"I want to say I'm OK, but I'm not OK because the best thing in my life has been taken away from me," said Tyler King, Chelsea's younger brother.
Thousands of teachers, classmates and neighbors filled a high school stadium, as family and friends told the crowd of Chelsea's big dreams, terrific sense of humor, sense of style, athleticism and thirst for knowledge.
Chelsea's family was profusely thankful for the massive search for her after she went missing Feb. 25 on a run at a San Diego park, as well as for the outpouring of sympathy after her body was found five days later.
Speakers said Chelsea's heinous death galvanized people to prevent other children from falling victim to predators. A moment of silence was held for Amber Dubois, whose bones were found a last week north of San Diego more than a year after she went missing while walking to school.
"I will channel my rage and commit to spending my life to making our society safe from the incurable evil," he said to applause. "Known sexual predators are not curable ... If anyone - anyone - believes that this evil is treatable, let them live next door to you and your children, not ours."
John Gardner, 30, has pleaded not guilty to Chelsea's murder and attempted rape of another woman in December. He is also a suspect but has not been charged in the killing of Amber Dubois.Gardner served five years of a six-year sentence for molesting a 13-year-old neighbor in 2000. He was on parole for three years, until September 2008.
Brent King, Chelsea's father, said his daughter's attacker would have picked another victim if she had chosen another park to go running on the afternoon she vanished.
Kelly King, Chelsea's mother, said she draws inspiration by imagining a conversation in which her daughter urges her to stay focused on "very important things to do." She acknowledged Amber Dubois' parents, who attended the ceremony.
"We, as parents, have been thrown into a club no one wishes to be a part of," she said.
