HUNTSVILLE — A North Texas man was executed Tuesday for the 1998 torture-slaying of a 19-year-old mentally challenged woman exactly 13 years ago.
Michael Wayne Hall, 31, received lethal injection less than an hour after the U.S. Supreme Court refused to stop his punishment for the abduction and murder of Amy Robinson. Hall was pronounced dead at 6:23 p.m. at the Huntsville Unit of the Texas Department of Criminal Justice.
The second man convicted in her death, Robert Neville, was put to death five years ago.
Lawyers for Hall argued that he was mentally impaired and ineligible for the death penalty under a Supreme Court ruling that bars capital punishment for those with an IQ under 70.
"Mr. Hall's history of mental retardation reaches back to his childhood," attorney Bryce Benjet said earlier Tuesday.
In appeals, Benjet questioned an assessment from one mental health expert who shifted from an earlier finding and said Hall was not mentally impaired. Three others who examined Hall said he was impaired.
Hall's lawyers went to the Supreme Court a day after the Texas Court of Criminal Appeals — the state's highest criminal court — refused to stop the punishment. Similar appeals also failed in other courts.
