The FBI is stepping up the search for a missing 7-year-old boy in Oregon. Kyron Horman was last seen five days ago walking into his elementary school.
Now, parents are so concerned about his disappearance that 40 students were kept home from school, Tuesday.
The Multnomah County Sheriff's Office said it has interviewed almost every person who was at Skyline Elementary School on Friday.
"We're going to bring you home, buddy," Multnomah Police Capt. Jason Gates said. "Nothing is more important to your family, to your friends and to us."
As time drags on, the inability to find the boy is taking an emotional toll on the searchers.
The search is also tough on parents as they drop off their children at the school. They worry if anyone else is in danger at the school while at the same time, try to calm their children.
"I'd say just try to make it as normal a day as possible, under extraordinary circumstances," Laura Kneedler, a parent said.
Horman's stepmother took him to school Friday where he was anxious to see visitors' reactions to a science exhibition, which included his display on red-eyed tree frogs. The boy was last seen walking down a hall towards his first class about 9:00 a.m.
"It is a very rare occurrence that a child will be missing from inside a school, especially a child that is this age. So this is something that is very unique, and so all possibilities are being held wide open," explained Robert Lowery, executive director of the National Center for Missing and Exploited Children
Twenty-two law enforcement agencies including the FBI are following up on more than 1,200 tips.
Meanwhile, authorities were continuing to search the areas surrounding the school.
"We're eliminating those areas where Kyron is not, and we're trying to move forward to where Kyron is so we can bring him home," Gates said.
"Above all do not give up hope, as we certainly never will," Kelly Ramirez, the sister of the boy's mother, said in a statement Monday. "He is out there and we are going to find him and bring him home safe where he belongs."
