HOUSTON --The Texas Court of Criminal Appeals has rejected an appeal from a man from El Salvador sent to Texas death row for the slayings of two women in Houston nine years ago. Walter Alexander Sorto contended he was mentally impaired, making him ineligible for execution under a U.S. Supreme Court ruling. The Texas court said Wednesday he failed to provide enough evidence to support his claim. The 33-year-old Sorto is one of two men condemned for the abduction, rape and fatal shootings of 24-year-old Roxana Capulin and 38-year-old Maria Rangel. The women were waitresses at a restaurant in what's known as Houston's East End. Prosecutors said Sorto was on probation at the time of the killings and was responsible for at least two other murders.
