[Sylvester:] Welcome back to CNN LIVE SATURDAY. I'm Lisa Sylvester. Let's check a few other stories making news across America today. A manhunt is under way across the Pacific Northwest for convicted sex offender John Rollins Tuggle. The 37-year-old is suspected of stabbing his own daughter. Police say the 12-year-old girl was found tied up on a mountain road in Idaho and had been stabbed several times. She remains hospitalized in serious condition. A high-speed chase in North Carolina is captured on a police car's dashboard camera. The chase ended when the suspect lost control of the car. Incredibly, a woman and her 5-year-old daughter who were in the back seat were not hurt. Authorities have taken the teenage driver into custody. A grass fire, fanned by flames, comes within yards of several homes north of Golden, Colorado. As crews battle the blaze, some residents use their garden hoses to douse the flames. Investigators believe fireworks may be to blame The FBI is taking a larger role in the search for Natalee Holloway. Aruban authorities, still stumped in the case, are allowing the FBI to review suspect interviews, tip sheets and other relevant materials. Holloway vanished more than seven weeks ago. No formal charges have been filed in the case. Three years ago this month, 5-year-old Samantha Runnion was kidnapped, sexually assaulted and murdered. Now the man convicted of those crimes has been sentenced to death. At Friday's sentencing, Alejandro Avila heard from his victim's mother. Donna Tetreault has more from Los Angeles.
[Runnion:] I have written and rewritten what I would say to the man who killed Samantha. And you better pay attention! Because I never want to address you again. You don't deserve a place in my family's history. And so I want you to live.
[Donna Tetreault, Correspondent:] But Alejandro Avila is on his way to Death Row.
[Unidentified Male:] You shall suffer the death penalty. Said penalty shall be inflicted within the walls of the state prison at San Quentin, California.
[Tetreault:] Sentenced to death for the abduction, brutal rape and murder of 5-year-old Samantha Runnion in the summer of 2002. Samantha was outside playing with her friend, Sarah Anh, when Avila nabbed her.
[Unidentified Female:] She said, help, tell my grandma. And I did.
[Tetreault:] Kicking and screaming, she disappeared. The next day, Samantha's body was found in a remote area 50 miles from home.
[Unidentified Male:] Oh, my god, I found a dead body! Please hurry! I'm so scared right now! It was a little kid!
[Runnion:] And she fought, and I know she fought you. I know she looked at you with those amazing brown eyes, and you still wanted to kill her.
[Tetreault:] Samantha's fight sealed Avila's fate. His DNA under her fingernails and DNA, likely from Samantha's tear drops, inside his car.
[Unidentified Male:] Tragedy brings us together, yes.
[Tetreault:] More than 4,000 people attended Samantha's funeral.
[Runnion:] She wanted to be a dancer and a teacher and a mother. She loved so many things. She had so much passion for life. I'll never know what she would have become.
[Tetreault:] What Erin Runnion has become isn't anything she could have ever fathomed. Now she dedicates her life to saving other children from sexual predators, from people like Alejandro Avila.
[Runnion:] You knew it was wrong and you chose not to think about it. Well, now you have a lot of time to think about it! Don't waste it! Write it down! So that the rest of us can figure out how to stop you people!
[Tetreault:] Donna Tetreault, for CNN, Los Angeles.
[Sylvester:] Coming up tonight at 10 Eastern, we'll have the full, unedited testimony of Erin Runnion. We'll also have some tips to help you keep your children safe. Tightened security and random searches, all part of the latest security effort. How are New York's passengers reacting to these changes? We'll have a live report ahead on CNN LIVE SATURDAY.
