PORTLAND, Ore. -- Emergency crews are searching around Skyline Elementary School after a student didn't return home Friday afternoon.

A Portland Public Schools spokesman said Kyron Horman was dropped off for a science fair at the school by his step-mother at 8:45 a.m., but he never returned home Friday afternoon. District officials were notified that the boy was missing at around 4 p.m. Crews with the Multnomah Co. Sheriff's Office and the Portland Police Bureau have crews searching the area of the school, which is on NW Skyline Blvd. just east of NW Cornelius Pass Rd., with officers and search dogs.

If you have seen this child or know of his whereabouts, a tipline has been set up at 503-261-2847. He is wearing science-themed t-shirt.

PPS sent an automated phone message to parents of students at Skyline Elementary, but parents of students at other schools across the district have also reported getting the message. PPS Spokesman Matt Shelby said the message was only intended to go to Skyline parents, but he said it's good that more people may be aware of the missing child. Dispatchers said they received several calls from concerned parents Friday evening.
