A Texas man convicted in the shooting death of a 21-year-old man in 1992 was executed Tuesday in Huntsville, officials said.
Marvin Wilson was pronounced dead at 6:27 p.m. (7:27 p.m. ET), the Texas Department of Criminal Justice said.
Wilson’s IQ had been measured at 61, according to the American Civil Liberties Union of Texas, which opposed the execution.
In an online posting, the ACLU said Wilson, 54, had been declared “intellectually disabled” by a court-appointed neuropsychologist.
