This is Crime House in court, experts debated whether a sleepwalking defense could acquit Scott Flater in the brutal murder of his wife Yarmila.

This episode discusses an active criminal case. The information we share is based on what's publicly available at the time of recording and may change as new evidence comes to light. We aim to inform, not to decide guilt or innocence. So everyone mentioned is presumed innocent until proven guilty in a court of law. On the night of January 16, 1997, investigators arrested 43 year old Scott Flater after his wife Yarmila was discovered dead in the family's pool and had sustained dozens of stab wounds. But Scott claimed that he had no recollection of anything that happened that night. The case moved into a Maricopa county courtroom where prosecutors laid out bloody physical evidence and eyewitness testimony from a neighbor who said he watched Scott commit the crime from his upstairs bedroom window. But the defense introduced a shocking explanation. They admitted that Scott killed his wife, but argued that the only reason he did it was because he had a violent sleepwalking episode. This argument set the stage for one of the most controversial murder trials of the decade. In the spring of 1999, a war of the experts broke out in the courtroom. During Scott's trial, the prosecution's experts argued his actions were too complex for him to have been asleep when he killed his wife. They pointed to the sheer sequence of actions. He stabbed her repeatedly, controlled the physical struggle, moved the body, held her head under cold water, stashed the evidence and changed into clean clothes. They argued that these behaviors required sustained awareness, coordination and decision making that went Far beyond what is seen in sleepwalking episodes. But the defense experts argued that Scott's behavior was completely in line with known sleepwalking tendencies and that Scott was exhibiting behaviors that fit his routine. They argued that he fell asleep and then sleepwalked downstairs to go fix the pool like he had tried earlier and before. He had also brought his hunting knife to try and fix it. Their kids also said that he would keep his yard work clothes in the same bin in the garage that he had put them in. After the murder, Scott's lawyers realized that it was less about the actual actions of sleepwalkers and more about proving if he was actually asleep when he killed Yarmila. So they called neuroscientist and professor Dr. Rosalind Cartwright to the stand, who explained that sleepwalkers possess a genetic defect in the brain that affects the transition from deep sleep into dreaming sleep. Apparently, both of Scott's children were known to possess this trait. This meant his sleepwalking wasn't just habitual. It was genetic. Tonight, we're covering part three of our deep dive on the sleepwalker murder against most defense attorneys, advice. Scott fader decided to testify in his own trial and take control of his own narrative. For nearly a month, everyone picked apart his credibility and his brain, and it was finally his turn to speak. By choosing to testify, Scott took an enormous risk. Defendants rarely testify in their own murder trials because every expression, every answer, and any hint of anger will be used against them. But after weeks of experts dissecting his mind, Scott said he felt like he had no choice but to tell his story himself. Scott addressed the court on June 16, 1999. He wore a dark suit and glasses and appeared pale and worn out. He was put on the stand to defend himself for nearly two hours. He began by saying he understood the jury's dilemma. He said that initially he even questioned the sleepwalking defense. He kept thinking that yarmoula perhaps died as a result of a burglary gone wrong. But he also believed his neighbor would not lie about something this serious. Which is why he volunteered to undergo something called a polysomnogram, Also known as a sleep study. The test measured Scott's brain waves and muscle action over four nights of sleep. And it was his way of proving to himself whether he had really killed Yarmoula in his sleep. Scott's test results showed reduced slow wave activity, which meant his brain wasn't getting as much deep sleep as it should. At the time of Yarmila's death, he was losing sleep because of his stress at work. This lack of deep sleep made his brain more unstable at night and more likely to slip into a sleepwalking episode. Scott told the jury that it wasn't until he got those test results that he finally believed he had killed his own wife in his sleep. Jurors listened quietly as he spoke. His testimony wasn't treated as a confession, but it wasn't ignored either. But the science he relied on still had limits. The sleep study couldn't recreate the night Yarmila died. It could only suggest a vulnerability, not prove what Scott was doing in those final moments. In addition to his sleep study results, he said he had been diagnosed with something known as non insane automatism, a state of sleep in which a person has no control over his or her actions. He also had a long, proven history of sleepwalking that everyone in his life was aware of. Between his personal history with sleepwalking and the signs backing it up, he said it was like he woke up and saw the truth of what happened to his wife. In the end, none of that mattered to him. All the scientific jargon and diagnosis were beside the point. He expressed his utter devastation at the loss of his wife and said her murder would haunt him forever. He loved Yarmila more than anything and didn't know what to do without her. His eyes were filled with tears as he described dreaming of her every night. He hurt for his children too, who believed him, but would still have to grow up without a mother and possibly without a father. As he spoke, Scott looked at his children from the stand. He begged the judge and the jury to let him reunite with them. After Scott delivered his emotional testimony, it was time for the jurors to decide his fate.
