Kyron Horman's Father Won't Give Up the Search for His Son

Kyron Horman's Father Won't Give Up the Search for His Son

Kaine Horman is on a one-man mission to enlist help in finding his son, Kyron. The boy disappeared 14 months ago in Portland, Oregon, launching a desperate search that initially captivated the nation. Now more than a year later, with few leads, Kaine still refuses to give up.

The determined father's journey begins at dawn, as it does many days.

"We could be sitting at home doing nothing. The alternative is get up and do stuff," said Kaine.

The anguished father wears a sweatshirt emblazoned with his son's image and his pick-up truck also displays an urgent plea for help.

"What keeps you going?" asks INSIDE EDITION's Jim Moret.

"Just that. There are still pieces out there. He still needs to be found," Kaine says

Today Kaine is headed to a racetrack about 60 miles from home to hand out flyers. He spends countless hours behind the wheel, driving and looking for his son.

"We're trying to just keep spreading up and down the West Coast as best as we can," said Kaine.

As soon as he arrives, Kaine gets to work, setting up a display to remind people that his 2nd grader is still missing.

He's made buttons, wristbands, and t-shirts, asking people to still have faith and hope.

One man was so taken with Kyron's story that he actually painted Kyron's image and name on his truck.

"I'm just thankful for everyone and their help. It's just overwhelming," said Kaine.

Kyron disappeared on June 4th, 2010. The 7-year-old was last seen at his elementary school after his stepmother Terri Horman, a former bodybuilder, says she dropped him off at a school event. Terri and Kaine's marriage crumbled shortly after the boy vanished.

Terri Horman lives with her parents Roseburg, Oregon about three hours from Portland, where Kyron was last seen. There are signs clearly posted that they won't talk to media. Kyron's dad is frustrated because he says she won't talk to investigators either.

"She has not given us the truth," says Kaine.

"In your heart do you think Terri knows what happened?" Moret asked.

"I think she does know something. I don't know if she has all of the specifics but she has some information that I think will lead us to what happened," said Kaine.

According to reports Terri Horman was a focus in the investigation but has never been named a suspect or person of interest in Kyron's disappearance.

Kaine says Kyron's biological mother, Desiree Young, is as determined as he is to bring their son home alive and hasn't given up the search either.

The emotional strain over the past year has caused Kaine to lose 40 pounds, but with missing children like Elizabeth Smart and Jaycee Dugard being found alive, he's even more determined to keep searching.

"There are lots of positive outcomes. We need to stay focused on that. Have hope that this case will go the same way and he'll be home with us, it's just a matter of time," said Kaine.
