Forty-seven-year-old Larry Godfrey's death will be considered a natural death. He was diabetic and was on medication, which led to cardiovascular collapse. But Gregory said that heat was a factor in Godfrey's death.
The Sumner County Sheriff's Department says Godfrey's body was found on Saturday near Oxford, lying near his bicycle.
Family members said Godfrey was training for a bicycle race to raise funds for multiple sclerosis research.
