NEW YORK (CBS/KOIN) Kyron Horman should be starting the third grade today.
As students throughout Portland, Ore. return to class, there is a sense of loss at Skyline Elementary School, where the 7-year-old vanished more than three months ago.
In the meantime, his father Kaine Horman told CBS affiliate KOIN that he's purchased all of Kyron's school supplies, packed his backpack and registered him for soccer, in preparation for when his son returns home.
Kyron was last seen on June 4 at the school's science fair. The last known image of him was taken by the last person known to see him before he went missing, his stepmother, Terri Horman.
Police have refused to call her a suspect or a person of interest, but she's become a lightning rod for scorn, especially from Kyron's biological parents.
"She needs to just come clean and do the right thing," Kyron's biological mother, Desiree Young, has said in the past.
But CBS News Correspondent Bill Whitaker points out on "The Early Show" that even if Terri Horman admitted guilt, prosecutors might still have trouble making their case.
"I don't know that even a confession itself would be enough," notes former federal prosecutor Laurie Levenson. "You have a lot of circumstantial evidence, but we don't have the key evidence. We don't have the boy."
Thursday will mark Kyron's eighth birthday and his father says he is hopeful his son will return to school with the other kids.
"The Early Show" reports that new security cameras have been installed throughout Skyline Elementary School to keep constant watch and ensure parents that the students are safe.
