PACIFIC, Wash. (AP) It's been nearly three years since Kyron Horman disappeared from a Portland school where his stepmother says she dropped him off.
An age-progression photo to show what he would look like now has been released in a poster from the National Center for Missing and Exploited Children.
The poster will get added publicity by being displayed on the Gordon Trucking fleet of trucks in Washington and Oregon.
Kyron's father, Kaine Horman, was at an event Monday at the trucking company yard in Pacific where the Washington State Patrol highlighted the latest addition to the Homeward Bound Program.
For Kaine, the photo is hard to process. Not having had the chance to watch his son grow, it's painful for him to imagine the boy nearly three years older.
"I have lots of friends who have kids about his age, and (I've been) watching them grow through the years and just trying to imagine what he's (Kyron is) like now," he said.
No arrests have been made in Kyron's disappearance.
His mother, Desiree Young, is suing the stepmother, Terri Horman, seeking a court order to force her to say what happened to him.
Among the supporters of the missing boy's parents is Melissa Baum, whose own daughter, Lindsey Baum, has been missing since June 2009. Lindsey's image is also featured on trucks traveling the country.
"Let's hope that it's going to help bring them home," said Melissa Baum, "that the trucks are going to be seen by someone out there who's seen one of them."
Melissa's support has proven comforting to Kyron's parents.
"I think it gives you that sense of community that you're not alone," said Kaine. "There are other people who are going through it as well, and that's helpful. We're all hopeful."
For his son, Kaine had a message: "We're doing everything we can to find where you are. Keep positive thoughts. We'll keep doing everything from our end to get this resolved and bring you home.
"We love you. We miss you."
