In Painful Execution, Attorney Says Byron Black was ‘Tortured’ by the State of Tennessee

Experts warned Black’s heart implant could shock him repeatedly during the lethal injection, but the Tennessee Supreme Court ruled the state could kill him without deactivating it

“Oh, it’s hurting so bad.”

Three minutes after Byron Black began receiving a lethal dose of pentobarbital in the execution chamber at Riverbend Maximum Security Prison on Tuesday, he lifted his head off of the gurney he was strapped to and groaned. Whether it was the effects of the drug, which can cause pulmonary edema or fluid in the lungs, or shocks to his heart from the defibrillator implanted in his chest, Black was in obvious distress. His spiritual advisor, Rev. Monica Coakley, sang to comfort him.

“I’m so sorry,” she said. “Just listen to my voice.”

Two minutes later, at 10:35 a.m., he raised his head and groaned again before lying back and becoming unresponsive. At 10:43 a.m., a doctor pronounced him dead.

His attorney, federal public defender Kelley Henry, said at a press conference after exiting the prison that her 69-year-old client had been “tortured.” 


The execution was carried out more than 35 years after Black was convicted and sentenced to death in Nashville for the murders of his girlfriend Angela Clay and her daughters, Latoya and Lakeisha. Black was on furlough from a Nashville jail facility when the murders occurred, and Angela had reportedly been considering reconciling with her estranged husband, Bennie Clay. Black had been sentenced to two years in jail for shooting Bennie during an altercation the year before. 

Henry had warned in court and in the media that Black’s defibrillator was likely to shock him repeatedly during the lethal injection if it was not properly deactivated, and the state attorney general’s office never contested Black’s medical experts. The Tennessee Supreme Court ruled last month that the state could kill him without deactivating his defibrillator. 

“Today, the State of Tennessee killed a gentle, kind, fragile, intellectually disabled man in violation of the laws of our country simply because they could,” Henry said after the execution, reading from a written statement. “No one in a position of power, certainly not the courts, was willing to stop them.”

Henry’s formal statement came after she fought back tears while relaying what she’d witnessed during the execution of a man she represented for 25 years. The people who made it possible, she said, “should feel shame.” Black, she said, had asked her to express his gratitude to his family, supporters and even the prison staff who had shown him kindness in his final days.

“Byron left this world with words of grace, mercy and love,” Henry said, “I wish I could share these sentiments. I do not. The State of Tennessee heartlessly and intentionally traumatized a second family today. A family that matters. A family that is devastated. May God have mercy on their souls. I know that he has mercy for Byron.”

“I thank God for this day, a day that was a long time coming. This was 37 years too late,” Dyer said in a statement provided by the family.

Demonstrators gathered in a fenced-in field adjacent to the prison, separated by prison officials into “pro-death penalty” and “anti-death penalty” groups. Approximately 25 people, including leaders of the nonprofit group Death Penalty Action, death row visitors and religious leaders who opposed Black’s execution, participated in a liturgy for him that included prayers for the Clay victims and family. 

“We pray for Angela Clay and her daughters Latoya and Lakeisha Clay, who died violent deaths,” read one portion of the liturgy. “Lift them to eternal peace, and grant that their goodness may continue to shine in those they loved.”

Relatives of the Clay family made up the “pro-death penalty” group, including Clay family cousins Nicoule Davis and Sharonda Page. Davis, who recalled playing with Latoya and Lakeisha Clay as a child, called the execution day a “celebration” that had been “a long time coming.”

Metro Councilmember Delishia Porterfield demonstrated alongside opponents and told the Banner she was there because she opposed state executions. She said she was grieving for both families involved. 

Before the 1989 trial, Black’s original attorney argued he was mentally incompetent for the proceedings, and that issue surfaced again in recent years as Black faced multiple execution dates. His intellectual disability was so well-documented — tests over the years found his IQ to be below 70 — that state attorneys had stipulated in a court filing that he would be deemed ineligible for the death penalty if a new hearing were held. Davidson County District Attorney Glenn Funk asked a judge to vacate Black’s death sentence in 2022 for the same reason. 

But courts denied Black’s appeals on that issue because the state’s current intellectual disability law does not apply to people who have had their competence adjudicated previously. His mental capacity had only been further diminished due to dementia. 

Black’s legal team also raised alarms about his physical condition as the execution date approached. He had been diagnosed with end-stage kidney disease and congestive heart failure. Doctors had placed an implantable cardioverter-defibrillator in his chest last year to treat his heart condition. Black had been rendered essentially immobile in recent years. 

Black’s day began at 4:45 a.m. with a final meal of pizza with mushrooms and sausage, followed by doughnuts and butter pecan ice cream. According to Henry, he participated in a church service in his cell. Other death row inmates reported seeing him wheeled off to death watch two weeks ago, and Henry said Tuesday that two prison guards had to hold him up as they took him to the gurney before his execution.

