After seven days of searching, there's still no sign of missing 7-year-old Kyron Horman.
The Oregon boy was last seen inside his elementary school during a science fair June 4.
The search has turned into a state-wide effort with hundreds of volunteers coming from all of Oregon's 36 counties.
"I think it's hard for everybody whether you have kids or not," an officer in the search said. "We train for this, but it doesn't make it any easier."
Dozens of concerned parents have kept their kids out of school.
A fellow classmate and friend of the missing 2nd grader says his empty desk is overflowing with cards and stuffed animals waiting for his return.
"I'm feeling really really sad," Kyron's friend Tanner Pumala said. "I haven't got much sleep and I am hoping that Kyron, my best friend, will come back."
Kyron's parents released their first statement, Thursday, since his disappearance.
"The outpouring of support and continued efforts strengthened our hope," they said. "Please search your properties, your cars...please don't stop."
