Pictured: Nathan Lewis, former Sheriff of Hemphill County, TX. Lewis resigned from his post after being formally reprimanded by the Texas Commission on Law Enforcement (TCOLE) for falsifying training records. Lewis has also been accused–both formally and informally–of numerous other breaches of the law and his ethical duty as a law enforcement officer. At the time of Tom Brown’s disappearance, Lewis was Sheriff of Hemphill County. The year before, Tom’s mother had filed a complaint against Lewis for allegedly harassing her son.
