The 14-year-old was murdered in 2011 when she interrupted a burglary at her home.
Despite the rain Saturday, the community came together to raise money in her name.
Kelli's dad was on eyewitness news Saturday morning and said he and his wife made a choice after Kelli's death.
"We wouldn't be here today without the support of the community," said John O'Laughlin. "I think we might still be hiding in my office in our house because the community really dragged us out of the house and as you say wrapped their arms around us."
The man charged with Kelli's murder has still not gone on trial.
