Around 50 balloons were released.
"We write messages on a piece of note card and we put them on the balloon and then we let them go and these messages will get to Austin," said a participant.
Austin was killed on May 13th while waiting at a bus stop on this way to school.
Family and friends reflected on the type of person he was.
"An amazing helper to his mom and church, family and was an incredible Boy Scout, just earned his Eagle Scout, just an amazing kid and a very sad loss for this world," said Kim Hadley.
Grace Hadley went to middle and high school with Austin and they occasionally carpooled.
"I just think he was a great person and someone I aspire to be like, like everyday I try to do things that he was able to do in just his short time. It's incredible to see who he became in just 16 years," she said.
Neighbor Susan Dunnigan watched Austin grow up for 11 years. She says he was very humble and helpful.
"Always perfectly complacent, in a way that I found really quite remarkable."
He left an impact on many and won't soon be forgotten.
"He will just be so missed.. that's all there is to it," added Dunnigan.
So many people attended the funeral that a smaller service was held in a separate building on the church campus.
