Portland, Ore.-- The mother of Kyron Horman tried to confront Kyon s stepmother Terri Horman, at her Roseburg home this weekend.

I just felt like I needed to make a statement to her, that Kyron is a priority and we are not going to go away, said Desiree Young, the mother of Kyron Horman.

On Saturday, Young and a group of friends protested outside of Terri Horman's house. The demonstrators carried signs. They also wrote on the street in bold letters with chalk asking, Where's Kyron?

Court records indicate that Terri Horman is the focus of a criminal investigation into her stepson's disappearance. Kyron Horman was last seen at Skyline Elementary School in Portland in June 2010. The second grader has never been found. No one has been arrested.

Defense lawyers contend Terri Horman can't speak with investigators because it might jeopardize her constitutional rights.

On Saturday, Roseburg Police responded to the protest after Terri Horman's mother called 9-1-1 to complain about vandalism and trespassing.

They're here carrying signs about our grandson who is missing and they want to blame my daughter for him being gone, Carol Moulton, Terri Horman's mother, told a dispatcher.

In addition to protesting outside the Horman home, Desiree Young posted fliers throughout Roseburg, including at many businesses Terri Horman is known to visit.
