LOUISVILLE - A Kentucky high school football coach charged in the death of a player who collapsed at practice says he is heartbroken and that part of his life has been taken away.  "The one thing people can't forget in this whole situation is that I lost one of my boys that day. A boy that I loved and a boy that I cared for and a boy that meant the world to me," coach David Jason Stinson told dozens of supporters at his home Saturday night. "That's the thing that people forget and don't ever forget that. That's a burden I will carry with me for the rest of my life."  It was his first public remarks since he was charged with reckless homicide Thursday in the death of 15-year-old Max Gilpin, a sophomore offensive lineman who died three days after collapsing during a sweltering practice in Aug. 20.  Heat exposure deaths have occurred occasionally in all levels of football and the cases have led to numerous lawsuits. However, it appears a coach has never been criminally charged in the deaths.
