The Tennessee Supreme Court ruled 4-1 yesterday that a condemned child murderer and rapist is mentally competent for execution, which would be Tennessee’s first since 1960. Robert Glen Coe is scheduled to die March 23. Last week Coe’s attorneys argued before the Supreme Court that the states process for determining mental competency is flawed and that Coe was denied his constitutional rights during a January competency hearing. The justices ruled Coe got a fair hearing and that he has the mental capacity to understand his impending execution and reason for it.
