The U.S. Supreme has refused to review an appeal from a 48-year-old Salvadoran man on Texas death row for the slayings of two Houston store clerks during an attempted robbery more than 17 years ago.
The high court had no comment in its decision Monday in the case of Gilmar Guevara.
Attorneys for Guevara asked the justices to reverse lower courts' rulings rejecting arguments that he's mentally impaired and ineligible for the death penalty.
The latest news from around North Texas.
Guevara was convicted and sentenced to death for the fatal shootings of 48-year-old Tae Youk and 21-year-old Gerardo Yaxon. Youk was from South Korea and Yaxon from Guatemala.
Guevara, identified as the shooter, and two accomplices fled the scene in southwest Houston in June 2000 without any money.
He does not yet have an execution date.
