A Tennessee inmate is scheduled to die in the state’s electric chair Thursday, becoming the fifth convict in the past 16 months to choose electrocution over lethal injection, the state’s preferred method. Nicholas Sutton, 58, was sentenced to death in 1986 for killing fellow inmate Carl Estep in a conflict over a drug deal while both were incarcerated in an East Tennessee prison. In a clemency petition to Tennessee Gov. Bill Lee, Sutton’s supporters said he is not the same man who went to prison 40 years ago.
