Davis was convicted on the basis of the statements of that accomplice and a jailhouse tape. Davis' mental age was measured at 9 1/2 and his IQ tested at 73. His mother, Ruby Davis, said: "When Stanley was 2 1/2 he was hit by a car and thrown 15 feet. He didn't say a word for three weeks."

JESSE EDWARD GONZALEZ - Gonzalez, 44, was convicted in the May 1979 shooting death of Sheriff's Deputy Jack Williams in Gonzalez's home in La Puente. Williams and several other officers broke into the home on a drug bust, and Gonzalez shot Williams with a shotgun. According to court records, Gonzalez has "severe learning disabilities" and as a child attended classes for the mentally retarded -- at age 12 he could not read words like cat and this. Gonzalez maintained that he did not know Williams was a police officer, but that claim was refuted by the prosecution's key witness -- a jailhouse informant who was promised leniency on pending charges in exchange for his testimony.
PAUL PALALAUA TUILAEPA - Tuilaepa, 37, was convicted of killing Melvin Whiddon and shooting three others during a barroom robbery in Long Beach in October of 1986. His IQ, according to court records, is in the "low 70s." A police account of the arrest says that an accomplice, David Laupua, "immediately and spontaneously stated: 'I killed the guy. Let my friend go.'" Tuilaepa's attorney, Ron Slick, had eight clients sentenced to death and was known in some legal circles as "Dr. Death." The guilt phase of Tuilaepa's trial lasted three and a half hours -- the defense presented no evidence. For the penalty phase, Slick put on only three witnesses -- testimony lasted just over three hours.
ANDERSON HAWTHORNE JR. - Hawthorne, 42, was convicted of the shooting deaths of two rival gang members, 19-year-olds Jimmy Mamon and Kirk Thomas, in the parking lot of a South-Central Los Angeles video arcade in December of 1982. Another gang member has repeatedly confessed to family and friends that he committed the crime. Hawthorne, known as "Pee Wee" for his diminutive size, scored 86 and 74 on separate IQ tests administered when he was a child. On two more-recent tests, his IQ has been measured at 71 and 75. In anticipation of last week's U.S. Supreme Court ruling, Hawthorne's attorneys filed a federal petition asking that their client be spared the death penalty based on his mental retardation.
MELVIN TURNER - Turner, 45, was convicted of robbing and shooting to death 35-year-old surgeon George S. Hill Jr. and 44-year-old schoolteacher Jo Ella Champion in an airport hangar in July 1979. In 1986 the court reversed the death-penalty conviction, saying that all three prospective black jurors had been improperly removed from the jury trying the case, a "patent violation" of a defendant's right to a trial by a jury of his peers. Turner, who scored 79 on an IQ test, was retried and again convicted of the murders and sentenced to death. His accomplice, Teague Hampton Scott, was convicted of first-degree murder and sentenced to 52 years.
