June 11th, 1954, 8:00 in the evening. Ohio Penitentiary, Columbus. A young woman walks down a narrow prison corridor. She is not crying. She is not shaking. She is not begging for her life. She is calm. Her name was Betty Evelyn Butler, and on that night, she made history in the worst possible way.

 She became the last woman ever executed by electrocution in the state of Ohio, and the youngest woman ever put to death in Ohio’s entire history. She sits down one final time. She says three words. 10 minutes later, she was pronounced dead. But, here is the question that has haunted this case for over 70 years.

 Was Betty Butler a cold-blooded killer, or was she a desperate young mother who had simply run out of options? What you are about to hear will make you question everything you think you know about justice. Welcome back to Red Mark files. If you are new here, this is where we go deep into the true crime cases that history almost forgot.

 Hit that subscribe button and turn on your notifications, because you do not want to miss a single story we bring you. Stay with me. Before we talk about what happened at that lake, you need to know who Evelyn Clark was. Evelyn was born around 1917 in Cincinnati, Hamilton County, Ohio. By the time this story begins, she was 35 years old, living in the West End, one of Cincinnati’s older, tightly knit neighborhoods.

 Evelyn was not struggling, not like Betty was. She had a home. She had money. She had enough financial stability to make offers that other people, desperate people, could not easily refuse. Court records describe her as someone with the means to house and pay others. That kind of economic power mattered enormously in early 1950s Ohio.

 Now, how did she meet Betty? It was not a chance encounter on the street. Evelyn reportedly sought Betty out at a time when Betty had nothing, no husband, no home, no money, two young children, and nowhere to turn. Evelyn made her an offer. According to court records, she proposed that Betty and her two children, daughter Quovodas and son Donald, could come and live with her in exchange for sex.

 Betty accepted because she had no other choice. But here is what we must not forget. Evelyn Clark was a real person. She was 35 years old. She had a life. She had a story that goes far beyond what court documents recorded. Whatever her flaws, she did not deserve to die at the edge of a lake while fishermen watched in horror. The arrangement started as a roof over Betty’s head, but it quickly became something far more dangerous.

 Arguments, jealousy, tension that never cooled. But behind closed doors, things were unraveling fast, and what was building between these two women would end in front of an audience no one expected. So who was Betty Evelyn Butler? Really. Betty was born around 1928, making her just a young woman in her early 20s when all of this unfolded.

 She grew up in Ohio with ties to both Cleveland and Cincinnati. On the surface, Betty looked like any other young woman of her time. She was a wife. She was a mother. She had two children, a daughter named Quovodas and a son named Donald. She was trying to hold a family together in a hard era for working class women. Her husband, identified in records only as Harry, was described as a strict Methodist.

 By all accounts, their marriage was not built to survive what came next because Betty, according to testimony presented in court, had been associating with other women in ways that her husband could not accept. When he found out, he reportedly threw her out. Just like that, the family was gone. The home was gone. Everything was gone.

 Betty ended up in Cincinnati without her children, without money, without a place to sleep. Court records used the same word over and over again to describe her situation at this point, destitute. That is the word that explains everything that followed. Now, testimony at trial suggested Betty was bisexual. In 1950s Ohio, that was not just socially unacceptable.

 It made her an outcast. It shaped how the court saw her, how the public saw her, how her own story was told. In prison, fellow inmates gave her a nickname, the Sphinx. Polite, quiet, never truly letting anyone in. Was Betty Butler a predator, a victim, or something too complicated for either label? That question is exactly what this case forces us to sit with.

 On paper, Betty finally had stability, a roof over her head, food on the table, a place for her children, Quovadis and Donald, to sleep at night. She and Evelyn Clark were now living together under one roof in Cincinnati’s West End. But stability was not what was happening inside that house. Court records document numerous domestic disputes between Betty and Evelyn.

 Not one or two disagreements, but a pattern of repeated, escalating conflict. Arguments that did not stop, tension that never fully left the room. And the reason was simple, this arrangement was never equal. Evelyn held all the power. She owned the home. She controlled the money. Betty had nowhere else to go. That kind of imbalance does not create peace, it creates pressure.

