The Supreme Court denied his request for a stay of execution less than two hours before his lethal injection began.
Lead defense attorney Lee Kovarsky said he was "gravely disappointed and saddened" by the ruling, calling it "outrageous that the state of Texas continues to utilize unscientific guidelines ... to determine which citizens with intellectual disability are exempt from execution."
Wilson was convicted of murdering 21-year-old Jerry Williams in November 1992, several days after police seized 24 grams of cocaine from Wilson's apartment and arrested him.
Witnesses testified that Wilson and another man, Andrew Lewis, beat Williams outside of a convenience store in Beaumont, about 80 miles east of Houston. Wilson, who was free on bond, accused Williams of snitching on him about the drugs, they said.
Witnesses said Wilson and Lewis abducted Williams, and neighborhood residents said they heard a gunshot a short time later. Williams was found dead on the side of a road the next day, wearing only socks, severely beaten and shot in the head and neck at close range.
Wilson was arrested the next day when he reported to his parole officer on a robbery conviction for which he served less than four years of a 20-year prison sentence. It was the second time he had been sent to prison for robbery.
At Wilson's capital murder trial, Lewis' wife testified that Wilson confessed to the killing in front of her, her husband and his own wife.
Lewis received a life prison term for his involvement.
In Wilson's Supreme Court appeal, Kovarsky said Wilson's language and math skills "never progressed beyond an elementary school level," that he reads and writes below a second-grade level and that he was unable to manage his finances, pay bills or hold down a job.
