An avowed white supremacist convicted of a notorious racist murder -- chaining a black man to the back of a pickup truck and dragging him to his death -- was executed on Wednesday in the US state of Texas.
John William King, 44, was put to death by lethal injection at 7:08 pm Central Time (0008 GMT Thursday) at the Texas State Penitentiary in Huntsville, Texas.
King was one of three white men convicted of carrying out the 1998 murder of James Byrd Jr., one of the most gruesome racist killings in recent US history.
Lawrence Brewer was executed in 2011 while Shawn Berry -- who cooperated with investigators -- was given life in prison.
Berry testified during his trial that he and the two others were out drinking beer and cruising in a 1982 Ford pickup truck when they picked up Byrd, who was hitchhiking, and drove him to a remote country road.
The men severely beat the 49-year-old Byrd before chaining him by his ankles to the back of the truck.
Byrd was alive for some two miles (3.2 kilometers) while being dragged along the road, a pathologist testified during King's trial.
He was decapitated when his body hit a concrete drain pipe, the pathologist said.
Byrd's dismembered body was found outside a black church in the small town of Jasper, Texas, near the border with Louisiana.
The killing horrified the US public and kindled memories of the era of racist lynchings of African Americans in the South.
Ten years after King's conviction, president Barack Obama signed a law aimed at preventing hate crimes which was named after Byrd and Matthew Shepard, a young gay man murdered the same year.
In a request for a stay of execution filed with the Supreme Court late Tuesday -- which was ultimately denied -- King's lawyer, A. Richard Ellis, claimed that King's attorney during his 1999 trial ignored his request to plead not guilty.
"From the time of indictment through his trial, Mr King maintained his absolute innocence, claiming that he had left his co-defendants and Mr Byrd some time prior to his death and was not present at the scene of the victim's murder," Ellis said.
"Despite Mr King's explicit and repeated requests, his counsel conceded his guilt to murder at trial."
Repeated efforts to have King's conviction overturned had failed, with the Supreme Court refusing to examine the case in 2018.
On Monday, the Texas Board of Pardons and Paroles unanimously refused to grant him a reprieve.
During the sentencing phase of King's trial, his attorneys argued that prison violence had compelled him to hook up with a white prison gang.
"He wasn't a racist when he went in, he was when he came out," said his attorney, H. "Sonny" Cripps.
King's body is covered with racist tattoos proclaiming "Aryan Pride" and his allegiance to the Ku Klux Klan and a racist group known as the Confederate Knights of America. One tattoo is of a black man hanging from a noose.
The 1999 death sentence for King was the first in Texas since the 1970s handed to a white man for killing a black man.
Two of Byrd's sisters and a niece witnessed King's execution, the fourth so far this year in the United States.
"Today, we witnessed the peaceful and dignified execution of John King for the savage, brutal murder of James on June 7th 1998, really a modern-day lynching," Carla Byrd Taylor -- one of the victim's sisters -- said in a statement she read after the execution.
"King showed no remorse then and no remorse tonight. His execution is a just punishment for his actions," said Taylor.
