Mike Parson grants clemency, Amber McLaughlin, 49, will become the first transgender woman executed in the U.S. She is scheduled to die by injection Tuesday for killing a former girlfriend in 2003. There is no known case of a transgender inmate being executed in the U.S. before, according to the anti-execution Death Penalty Information Center. She won the lawsuit in 2018 and became a mentor to other transgender inmates, including McLaughlin. Kevin Johnson, 37, was put to death Nov. 29 for the ambush killing of a Kirkwood, Missouri, police officer. Another Missouri inmate, Leonard Taylor, is scheduled to die Feb. 7 for killing his girlfriend and her three young children.
