Details: In 1991, Daniel and Karen Pelletiere moved from New York to Boca Raton, Florida, with their young son, William. Nine months later, Karen began to change, becoming forgetful and distracted. In August of 1992, Daniel claimed that Karen's behavior became violent. Karen was diagnosed with viral encephalitis, a brain infection that can induce delusions and violent behavior, usually causing brain damage. Karen spent four months in the hospital, and after her relatives visited from New York, she began to improve physically but her mental health was still uncertain. When Karen returned from the hospital, she was happy to see her son and their life appeared to be back to normal. However, Daniel noticed that Karen's mental state began to deteriorate again; she began to want to see her mother and sister, even in the middle of the night. Karen left to visit her mother in New York, and Daniel feared that she would not return. Daniel filed for divorce, and on March 19, 1993, was awarded temporary sole custody. David wasn't aware that Karen returned to Florida a week earlier, but when she tried to get custody of William, she was refused because of David's court order. Two days later, Karen received a court order from a judge who was unaware of the other one. That night, while David was at work, his parents were watching William when police arrived with the court order and took him to Karen. Karen fled with William to New York and they have not been seen since.