 Now, two very different stories emerged about what was happening between these two women. Betty’s version was this. Evelyn kept making unwanted sexual advances toward her, advances she did not want, advances she could not escape because she had no money and no options. But other testimony told a different story entirely.

 According to witnesses who took the stand, Betty was not an unwilling participant in this relationship. She was actively involved and she was growing increasingly jealous, particularly over Evelyn’s reported attention toward another woman. Two stories, one household, and two children. Quovadis and Donald caught in the middle of all of it, young, vulnerable, present in a home where anger had become the daily weather.

 What is perhaps most troubling is what did not happen. No one intervened. No authority was called. No shelter was sought. No one stepped in to stop what was clearly building toward something terrible. The warning signs were there. Everyone around them could feel it. Multiple people knew this situation was dangerous and yet nothing was done. Until September 6th, 1952.

Now, if you watch a lot of true crime, you know that many murder cases involve planning, secret meetings, hired killers, carefully built alibis. This case is different and it is important to be honest about that. Betty Butler did not sit down with an accomplice and plan Evelyn Clark’s death.

 There was no hired gun, no late-night strategy session, no written plan. Court records do not support that kind of premeditation. What we do know is this. On the morning of September 6th, 1952, Betty and Evelyn were not alone. A third person was with them, a man named Day Ivory. He was present that day. He went with them to Sharon Woods Park in Hamilton County, Ohio.

 Day Ivory was not a conspirator. He was a witness. He was there on the rowboat when the argument began. He was there when everything broke apart. His presence matters because he saw exactly what happened and what he saw, he later told in court. There was no master plan behind what took place at Sharon Woods Park that day.

 But make no mistake, what happened there did not appear from nowhere either. Weeks of arguments, months of a volatile, unequal, explosive relationship. The environment had been building toward to violent conclusion for a very long time. September 6th, 1952, Sharon Woods Park, Hamilton County, Ohio. It was an ordinary Saturday. Families were out.

 Fishermen sat quietly along the edge of the lake with their lines in the water. Children played. The park was calm, open, and full of regular people going about a regular day. Nobody came to Sharon Woods Park that morning expecting to watch someone die. Betty Butler, Evelyn Clark, and Day Ivory arrived at the park together.

The three of them got into a rowboat and pushed out onto the lake, but nothing about that boat ride was peaceful. They had been drinking, and the tension that had been living inside that West End household for months, the arguments, the jealousy, the power imbalance, had come with them onto that water. An argument broke out on the boat.

According to testimony presented in court, the dispute centered on jealousy, on the complicated and explosive dynamic between Betty and Evelyn. Words were exchanged. Voices rose. It became so bad that Day Ivory picked up the oars and rowed them back to shore. He was trying to stop it, trying to create distance, trying to bring the temperature down before something terrible happened.

 It did not work. The moment they reached land, Betty attacked Evelyn. Court records confirm what happened next. Betty pulled out a handkerchief and wrapped it around Evelyn’s neck. She strangled her, tightening it until Evelyn lost consciousness and went limp. But Betty was not finished. A pathologist who later examined Evelyn’s body confirmed that while there were clear signs of strangulation, the official cause of death was drowning.

Evelyn Clark was still alive when she hit the ground. Betty grabbed Evelyn by the ankles and dragged her body across the ground toward the lake. The fishermen on the shore saw this. The park visitors saw this. People stood and watched, frozen, as Betty pulled an unconscious woman to the water’s edge. Then Betty forced Evelyn’s head beneath the surface and held it there.

 One witness heard Betty say loudly and clearly, “If I can’t strangle her, I’ll drown her.” Those words are recorded in court documents. She held Evelyn’s head underwater. She did not let go. Evelyn Clark, 35 years old, drowned in Sharon Woods Lake while people stood watching in horror. Park rangers rushed over.

Bystanders attempted resuscitation. They worked desperately to bring her back. It was too late. As Betty walked away from the lake, witnesses heard her say, “My work is done.” Take a moment with those words. “My work is done.” Because two years later, on the night of her execution, those would be the exact same words she chose as her last.

