Texas Death row inmate Anthony Allen Shore, 55, who became known as Houston's "Tourniquet Killer" because of the signature murder technique he used on four female victims, received a lethal injection just after 6 p.m. Thursday in Huntsville.
Anthony Allen Shores, 55, who admitted to killing a woman and three girls in the 1980s and '90s, was executed by lethal injection, the Texas Department of Criminal Justice said.
Shore disclosed that a fellow prisoner on Texas' death row tried to get him to take responsibility for his crime, Montgomery County District Attorney Brett Ligon said at the time.
Shores received his nickname because of his method of using handmade tourniquets to torture and murder his victims, KTRK reported. "There is no others", he said in his last statement.
The day before Shore's execution, Nunnally said he thought he had done everything he could for Shore. To the family of my victims, I wish I could undo that past. Shore said he would die with a "clear conscience" and he had made his "peace". Maria del Carmen Estrada was one of four females Shore confessed to killing.
When the DNA was tested against cold case files, it proved a positive match in at least one case.
The execution was the first of the year in Texas.
Shore, who died 13 minutes after falling unconscious, was convicted in 2004 and sentenced to death.
Shore's lawyers argued in initial appeals that he suffered brain damage early in life that went undiscovered by his trial attorneys.
He was arrested for the murder in 2003, five years after he was placed on probation and required to register as a sex offender for sexually assaulting two relatives.
The murderer had initially been scheduled to be put to death October, but his execution was postponed for an investigation by prosecutors.
Ligon said that after Shore talked to Texas Rangers and his office, investigators were convinced that Shore was not responsible for Trotter's death or any other open murder cases.
In 2017, 23 convicted murderers were put to death in the US, with seven executions performed in Texas. He is the first inmate to be executed in the U.S. this year.
