Fannie Bates of Oklahoma City holds a sign urging Gov. Mary Fallin to issue a stay in the execution of two inmates, during a protest Tuesday, April 29, 2014, near the Governor's Mansion in Oklahoma City. A botched execution that used a new drug combination left an Oklahoma inmate writhing and clenching his teeth on the gurney later Tuesday, leading prison officials to halt the proceedings before the inmate's eventual death from a heart attack.