 Betty Butler was arrested the same day, September 6th, 1952. She did not run. She did not deny what she had done. She simply said she had no choice. She committed this murder in front of witnesses, in broad daylight, in a public park. And yet, what she said next nearly changed everything. Betty Butler did not fall apart after her arrest.

 She did not cry. She did not scream. She did not beg. She was calm, controlled, the same quiet, guarded woman that prison inmates would later call the Sphinx, even in those first hours after the murder. That mask was already in place. Her legal defense came together quickly. Betty told investigators that Evelyn Clark had made repeated unwanted sexual advances toward her, that she had been essentially purchased, her body traded for a roof over her children’s heads, that killing Evelyn was not murder, it was self-defense. But this was 1952 in

Ohio. Courts in that era were not prepared to hear arguments about sexual coercion between two women. The language of domestic abuse and exploitation did not exist in courtrooms the way it does today. Betty’s defense was both morally complicated and legally fragile, and prosecutors knew it. Meanwhile, what about Quo Vadis and Donald? Betty’s two children had been living in that same house.

 Now their mother was in custody and their caretaker was dead. What happened to them after September 6th, 1952? Court records are largely silent and that silence is its own kind of tragedy. As for Evelyn Clark’s family, records tell us very little about their response. But she was 35 years old. Someone loved her. Someone mourned her. Back in Cincinnati’s West End, newspapers were already telling their version of the story calling it a sex revenge murder, splashing it across their pages.

 Betty Butler had not yet stood trial, but in the court of public opinion, she was already convicted. Most murder investigations start with a mystery, detectives searching for a suspect, forensics teams combing through evidence, weeks, sometimes months of work before anyone is charged. This case was different.

 Betty Butler was arrested on the same day the murder took place. She did not run. She did not deny what she had done. There was no missing suspect, no cold trail, but that did not make the investigation simple because there were two competing stories and the court had to decide which one was true. The prosecution built their case on four solid pillars.

 First, multiple eyewitnesses, fishermen and park visitors who stood at Sharon Woods Lake and watched the attack happen in front of them. Their accounts were consistent. Second, Day Ivory, he was on that rowboat. He heard the argument. He saw the moment everything broke apart. And he could testify to all of it. Third, Betty’s own words, “If I can’t strangle her, I’ll drown her.

” Spoken out loud, heard by witnesses, recorded in court documents. Fourth, the pathologist’s report, strangulation was confirmed, drowning was confirmed as the cause of death. Betty’s defense pushed back. She was a desperate mother with nowhere to go. She had been coerced into a sexual arrangement just to survive. Evelyn had made unwanted advances.

 The killing, she said, was defensive, but there was a problem with that argument and it was impossible to get around. You cannot claim self-defense when you drag an unconscious woman to a lake and hold her head underwater in front of witnesses. Ohio law was clear and prosecutors pointed to one more thing, Betty’s behavior after the murder.

 No tears, no remorse, no breakdown. Just silence, just calm. The Sphinx. Even then, in most true crime cases, there is a breakthrough moment, a DNA match, a confession, a witness who finally comes forward after years of silence. This case did not need any of that. The breakthrough here was simpler and more devastating.

 It was the moment the prosecution’s case became impossible to argue against. Here is what the evidence looked like when it was laid out together. Multiple witnesses, fishermen, park visitors, all told the same story independently, consistently. They saw the strangulation. They saw the dragging. They saw the drowning. Not one witness, not two, multiple people all saying the same thing.

 Day Ivory testified about what happened on that rowboat before they even reached the shore. The argument, the escalation, the moment he knew something was about to go very wrong. The pathologist confirmed it all in clinical detail. Strangulation first, then drowning, exactly as the witnesses described.

 And then there were Betty’s own words, spoken in a public park, heard by strangers, and handed directly to the prosecution. Betty Butler had condemned herself. Her self-defense claim could not survive the evidence. You cannot fear someone who is already unconscious. You cannot claim panic when you make a deliberate decision to walk someone to a lake.

 A grand jury in Hamilton County, Ohio, formally indicted Betty Butler on a charge of first-degree murder. The case was going to trial and the prosecution was carrying overwhelming evidence through that courtroom door. Betty Butler stood trial in Hamilton County, Ohio, charged with first-degree murder. Her defense team built their argument on three pillars. First, self-defense.

