Wright said that Penry's IQ was between 50 and 60; an IQ of 70 is used as the threshold for intellectual impairment. Prosecutors remained convinced that Penry was not intellectually impaired, pointing to two television interview clips that had been shown at one of his trials. Prosecutor William Hon said that Penry spoke normally on one tape but "like Elmer Fudd" on the other. "It was the most contrived performance you've ever seen in your life," Hon said. He said that Penry was a sociopath and that he had only been sent to a home for the intellectually disabled because he had been such an uncontrollable child.
