The U.S. was preparing to carry out two executions on Thursday, one in Oklahoma and one in Texas. In Texas, the condemned man is John Allen Rubio, 46, who is set to be put to death at the state prison in Huntsville. He was convicted of beheading three young children he was raising in a 2003 killing that rattled a community along the U.S.-Mexico border. The other man facing execution is James Pavatt, 73, who is set to die by lethal injection at Oklahoma's state penitentiary in McAlester.
