Georgia high school mourns 17-year-old 'golf team leader' who died suddenly

Smith added that Kelly's body was sent for an autopsy to determine his cause of death.

"Hadden was an outgoing kid, and he never met a stranger," Smith told the station. 

"Hadden LOVED golf and the Golf Team surely loves Hadden," the post read. "Hadden was our team leader, always encouraging and forever speaking positive words to all around him. He so hoped that our golf team would keep improving and desperately sought after participating in the State tournament. 

"He was our top performing golfer and always finished earlier than most of his teammates. He ALWAYS stayed till each team member finished. He could have left as most of the time he finished first against the competition. It wasn't about him. He stayed to support his team. He wanted the team to succeed! 

"What a witness to his character! We love Hadden and we love his family! Our thoughts and prayers go out to the family. Let's take this example of selflessness into our own lives and little by little make the world a better place!

Smith also spoke about Kelly's love for the game of golf. 

"He played every day, and I believe if that were something he wanted to do, he would have gone pro because he was that good."

"There are no words to express the sadness that our DCHS family feels for the loss of junior Hadden Kelly. Please join us in prayer for his family, friends, and our DCHS Family. ''Gone from our sight, but never from our hearts."
