expert testimony agreed that Yates was psychotic, Texas law requires that, in order to successfully assert the insanity defense, the defendant must prove that he or she could not discern right from wrong at the time of the crime. In March 2002, a jury rejected the insanity defense and found her guilty. Although the prosecution had sought the death penalty, the jury refused that option. The trial court sentenced her to life imprisonment in the Texas Department of Criminal Justice with eligibility for parole in 40 years.
