Hundreds came to honor the life of the International Baccalaureate student.Band mates shared with the crowd how Gavin made an impact on them."I wasn't even a freshman yet and didn't know how to play my instrument, but he instantly met me with kindness and a hint of humor," said one student. That's the leadership Mack also remembered. "He never made me feel like I was doing something wrong because since he was drum major, his job was to lead and correct," Mack said. "When he corrected people, he would correct his own mistakes. He was just a good person."

"I thank God every day I can't see you, I thank God that I was able to meet a wonderful person like you."The band will now offer an award in Gavins name so his legacy lives on.
