POWAY - Volunteers handed out sunflowers to an overflow crowd of more than 6,000 mourners arriving at Poway High School today to honor slain teenager Chelsea King, described by her principal as a "shining light" that the community must make sure is never extinguished.

Family, friends, classmates and throngs of others sat beneath her giant image over the football stadium grandstand, as the sun beamed through cloudy skies.

Poway High School Principal Scott Fisher, speaking from a stage festooned with sunflower bouquets, told the crowd the events in the two weeks since Chelsea's disappearance and the discovery of her body have filled the hearts of everyone at the school, and "millions who never had the privilege of knowing Chelsea."

"While we mourn," Fisher said, "Chelsea's passing has strengthened the bonds of this community more than I could have ever imagined."

Today's event was arranged by family as a celebration of Chelsea's life, and the supply of 6,000 tickets for the stadium had been exhausted by 8 a.m., causing the family to request others to watch it online. Coverage was transmitted on the Internet by the San Diego Union-Tribune and local TV stations.

The memorial got under way at 2 p.m. and featured music from the Poway High School band and the San Diego Youth Symphony, of which she had been a member.

King's parents, Brent and Kelly King, and her younger brother Tyler each spoke to those gathered and received a standing ovation.

"I wake up every morning now and I have to remember how to breathe," Kelly King said. "I have to remember how to put one foot in front of the other."

She said Chelsea tells her, "Come on, mom, we have important things to do, very important things to do. I tell her, 'Angel, I don't know how to begin,' and she says, 'Take in all the beauty that surrounds us and help other

people to see it, too.' "

Brent King said that, "When this tragedy began to unfold, I needed to make a choice. I could choose despair, that would have been easiest; or I could choose rage. I have enough of that in me to walk the deepest part of hell a thousand times. Or I could choose hope. Because of you, I chose hope.

"I will channel my rage and commit my life to fight an incurable evil. Known sexual predators are not curable."

The couple flanked son Tyler as he walked to the microphone and said of his sister, "Her spirit is so large, it defeats death."

A montage of videos and photos was shown of King as a baby and as a teenager mugging for the camera and dressing in zany outfits. King's cousin, Stephanie Dorian, called her a "sparkly gem of a girl" and said the teenager's story has touched the world.

"She has not died in vain," Dorian said. "Neither did Amber Dubois. Chelsea and Amber have become the catalyst to a new generation coming together before our very eyes to demand 'No, never again.' "

Dorian asked for a moment of silence in memory of Chelsea and Amber, a 14-year-old Escondido High student who may have fallen victim to the same alleged sexual predator.

A number of King's friends, some who participated with her in band, track and peer counseling, and teachers, described her as enthusiastic, energetic, with a quirky sense of humor and a contagious zeal for life.

At one point, everyone in the audience stood, raised high their sunflowers tied in light-blue ribbons, while the symphony played the swelling hymn, "All is well with my soul."

Pastor Harry Kuehl of the Church of Rancho Bernardo gave a benediction and then led the audience in shouting, "Chelsea, we love you!" He offered the final words, "She heard us."

Volunteers who had handed out sunflowers before the ceremony gave mourners as they left the stadium packets of sunflower seeds inscribed, "With your help, Chelsea's light will never dim."

King, an avid cross-country runner, disappeared Feb. 25 while going for an after-school run in Rancho Bernardo Community Park. A search by law enforcement teams from numerous agencies, aided by thousands of citizen

volunteers, ended five days later with the discovery of the girl's body in a shallow grave along a drainage near Lake Hodges.

Three days after the girl went missing, registered sex offender John Albert Gardner III, 30, was arrested on suspicion of sexually assaulting and killing her. Police said DNA found on the victim's underwear incriminated Gardner.

Amber vanished while walking to school in February 2009. The Escondido High freshman's skeletal remains were found Saturday on a hillside in Pala, near the Riverside County line.

Gardner pleaded guilty 10 years ago to sexually assaulting a 13-year-old girl in his mother's townhouse, which is located about a mile from Rancho Bernardo Community Park.

Gardner is being investigated in Amber's disappearance. He is also a suspect in the attempted sexual assault of a woman at the park Dec. 27.

POWAY - Family, friends and classmates of slain Poway High senior Chelsea King will gather by the hundreds today in the school's football stadium -- along with throngs of people the teen never met -- to celebrate her life and to share in the grief of her loss.

Thousands of people are expected on the North County campus for the 2 p.m. memorial, which will provide a focal point for a mass outpouring of grief and outrage over the slaying of a straight-A student who seemed to have the brightest of futures.

Anticipating a crush of mourners, Chelsea's family has been issuing priority seating passes to her relatives, close friends and fellow Poway High students. Members of the general public will be allowed into the 6,000-seat stadium as space allows.

The amount of community interest in the memorial "has exceeded anyone's expectation and grows each day," King family spokeswoman Sara Muller Fraunces said earlier this week.

"Therefore, we are working closely with officials from (the school), Poway Unified School District, the Sheriff's Department, other law enforcement agencies and scores of San Diego businesses donating their services to meet the

event's needs," Fraunces said.

Chelsea's parents, Brent and Kelly King, said they "never anticipated that so many people would want to honor Chelsea in this way, and very much wish we could accommodate every single person."

"We apologize in advance if that turns out not to be the case," they added.

Gardner is also charged with sexually assaulting a woman in the same park Dec. 27.

He is also being investigated in the disappearance and apparent murder of 14-year-old Amber Dubois, who vanished while walking to school in February 2009. The Escondido High School freshman's skeletal remains were found Saturday
