The Latest on the execution of Houston's "Tourniquet Killer" (all times local):

6:40 p.m.

A man who became known as Houston's "Tourniquet Killer" because of his signature murder technique has become the nation's first prisoner executed in 2018.

Anthony Allen Shore received lethal injection Thursday evening in Texas for the 1992 strangling of a 21-year-old woman whose body was dumped in the drive-thru of a Houston Dairy Queen. Maria del Carmen Estrada was one of four females Shore confessed to killing.

The 55-year-old Shore's execution originally was set for last October but was delayed for an investigation after another condemned inmate concocted a scheme to have Shore take responsibility for the other inmate's murder case.

Shore confessed to four slayings after a tiny particle collected from under Estrada's fingernail was matched to his DNA. Estrada's murder had gone unsolved for more than a decade.

A man who became known as Houston's "Tourniquet Killer" because of his signature murder technique on four female victims is set to become the nation's first prisoner executed in 2018.

Texas prison officials Thursday evening are scheduled to give 55-year-old Anthony Allen Shore lethal injection for the 1992 strangling of a 21-year-old woman whose body was dumped in the drive-thru of a Dairy Queen in Houston.

In 1998, Shore received eight years' probation and became a registered sex offender for sexually assaulting two relatives. Five years later, he was arrested for the 1992 slaying of Maria del Carmen Estrada after a tiny particle recovered from under her fingernail was matched to his DNA.

He also confessed to killing a 9-year-old and two teenagers.
