A man has been executed for the rape and murder of a 16-year-old girl who had been left stranded with a flat tyre.
Thomas Edwin Loden Jr, 58, from Mississippi, US, received a lethal injection at the Mississippi State Penitentiary shortly after 6pm local time (midnight GMT) for the killing of Leesa Marie Gray in June 22, 2000.
Wanda Farris, the victim's mum, watched the execution of her daughter's killer.
He is the second inmate in Mississippi to be executed in 10 years with the state's most recent killing in November 2021.
Loden has been on death row since 2001 after pleading guilty to capital murder, rape and four counts of sexual battery against 16-year-old Leesa Marie Gray.
Despite a last-minute attempt to block the execution on December 7, a federal judge allowed the killing to go ahead amid a pending lawsuit from Loden and four Mississippi death row inmates over the state's lethal injection protocol.
Gray was working as a waitress at her uncle's restaurant in northeast Mississippi on June 22, 2000 when she left work after dark and became stranded with a flat tyre on a rural road.
Loden, a Marine Corps recruiter with relatives in the area, saw the 16-year-old on the road at around 10.46pm and stopped to speak to the teen.
He said he would help with the flat tire and admitted: "Don't worry. I'm a Marine. We do this kind of stuff."
Loden told investigators he became angry after Gray allegedly said she would never want to be a Marine, and that he ordered her into his van.
He spent four hours sexually assaulting her before strangling and suffocating her, according to an interview he gave investigators.
Court records show that on the afternoon of June 23, 2000, "Loden was discovered lying by the side of a road with the words `I'm sorry' carved into his chest and apparent self-inflicted lacerations on his wrists."
After pleading guilty in September 2001, Loden told Gray's friends and family during his sentencing: "I hope you may have some sense of justice when you leave here today."
Wanda Farris, Gray's mother, described her daughter as a "happy-go-lucky, always smiling" teenager who aspired to become an elementary school teacher.
"She wasn't perfect, now, mind you," Farris said. "But she strived to do right."
In 2015, attorneys for the Roderick & Solange MacArthur Justice Center sued the Mississippi prison system on behalf of two death row inmates, saying the state's lethal injection protocol is inhumane.
Loden and two other Mississippi death row inmates later joined as plaintiffs.
The Mississippi Department of Corrections revealed in court papers in July 2021 that it had acquired three drugs for its lethal injection protocol: midazolam, which is a sedative; vecuronium bromide, which paralyses the muscles; and potassium chloride, which stops the heart.
Jim Craig, a MacArthur Center attorney, said at a November court hearing that since 2019, only Alabama, Oklahoma, Mississippi and Tennessee have conducted executions using a three-drug protocol.
According to the Death Penalty Information Center, 27 states have the death penalty.
Craig said a majority of death-penalty states and the federal government used a three-drug protocol in 2008, but the federal government and most of those states have since started using one drug.
In November, Alabama Gov. Kay Ivey sought a pause in executions and ordered a "top-to-bottom" review of the state's capital punishment system after a series of failed lethal injections.
A week before Loden's scheduled execution, U.S. District Judge Henry Wingate handed down a ruling saying the execution could happen even while the lawsuit is pending.
He wrote that the US.Supreme Court had upheld a three-drug lethal injection protocol as recently as seven years ago in a case from Oklahoma.
There are 36 inmates on death row in Mississippi. Death Penalty Action, a group opposed to capital punishment, convened a news conference Tuesday in front of the state capitol in Jackson to voice their opposition to Loden's execution.
"Clearly, something in him snapped for him to commit such a horrific crime," said Mitzi Magleby, a spokesperson for the Mississippi chapter of Ignite Justice, an organisation that advocates for criminal justice reform.
"Mr Loden was immediately remorseful. Shouldn't there be room for grace and mercy in such a situation?"
Farris said on Friday that she forgave Loden years ago, but she did not believe his apology.
"I don't particularly want to see somebody die," Farris said. "But I do believe in the death penalty. ... I do believe in justice."
