was part of the estate of du Pont. According to du Pont's will—unsuccessfully challenged by several parties—80 percent of the sale proceeds went to the family of Bulgarian wrestler Valentin Jordanov Dimitrov and 20 percent to the Eurasian Pacific Wildlife Foundation, based in Paoli, Pennsylvania, a group du Pont founded to support Pacific wildlife. In 1986, competing as "John Foxbridge", he won the Grand Prix d'Honneur in the FIP Championship Class at the STOCKHOLMIA 86 international stamp exhibition for his display of "British North America". While du Pont continued to buy stamps while in prison, he was not allowed to bring them there. Athletics Du Pont developed the Liseter Hall Farm in Newtown Square as a high-quality wrestling facility for amateur wrestlers. He called the private group "Team Foxcatcher," after his father's noted racing stable. Du Pont established an Olympic swimming and wrestling training center and sponsored competitive events at the estate. He also allowed some people, such as Olympic champion wrestlers Mark Schultz and later his older brother Dave Schultz and his wife, to live in houses on the grounds for years. Dave Schultz also coached the Foxcatcher team. Du Pont became a sponsor in wrestling, swimming, track, and the modern pentathlon. He was also involved in promoting a subset of the modern pentathlon (run, swim, shoot) as a separate event. He took up athletics and became a competitive wrestler in his 50s. His only prior wrestling experience was as a freshman in high school. He began competing again at the age of 55 in the 1992 Veteran's World Championships in Cali, Colombia; following that in 1993 in Toronto, Ontario; and in 1995 in Sofia, Bulgaria. Lawsuit In August 1988, a problem-plagued wrestling program he funded at Villanova was shut down after just two years. In December 1988, a lawsuit (which was settled out of court) claimed du Pont had made improper sexual advances to Villanova assistant coach Andre Metzger. Murder of Dave Schultz 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 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
