Police looking for missing 7-year-old, Kyron Horman, sent out forms Friday asking anyone who was at Skyline Elementary on June 4th, to answer a series of questions. Kristian Foden-Vencil reports.

The form has a picture of the second grader and his stepmother, Terri Horman. It asks people whether they saw Kyron and who he was with. It also asks whether they saw Terri Horman and when, and about her truck -- a white Ford F-250.

Captain Jason Gates with Multnomah County was asked whether the stepmother is now a suspect or person of interest.

Jason Gates: We're not in a position to talk about people of interest. She's associated with the case because she's the last person to see Kyron."

Gates said he's looking into the fact that Kyron's uncle was convicted of child molestation charges Wednesday. He also says he's looking into hundreds of other leads.

The search is now a criminal investigation.

Authorities continue to look on land and water near the school and on Sauvie Island.
