HUNTSVILLE, Texas (AP) - A Mexican citizen on death row in Texas has been executed for the slaying of his 16-year-old cousin.
Ruben Ramirez Cardenas was given a lethal injection Wednesday night after several federal court appeals failed to halt his punishment for the February 1997 killing of Mayra Laguna.
She was abducted from her family's McAllen apartment and fatally beaten. Her body was later dumped in a canal in the Rio Grande Valley in far South Texas.
Appeals for the 47-year-old Cardenas focused primarily on efforts to have trial evidence undergo new DNA testing.
In a filing to the U.S. Supreme Court hours before his punishment Wednesday, lawyers argued Texas was violating Cardenas' due process rights and a state statute that covers forensic testing and asked the justices to halt the execution for a court review.
