Low IQ score focus of Texas death row appeal

HUNTSVILLE, Texas (AP) — Death row inmate Marvin Wilson spent his school years in special education classes, got failing or near failing grades and several times received “social promotions” to the next grade level until he finally quit school in the 10th grade.

Wilson’s lawyers have asked the U.S. Supreme Court to overrule state and lower federal courts that questioned the validity of a psychological test that pegged his IQ at 61, below the threshold of 70 that would suggest he’s mentally impaired and thus, ineligible for capital punishment.
