Gordon Trucking will add another missing child's photo to its fleet of trucks -- a boy who went missing near Portland in 2010.
There are 16 children's photos from Washington and Oregon featured on the trucks, including Sofia Juarez of Kennewick, who has been missing since 2003.
She vanished the day before her fifth birthday when she went to a store near her Kennewick home.
Kyron Horman, missing since age 7, has been in the Homeward Bound program since 2011. His age-enhanced photo will be unveiled Monday in Pacific.
Never miss a local story.
Age progression software has been applied to the photos to show what the children would look like today.
The program, created in 2005, has assisted in the recovery of six missing children.