He was wheeled from his cell to the execution chamber at 10:07 a.m., where correctional officers placed two tight straps across his chest and taped his arms out from his side onto extensions for his IVs. His hands were heavily wrapped in tape to prevent movement. According to Henry, medical personnel had trouble finding the veins in both of his arms, leading to a puddle of blood on his right side. She said it took 10 minutes for the tubes to be attached, which first brought saline and then pentobarbital. 

As a sheet was placed over most of his body, Coakley told him, “You’re almost home.” 

Fourteen minutes later, he was.

USA | What happens in the final weeks before an execution? These reporters were inside the room.

The journalists behind ‘The Last 12 Weeks’ earned extraordinary access to a death penalty defense team—and faced difficult ethical choices Many defense lawyers are naturally cagey. They work in a pressure cooker, protecting their clients’ rights while fighting for the best possible outcome. And arguably, the stakes can’t get any higher than trying to save a client’s life. So no, defense lawyers don’t usually invite journalists into strategy meetings. But that’s what happened when Marshall Project reporter Maurice Chammah and Serial Productions senior producer Alvin Melathe spent the final few months before a Texas execution embedded with a capital defense team.

North Korea | 'I was only 9': North Korean defector recalls childhood memory of public execution

Kim Eun-joo was 9 years old when her teacher stopped their lesson and told the class to follow her outside. The children were marched to a public execution ground in North Korea. “I would cry even when our family dog died,” Kim said in a recent interview with The Korea Times. “But the first time I watched humans killing a human, I had no words for what I was feeling. It was the most brutal scene I have ever seen, in any movie or in real life.” The memory has stayed with her ever since. Now a human rights advocate after defecting from North Korea, Kim recently brought that childhood scene to the 9th World Congress Against the Death Penalty in Paris, where North Korea’s use of public executions and capital punishment was officially placed on the agenda for the first time.

19 July 1943 | Auschwitz's Largest Public Hanging: 12 Polish Prisoners Executed in Escape Reprisal

OSWIECIM, Poland — The SS carried out the largest public hanging in Auschwitz history on July 19, 1943, executing 12 Polish prisoners before other inmates as collective punishment for escapes and civilian contacts. The victims, all from the camp’s surveyors’ labor unit, were hanged on gallows built in front of the camp kitchen during an Auschwitz I roll call. The SS orchestrated this reprisal following prisoner escapes from the surveyors’ detail and unauthorized communication between inmates and civilians. Camp authorities used the recent escapes as a pretext to impose collective punishment.

Japan: Capital punishment for a minor

Death chamber at Tokyo Detention Center The Supreme Court's recent decision to uphold the death sentence given in a lay judge trial to a 24-year-old man for murders he committed when he was a minor raises questions about the lay judge trial system and capital punishment. These include whether the lay judges correctly understood the spirit of the Juvenile Law in sentencing the defendant to death. It was the 1st death sentence handed down on a minor in a lay judge trial. The murders took place in Ishinomaki, Miyagi Prefecture, in 2010 when Yutaro Chiba was 18 - meaning he fell under the purview of the Juvenile Law. Chiba was convicted of entering his ex-girlfriend's house and stabbing to death the girl's sister and a female friend of the girl with a butcher knife, seriously injuring a male friend of the sister and abducting the girl. Prosecutors said Chiba killed the victims because they were trying to separate him and his former girlfriend. Since Chiba pleaded n...

Texas: The inmates who refused to die quietly and had to be gassed out of their cells before execution

Former crime reporter Michelle Lyons, who witnessed nearly 300 executions in Texas, US, reveals the desperate acts of death row prisoners who refused to accept their fate After spending years or often decades locked up in a tiny cell for 23 hours a day, most Death Row inmates go willingly to their executions. However, some refuse to die quietly - with officers forced to gas them out of cells, strap up their heads and even give chase across prison grounds. Michelle Lyons, who has witnessed nearly 300 executions in Texas, US, exclusively tells Sun Online how certain inmates "fight like hell" in their last moments. On most occasions, Michelle watched from the witness area, with the killers already on the gurney - the stretcher where they'd be given a lethal injection. Seven prisoners once tried to escape from the Row in Huntsville - with one shoving magazines and newspapers under his clothes to help him roll over razor-wire fences. Others have had to b...

Idaho | Death row prisoners sue over state's new firing squad

BOISE (Idaho Statesman) – Days after Idaho made the switch to a firing squad for executions, two Idaho death row prisoners next in line to be put to death sued the state prison system, saying its director withheld information about how she settled on the specifics for carrying out the method. Attorneys for prisoners Thomas Creech and Gerald Pizzuto filed suit this week in state district court against Idaho Department of Correction Director Bree Derrick. In the filing, they called her approval of an updated standard operating procedure for the firing squad and lethal injection as a backup method “arbitrary, capricious, or an abuse of discretion and in excess of the statutory authority of the agency.”
