Inmate From Dallas Robert Sparks Executed

A North Texas death row inmate was put to death last night by lethal injection. Robert Sparks was condemned for fatally stabbing his two stepsons and his wife in at their Dallas home in 2007. His lawyers sought to stop his execution with arguments of intellectual disability and a jury tainted by a bailiff wearing a syringe tie. The U.S. Supreme Court rejected his final appeals Wednesday evening.
