HUNTSVILLE, Texas — The U.S. Supreme Court has refused to block the execution of Texas prisoner Rodrigo Hernandez for the abduction, rape and strangulation of a 38-year-old woman in San Antonio 18 years ago.

The high court order Thursday came about two hours before Hernandez was scheduled for lethal injection.

The 38-year-old Hernandez was condemned for killing Susan Verstegen. She was attacked behind a supermarket where she was working. Her body was found dumped in a garbage barrel behind a San Antonio church.

The 1994 slaying went unsolved for eight years until Hernandez, as a requirement for parole from a Michigan prison, submitted a DNA sample that went into a national database. The DNA linked him to her death.

DNA more recently also tied Hernandez to a 1991 slaying in Michigan.
