Kyron Horman Missing: 7-Year-Old Disappeared from School

PORTLAND, Ore. (CBS/KOIN/AP) The FBI's Child Abduction Rapid Deployment Team flew in a profiler on Sunday, in hopes of providing clues in the search for second grader Kyron Horman, who disappeared on Friday.

Local detectives interviewed hundreds of parents, staffers and students of Skyline Elementary School in Portland, Ore. Family members and friends distributed fliers. And, despite Sunday's rain, dozens of volunteers continued slogging through an ever-widening search area around the school.

Despite all that, 7-year-old Kyron Horman remains missing.

Kyron and his stepmother, Terri Moulton Horman, were at the school together early Friday. She took him around the school 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 finally 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.

Portland Public Schools sent out automated telephone alerts to parents, asking them to keep an eye out for the Kyron. A message also asked them to come to the school Sunday, to meet with detectives.

Sheriff Dan Staton said late Sunday night that he was "not prepared" to call the boy's disappearance a kidnapping. He described Kyron as a "missing endangered child" because more than two days had elapsed since he disappeared and because search efforts were hampered by rainy weather.

"We have developed a lot of information which has to be processed thoroughly, and I am not in a position to divulge any specifics of our investigative plan at this time," Staton said in a statement.

Kyron is three feet, eight inches tall. He weighs about 50 pounds. He was wearing orange and black cargo pants, white socks, worn black Skecher tennis shoes with orange trim and a T-shirt with the "CSI" logo.

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