered: What do we do with a person who committed an unforgivable act as a barely adult teenager, shaped by a childhood no child should survive? There is no easy answer, and that is precisely why this case has stayed in the headlines for three decades, tearing at the conscience of courts, families, and a state still grappling with what justice truly means in the face of such profound evil and such profound suffering.
As the date approaches, the focus will intensify on the victim, Colleen Slemmer, the young woman who never got to finish her computer training, never got to go home to Florida, and never got to grow old. Her mother’s 30-year fight to be heard culminates now, not in a happy ending, but in a final legal reckoning. The state of Tennessee has spoken, and the only question that remains is whether a court, or a governor, will intervene before the ultimate penalty is carried out.
