On January 26, 1996, du Pont shot and killed Dave Schultz in the driveway of Schultz's home on du Pont's estate that was located in
Newtown Square, Pennsylvania. The building has since been demolished. Schultz's wife Nancy and du Pont's head of security Patrick Goodale, who was a former
U.S. Marine officer, were present and witnessed the shooting. The security chief was sitting in the passenger seat of du Pont's car when du Pont fired three bullets into Schultz. Police did not establish a motive. Schultz had worked with du Pont to coach the wrestling team for years. Du Pont's friends said the shooting was uncharacteristic. Joy Hansen Leutner, a triathlete from
Hermosa Beach, California, lived for two years on the estate. Leutner said du Pont helped her through a stressful period in the mid-1980s. She later said, "With my family and friends, John gave me a new lease on life. He gave more than money; he gave himself emotionally." She expressed incredulity about the killing. She is quoted as saying, "There's no way John in his right mind would have killed Dave." Many people had noticed du Pont's increasingly disruptive behavior in the months before the murder. During the trial, one of the defense's expert
psychiatric witnesses described du Pont as a
paranoid schizophrenic who believed Schultz was part of an international conspiracy to kill him. He said du Pont believed people would break into his house and kill him, and that he had installed a variety of security features in his house. In Pennsylvania, third-degree murder is a lesser charge than first-degree (intentional) or second-degree (a killing occurring during the perpetration of a felony), and indicates a lack of intent to kill. In Pennsylvania criminal code, "insanity" applies to someone whose "disease or defect" leaves him unable either to understand that his conduct is wrong or to conform it to the law (the
M'Naghten Rule). The jury verdict of "guilty but mentally ill" meant sentencing would be referred to the judge, Patricia Jenkins. She could have sentenced du Pont to 5 to 40 years. He was sentenced to 13 to 30 years' incarceration and was housed at the
State Correctional Institution – Mercer, a minimum-security institution in the Pennsylvania prison system. Du Pont was initially confined to
Cresson Correctional Institute. Du Pont's attorneys filed appeals in the criminal case. In 2000, his case reached the
U.S. Supreme Court, which upheld the verdict. Du Pont was first eligible for parole on January 29, 2009; it was denied. In 2010, the
United States Court of Appeal for the Third Circuit in Philadelphia rejected all but one issue raised on appeal (involving his use of prescribed
scopolamine before he killed Schultz), and requested written briefs. Du Pont's maximum sentence would have ended on January 29, 2026, when he would have been 87. ==Death==
