es Leonard had just made a game-winning layup in overtime, ensuring
an undefeated 20-0 season for his high school basketball team. Moments later, the 16-year-old junior collapsed on the gym floor, and the overjoyed shouts of the home crowd at Fennville High School in Michigan quickly turned to stunned horror. He died a short time later at an area hospital. An autopsy report confirmed the cause of death as cardiac arrest due to an enlarged heart. Leonard’s devastating story made national news because of how and where he died, but that same weekend in March 2011, at least four other high school athletes in towns across the country also died of the same cause.
