Officials Ask About Kyron Horman's Stepmom

June 20, 2010 — -- Investigators are asking some very specific questions about the movements of missing 7-year-old Kyron Horman's stepmother, Terri Horman, on the day he went missing -- and a friend of Terri Horman's told ABC News that Horman was given a polygraph test.

Police have not discussed a polygraph test or its results, and have not described Terri Horman as a suspect or person of interest in the disappearance of her stepson Kyron, who went missing more than two weeks ago.

However, when authorities called off major search operations and announced that they did not believe anyone else in the Oregon community was in danger, some speculated that police may have had a suspect in mind, likely someone who knew Kyron.

"They've already said, 'Relax, we don't think there's someone out there that's going to snatch your kid. We think this is an isolated incident,'" said C.W. Jensen, a retired police captain and former homicide investigator. "They've already told us volumes."

Terri Horman was the last known person to have seen the boy. She dropped him off at school the day he vanished.

Today, police will collect a questionnaire they sent out to the community in which they asked if anyone saw Terri Horman or the white truck she was driving on the day Kyron disappeared.

"Clearly, they need more information about what she did that day, where she was that day, and that's why they put this out," Jensen said.

Multnomah County Sheriff's Capt. Jason Gates said Terri Horman is "being cooperative with investigators. The whole family is being cooperative with investigators."

Through the ordeal, the family has remained mostly out of view, rarely appearing in public and only once appearing together to read a statement.

"You mean everything to us," said Tony Young, Kyron's stepfather, that day. "And until you come home, this family's not complete. Please, Kyron, keep up the hope."

Terri Horman Has Cared for Kyron Since He Was 3 Days Old

Jaymie Finster of Portland, Ore., told ABC News that Terri Hormon, a friend of hers, understands that she was probably the last one to see Kyron and that speculation about her has increased.

"She's really tired and ready for Kyron to come home, a bit frustrated with the investigation pointing towards her and especially with the Internet blogging that's going on," Finster said.

Finster noted, however, that Kyron has been in Terri Horman's life since he was only 3 days old.

"She has been his primary caregiver," Finster said. "She actually stopped teaching to be home with him, to raise him.

"I remember her talking about when he was pre-school age and getting him ready on all the skills for reading and math ... and thoroughly enjoying being with him," Finster said. "She's a very devoted mother."
