The U.S. Supreme Court blocked the execution of Ruben Gutierrez about an hour before he was scheduled for death for the murder of a Brownsville woman, Escolastica Harrison.

Harrison’s sister, Estella Cuellar-Perez, spoke to KRGV on Tuesday hours before the convicted murderer was set to die. The family is now devastated by the high court’s decision.
