Milton Mathis, Convicted Killer, Executed In Texas Despite Evidence Of Retardation zainyk: A man convicted of slaying two people and critically injuring a third in a drug house shooting was executed on Tuesday evening by Texas officials, despite evidence that he suffered from mental retardation. Milton Mathis, 32, was sentenced to death in 1999, three years before the U.S. Supreme Court ruled that execution of the mentally retarded violated the Constitution’s prohibition on cruel and unusual punishment. Intelligence tests, including one given by the Texas Department of Corrections in 2000, measured Mathis’s IQ in the low 60s, well below the threshold for mild mental retardation as recognized by almost all states. The argument used by the prosecution is that he was “street smart”, it’s a argument I have heard DA’s use about clients I have worked with during my time in NC. To be clear, the man had an IQ in the low 60’s, this gives him a mental age of 8-10. According to court records, Mathis began smoking PCP and marijuana soaked in formaldehyde, known as “fry,” as early as age 12. There is no excuse for what Milton Mathis did. He was convicted of murder. But what purpose is served, what good is it to society, other than vengeance, when you kill a man with the mind of a 10 year old. He was killed by the state, with the sanction of the people. His mind was that of a child, could he have not been locked away for life, as punishment? Could he not have been allowed to live yet deprived of his freedom as a result of what he did? What difference would it have really made to the people and to the state? I thought that the Supreme Court had ruled that it was unconstitutional to do executions of people with MR.
