HOUSTON (AP) — The U.S. Supreme Court has refused to review the case of a 44-year-old Mexican national set to die next week for the beating death of a man who employed him at his Kerrville-area ranch.

Attorneys for Ramiro Hernandez contended he was mentally impaired and ineligible for execution for the 1997 slaying of 48-year-old Glen Lich.

Hernandez, from Tamaulipas, Mexico, also argued he had deficient legal help at his trial, contending evidence of a previous murder conviction and prison term in Mexico was improperly allowed.

He's set for lethal injection April 9. In a related case, his attorneys are arguing in state courts the Texas prison system should be forced to identify a new source of pentobarbital used to execute him. Texas prison officials want the provider's name kept secret.
