A man convicted of murder for the shooting of his girlfriend and her daughters in their Tennessee residence almost 40 years ago experienced agony when he was executed today.
Byron Black died at 10:43am Tuesday, roughly 10 minutes after the lethal injection started.
‘It’s hurting so bad,’ Black told a spiritual advisor at 10:33am as his execution began. He reportedly did not deliver a formal last statement.
The murderer, 69, looked around the room and could be heard sighing and breathing heavily, witnesses to his execution allege.
Black was convicted in the 1988 shooting deaths of his girlfriend Angela Clay, 29, and her two daughters, Latoya Clay, 9, and Lakeisha Clay, 6.
According to prosecutors, he acted out of jealousy when he killed the three individuals in their home. At that period, Black was on a work-release program while serving a sentence for the shooting of Clay’s estranged husband.
Black was executed after a back-and-forth in court over whether officials would need to turn off his implantable cardioverter-defibrillator, or ICD.
His lawyers contended that the device regulating his heart should be turned off to prevent a ‘torturous death’. They claimed it could administer a shock to his heart when the lethal substances were administered, causing undue suffering and delaying his death.
But last week a judge ruled in the state’s favor to execute Black without deactivating the device.

In recent years, Black’s legal team unsuccessfully tried to get a new hearing over whether he was intellectually disabled and ineligible for the death penalty under US Supreme Court precedent.
Black was in a wheelchair, suffering from dementia, brain damage, kidney failure, congestive heart failure and other conditions, his attorneys have said.
His attorneys said that if they had delayed a prior attempt to seek his intellectual disability claim, he would have been spared under a 2021 state law.
Nashville District Attorney Glenn Funk contended in 2022 that Black is intellectually disabled and deserved a hearing under that 2021 law, but the judge denied it.
That is because the 2021 law denies a hearing to people on death row who have already filed a similar request and a court has ruled on it ‘on the merits.’
In Funk’s attempt, he focused on input from an expert for the state in 2004 who determined back then that Black didn’t meet the criteria for what was then called ‘mental retardation’.

But she concluded that Black met the new law’s criteria for a diagnosis of intellectual disability.
Black also sought a determination by the courts that he was incompetent to be executed.
In mid-July, a trial court judge agreed with Black’s attorneys that officials must have the device deactivated to avert the risk that it could cause unnecessary pain and prolong the execution.
But the state Supreme Court intervened Thursday to overturn that decision, saying the other judge lacked authority to order the change.
The US Supreme Court also rejected Black’s final appeal Monday and Tennessee Gov. Bill Lee declined to stop the execution.
The nonprofit Death Penalty Information Center said it’s unaware of any other cases in which an inmate was making similar claims to Black’s about ICDs or pacemakers.
Black’s attorneys said they haven’t found a comparable case, either.

Black’s death was Tennessee’s second execution since May, after a pause for five years, first because of COVID-19 and then because of missteps by state corrections officials.
Twenty-eight men have died by court-ordered execution so far this year in the US, and eight other people are scheduled to be put to death in seven states during the remainder of 2025.
The number of executions this year exceeds the 25 carried out last year and in 2018. It is the highest total since 2015, when 28 people were put to death.
