LOUISVILLE, Ky. — A former Kentucky high school football coach was found not guilty yesterday in the death of a player who collapsed at a practice where the team was put through a series of sprints on a hot summer day.

Attorneys said the case was the first time a football coach was charged in the death of a player.

Former Pleasure Ridge Park High School coach David Jason Stinson, 37, was charged after 15-year-old Max Gilpin collapsed at an August 2008 practice as the team ran a series of sprints known as "gassers." He died three days later at a Louisville hospital of heat stroke, sepsis and multiple organ failure.

The jury deliberated for about 90 minutes, and Stinson hugged defense attorney Brian Butler after the verdict was read.

"That's why they came back quickly, because he was innocent," said Butler, who characterized the prosecution on charges of reckless homicide and wanton endangerment as a "witch hunt."

During the trial, players said Stinson ordered the gassers as punishment for the lack of effort they showed at practice on a day where the temperature and heat index were both 94 degrees.

Prosecutors relied on a series of Gilpin's teammates who testified that several teens became ill during the gassers, vomiting or bowing out with ailments.

Several experts testified that Gilpin suffered from exertional heat stroke, which led to his death.

Stinson's defense relied on players who testified that they only ran a few more wind sprints than normal that day. Three of Gilpin's classmates, along with his stepmother, testified that Gilpin complained of not feeling well throughout the day he collapsed.

Defense medical experts told jurors that it appeared a combination of heat, the use of the dietary supplement creatine and attention deficit disorder drug Adderall, and being ill were the main factors that contributed to Gilpin's death.
