HUNTSVILLE, Texas — Attorneys for a convicted killer facing execution want the U.S. Supreme Court to stop this week's scheduled punishment.

Lawyers for 54-year-old Marvin Wilson are asking the high court to reverse rulings from other courts that have refused to halt the execution despite a psychological test that put Wilson's IQ at 61. That's a score they insist indicates mental impairment and makes Wilson ineligible for execution Tuesday evening in Huntsville for killing a police informant in Beaumont 20 years ago.

State lawyers argue the result from a 2004 test is faulty and that all other tests showed his IQ above the impairment threshold of 70.

Wilson was condemned for the shooting death of 21-year-old Jerry Williams. Williams provided information that led to Wilson's drug arrest a week earlier in 1992.