Evelyn Clark had made unwanted sexual advances. Betty was simply protecting herself. Second, coercion. Betty had entered this arrangement out of pure desperation. She was a destitute young mother with nowhere to go and no way to survive. The relationship was exploitative from the beginning. Third, provocation.

 Even if the jury could not accept full self-defense, the circumstances of her life, the poverty, the power imbalance, the pressure, should at minimum reduce the charge. The prosecution dismantled every single pillar. Self-defense, an unconscious woman cannot make advances. Evelyn was already on the ground when Betty dragged her to the lake.

 There was nothing left to defend against. Coercion, the witnesses at Sharon Woods Park did not see a woman in fear. They saw a woman in rage. Provocation, multiple consistent witness accounts, including Day Ivory’s testimony from the boat, destroyed any argument that this was an uncontrollable moment of panic. The jury deliberated.

 Then they returned their verdict, guilty. First-degree murder. Betty Butler was sentenced to death by electrocution and remanded to the Ohio Reformatory for Women in Marysville, the state’s facility for women on death row. She appealed. Her execution was postponed more than once over the following 2 years. But the grounds of those appeals did not hold. One by one they were denied.

 The sentence stood. This was 1952 Ohio. Courts had no framework for trauma, coercion, or domestic abuse the way we understand those things today. The law was straightforward, and it was final. Betty Evelyn Butler was 26 years old. She would become the youngest woman ever executed in Ohio’s history. Betty Butler spent approximately 2 years on death row at the Ohio Reformatory for Women in Marysville.

2 years of waiting. Fellow inmates and prison staff described her the same way consistently. Polite, reserved, distant. She rarely engaged with the other women around her. She answered when spoken to, but she never opened up, never let anyone truly in. They called her the Sphinx, but something was happening inside Betty during those two years.

Something quiet and private. She converted to Catholicism. She requested access to Chaplains. She was given a rosary and she kept it close, held it during the long silent hours that filled her days on death row. Her appeals ran their course and failed. The governor of Ohio did not step in.

 There was nothing left between Betty Butler and the electric chair. June 11th, 1954. Her last meal was requested and prepared. Betty chose scrambled eggs with cheese, a piece of toast, two glasses of milk and a dish of apricots. Simple, quiet, deliberately chosen. At 8:00 in the evening, Betty rose from her cell for the last time.

 She was dressed not in prison gray, but in a pink and black print dress, white Oxford shoes, and white bobby socks. She had chosen what she would wear to die. She held her rosary. Two Chaplains fell into step beside her, one on each side, as she walked the corridor to the execution chamber. That walk is called the last mile. Betty walked it without breaking.

Inside the chamber, witnesses sat in silence. Betty took her seat. She was secured. She did not scream. She did not beg. She did not break down. Her final words were four simple words. The same four words that witnesses had heard her say at the edge of Sharon Woods Lake two years earlier. My work is done.

 The switch was thrown at 8:10 in the evening, exactly 10 minutes after she sat down, Betty Evelyn Butler was pronounced dead. She was 26 years old. In that moment, she became two things that no woman in Ohio had ever been before or has been since. The last woman executed by electrocution in the state of Ohio.

 The youngest woman ever put to death in Ohio’s entire history. A As for Day Ivory, the man on the boat who witnessed everything, court records show he was never charged. His role was that of a witness, nothing more. After Betty, Ohio would not execute another woman for decades. The electric chair was eventually retired.

 The last woman Ohio ever electrocuted was 26 years old, wearing white bobby socks, and holding a rosary. June 11th, 1954, 8:10 in the evening, a 26-year-old woman is gone. Evelyn Clark, 35 years old, drowned at Sharon Woods Park on September 6th, 1952. She never came home. Her story is often reduced to a footnote in Betty’s. She deserves more than a footnote.

 Quo Vadis and Donald, Betty’s two children, disappeared from the historical record after their mother’s arrest. What happened to them? Nobody knows. That silence is its own kind of tragedy. Betty’s final words on execution night were the same words heard at that lake. My work is done. Whether that was defiance, peace, or something else entirely, only she knew.
