The Oklahoma State Penitentiary announced the execution of Antony Sanchez, who was convicted of murder at 10:19 local time.

Sanchez, who was convicted of murder, did not apply for clemency, although he continued to maintain that he had nothing to do with Busken's murder.

In a phone call with the Associated Press (AP) before his execution, Sanchez maintained his innocence and claimed that the DNA found was fake and not his.

On the other hand, Oklahoma Attorney General Gentner Drummond noted that DNA evidence conclusively linked Sanchez to Busken's murder.

Incident

Busken was found dead on December 20, 1996, raped and shot in the head after being abducted from the parking lot of the apartment building where she lived.

While the killer was not identified for years, Sanchez gave a DNA sample when he was jailed for burglary in 2002, which changed the course of the case.

Sanchez was sentenced to death in 2006 after a semen sample found on Busken's clothes at the crime scene matched Sanchez's DNA.

Tim Kuykendall, the Cleveland District Attorney at the time of Sanchez's trial, noted that in addition to DNA evidence, there was other evidence linking Sanchez to the murder, including ballistics and a shoe print found at the scene.
