Suspect in Case of Missing NYC Boy Due in Court The defense of a man charged with killing a 6-year-old boy in 1979 will revolve around his mental state and a false confession to the crime, but he is not pursuing an insanity defense in the sensational case, his attorney said. Pedro Hernandez, 51, was scheduled to appear in court Wednesday for an arraignment on the murder charge in the death of Etan Patz, who disappeared on his way to a school bus stop more than three decades ago. Hernandez was expected to plead not guilty and he isn't pursuing an insanity defense, said his lawyer, Harvey Fishbein. An insanity defense would mean acknowledging he committed the crime but arguing that he was too psychologically ill to know it was wrong. But Hernandez will maintain he didn't kill Etan and argue he made a false confession because of his mental problems, among other factors, Fishbein said. "The only part that mental disease plays in this case is its role in the confession," he said before the court date. Psychiatric exams of the jailed Hernandez have found that he has an IQ in the borderline-to-mild mental retardation range, his lawyer has said. Hernandez also has been found to suffer from schizotypal personality disorder, which is characterized by hallucinations, according to his lawyer. Etan's disappearance led to an intensive search and spawned a movement to publicize cases of missing children. His photo was among the first put on milk cartons, and his case turned May 25 into National Missing Children's Day. Hernandez was a teenage stock clerk at a convenience store when Etan disappeared on his way to school on May 25, 1979. He was never questioned despite the exhaustive search and left the city for New Jersey shortly after the boy vanished, police said. He was approached this spring based on a tip that came after federal authorities dug up a basement in the neighborhood hoping for clues, putting the cold case back into the limelight once again. Hernandez is a married father of two with no criminal record and was living in Maple Shade, N.J. Investigators say Hernandez told them he lured the boy into the convenience store with the promise of a soda. According to police, he said he led the child to the basement, choked him and left his body in a bag of trash about a block away. Following the arrest, court hearings for Hernandez were postponed for weeks, with both sides saying they were continuing to investigate. Authorities seized a computer and a piece of old-looking children's clothing from Hernandez's home, scoured the basement of the building where he had worked in what was then a grocery store and interviewed his relatives and friends - but nothing incriminating came of it, according to a person familiar with the investigation. The person wasn't authorized to discuss findings not yet made public and spoke to The Associated Press on condition of anonymity. Under New York state law, a confession can be enough to convict someone as long as authorities can establish that a crime occurred. The boy's body has never been found. Etan's parents, Stan and Julie Patz, have been reluctant to move or even change their phone number in case their son tried to reach out. They have not commented on the recent developments. Etan was declared legally dead by his father more than a decade ago so he could sue convicted child molester Jose Ramos in the boy's death. Ramos was found responsible, but it's unclear how that finding could now factor into the prosecution of Hernandez.
