"Kyron, buddy we're gonna bring you home," Capt. Jason Gates of the Multnomah County Sheriff's Office said in a press conference Monday.

Gates said that 22 state, local and federal agencies have received over 1,200 tips and they are following up on every single one.

Deputies are continuing to interview parents, students, staffers and area residents. On Monday, police were also questioning drivers near the school to find out if they spotted anything suspicious.

Kelly Ramirez, Kyron's aunt, echoed Gates optimism. "He is out there and we are going to find him and bring him home safe where he belongs," Ramirez said during the press conference.

According to CBS affiliate KOIN, Kyron's parents aren't ready to address the media.

Matt Shelby, a spokesman for Portland Public Schools, told KOIN that 45 kids were absent from Skyline Elementary School Monday, over double what is normal.

Kyron and his stepmother, Terri Moulton Horman, were together early Friday at the school, just a few miles from their house, to look at various science fair projects. The stepmother says that at about 8:45 a.m., she left and saw Kyron apparently walking toward his classroom.

At the end of the school day, when his father and stepmother did not find him getting off the school bus at 3:45, they called the school. That's when they found out that Kyron had not been in class all day long. They had not been informed, during the day, that Kyron had not been in class.

Shelby said, due to the science fair, that a lot of people were in the building that aren't usually there, which could be a lead and a potential security problem.

Anyone with information on Kyron's whereabouts is urged to call the Multhnomah County Sheriff's Office tip line at (503)-261-2847.
