Samantha mom: 'Little room for anger'

"I blame every juror who let [Avila] go, every juror who sat on that trial and believed this man over those little girls," Runnion said.

LOS ANGELES, California (CNN) -- Constantly sheltering your children isn't the solution to avoiding child abductions, Samantha Runnion's mother said Thursday.

"I don't think there's a way to prevent this," Erin Runnion said Thursday on CNN's "Larry King Live." "You have to let your children be the people that they are, and there's no sense in boarding them up. That doesn't make any sense. That's no life."

Runnion said parents of children who are molested should trust the system, get them help immediately and to do everything possible to get molesters off the streets.

A day after burying her daughter, Runnion said that by speaking out, she hopes to help other mothers protect their children.

"I feel like this is my opportunity to make something out of my baby's death," she said. "We will hopefully save some babies' lives, educate some people."

Samantha Runnion was snatched kicking and screaming outside her Stanton, California, home on July 15 and then sexually assaulted and killed. Her body was discovered less than 24 hours after her disappearance, some 50 miles from her home.

"There's very little room for anger. It's all hurt. It's all sadness," Runnion said.

Samantha would have turned 6 on Friday, when family and friends plan to remember her with a birthday party in her honor.

On the night of Samantha's abduction, Runnion said her initial reaction was to go out looking for her daughter.

"I had to go out and look," she said. "I was just walking in the street looking, pounding on trunks, anything, listening for her. In my state, I heard her crying, 'Mommy.'"

Runnion said she jumped on the hood of a passing car, terrifying the driver and demanding that he open the hood of his car. The unsuspecting driver drove away.

Samantha's 5-year-old best friend witnessed the abduction.

"That little girl is a warrior," Runnion said. "She is -- for her to give the description that she did, to have the composure that she had throughout this entire thing."

Alejandro Avila, the man accused of killing Samantha, is being held without bond. He had been acquitted in a child molestation case last year.

She said more people need to listen to their children when they tell them horrible things, and believe them.

"We're talking about children," she said. "We have preconceived notions of little girls and how they might put themselves in this situation, but these are kids. They don't lie about these sort of things. They are terribly honest. They are brutally honest."
