HUNTSVILLE, Texas - Texas prison officials have executed a registered sex offender for the rape, robbery and slaying of a woman abducted from a San Antonio bus stop 11 years ago.

Ramon Torres Hernandez was one of three people convicted in the killing of 37-year-old Rosa Maria Rosado. She was pulled into a car Hernandez was driving after she refused to let go of her purse during a drive-by robbery.

The 41-year-old Hernandez was on parole at the time of his arrest in Rosado's death. He also was a suspect in the slayings of three teenagers and a 12-year-old girl.

The U.S. Supreme Court refused last month to review Hernandez's death sentence. A late appeal in the state courts was rejected several hours before the Wednesday evening lethal injection.
