Could IQ Score Could Halt Texas Execution?

Update: Wilson was executed. The lower courts agreed with state lawyers that the results of the IQ test were faulty. The Supreme Court denied the request to stop the execution. Wilson was the seventh prisoner executed in Texas so far this year.

Earlier: Attorneys for a Texas man scheduled to die Tuesday evening are asking the U.S. Supreme Court to stop the execution.

Marvin Wilson, 54, was convicted for the 1992 abduction and shooting death of a police informant – 21-year-old Jerry Williams – in Beaumont.

A psychological test found Wilson’s IQ was 61 – which defense lawyers say indicates mental impairment and makes him ineligible for execution. State lawyers argue that the test result was faulty and that all other tests showed his IQ above the impairment threshold of 70.

Wilson did not finish high school and worked in construction. He also served time for robbery.

If the execution is carried out, Wilson would be the second person in Texas put to death with a single-drug injection.
