The state of Nebraska is scheduled to carry out its first execution in more than 20 years today. Carey Dean Moore is set to be killed using a three-drug cocktail that includes fentanyl, which has never been used before in an execution. On Friday, a federal judge rejected a move by a German pharmaceutical company to block the killing. More than 60,000 opponents of the death penalty have also signed a petition urging Nebraska’s governor to call off the execution.
