SALEM, Ore. (CBS/KOIN/AP) Investigators trying to find missing Oregon boy Kyron Horman are distributing a flier asking if anyone saw his stepmother near Skyline School on the day the 7-year-old vanished.
The Multnomah County Sheriff's Office also wants to know if stepmother Terri Horman's white pickup truck was seen at or near the school on June 4 - the day of the disappearance.
It's been reported that Kyron attended the school's science fair that day with his stepmother, who says she last saw him walking down the hallway in the direction of his classroom around 8:45 a.m. At approximately 3:45 p.m., Terri Horman called 911, after Kyron did not return home on his school bus.
The sheriff's office has not described Terri Horman as a person of interest in the case. The boy lived with his father and stepmother about two miles from the school.
Police have been tight-lipped about the criminal investigation, but have been searching on Sauvie Island, 10 miles northwest of downtown Portland.
Exactly two weeks since the boy disappeared, police have interviewed hundreds of people, but so far there's been no arrest and no sign of the boy. "We can't release specific information about the investigation because we can't compromise it," Multnomah County sheriff's spokeswoman Lt. Mary Lindstrand told CBS affiliate KOIN. "We will not compromise the investigation."
Anyone with information on the whereabouts of Kyron Horman is asked to call the Multnomah County Sheriff's tip line at 503-261-2847.
