Billy Koch won a bronze medal for the United States at the 1996 Olympics in Atlanta. Koch, his wife and their children have been suffering from a condition, called Morgellons disease by those who believe it to be a true condition but generally thought among the medical community to be a type of delusional parasitosis, which can cause sufferers to experience what they perceive as a crawling feeling and an expulsion of filaments from under the skin. This condition is what many people feel led to his demise in the major leagues.
