On Wednesday, Texas plans to execute a man convicted of opening fire at a children’s birthday party in 2008, believing a rival gang member was present and fatally shooting a woman and her five-year-old granddaughter. Texas plans to put Erick Davila to death by lethal injection at its execution chamber in Huntsville. If the execution goes ahead, it will be the ninth this year in the United States and the 550th in Texas since the U.S. Supreme Court reinstated the death penalty in 1976.
