Asked by PEOPLE in an exclusive new interview whether she thinks stepmom Terri Horman was involved in Kyron's disappearance, Spicher, 43, says, "I just really don't. In my heart, I really don't. In all of these years [as her friend], I have not seen anything that would lead me to believe that she is capable or motivated in any way to do something like this."
Spicher says she's told police the same thing. "They wanted me to tell them that Terri did it or that Terri knew something," she says. "I told them everything that I knew, over and over again. But I didn't tell them what they wanted to hear."
Terri Horman and Spicher, friends since meeting at a gym in 2002, have both come under scrutiny in the case. Kyron's mother, Desiree Young, has said she thinks Terri planned the boy's abduction. Kyron's father, Kaine Horman, also thinks Terri was involved – and separated from her following Kyron's disappearance.
Just last week, police released a new flyer asking for information from anyone who might have seen Terri or Spicher or anyone else near the white pickup truck Terri was driving on June 4, the morning Kyron disappeared from the Skyline School outside Portland, Ore.
Asked about her own whereabouts on June 4, Spicher says was at a 38-acre nursery preparing for a garden tour the following day. "I never left the property that day," she says.
Spicher says she stayed at Terri's house for 11 days after Kyron vanished, and that they were afraid for their own safety after getting death threats. But she wanted to be there for Terri.
"There's this horror that my friend is going through," she says. "If I thought for a second that she was capable of [foul play], I would not have been there. She would not have been my friend in the first place."
