ROSEBURG, Ore. -- The mother of missing Portland boy Kyron Horman started a new campaign to put pressure on the boy s stepmother, who has long been a focus of the investigation.
Kyron's mother, Desiree Young, told KGW that we are taking the fight to her.

Young, her husband and other friends and family went to Roseburg, where Terri Moulton Horman has been living with her parents since a couple of week's after Kyron was last seen.
I know horrifying things about her (Terri Horman) and specifically about my son, Young said, She has a severe hatred for him. And she is capable of hurting him and I believe that's what she did.
Posters were put up around parts of town that Terri Horman might frequent. The group took special care to put up posters near the home of Terri Horman's parents.
How does she sleep at night? Young asked of Terri Horman. She needs to see Kyron's face every day. She needs to be reminded what she's done.
Kyron Horman has been missing since he disappeared from Skyline Elementary school in Portlandon June 4, 2010. His stepmother was reportedlythe last person to see him.

It's not right that Terri gets to have a free life while my son is missing, Young said. There's only one person that knows where Kyron is and when you see her, you need to ask where he is.
Young also said it's time to name Horman a suspect in the case, something the Multnomah County Sheriff's Office has declined to do.

We are putting the pressure on Terri, Young told KGW. We are bringing it to her. She needs to know we will not rest until Kyron is brought home.
Young, her husband Tony and members of their family were handing out new fliers (pictured, above) highlighting Kyron.
I think she's angry, she's frustrated and she's hurt. And she wants Terri Horman to be frustrated, angry and be hurt, former detective C.W. Jensen said.
The former homicide detective warned public outrage won't speed things up and that such investigations take time.
You know, somehow people think that the cops are going to kick the door down and beat her with a rubber hose and get her to confess, that's not going to happen.
In an interview with reporters, Young was asked if she believes Kyron is still alive.
In the beginning of the case, I did believe that, she said. I hope every day that Kyron comes through the door and that we find him okay. I want that with everything... But with the information and evidence that I have been presented against Terri, I'm confident that she probably did something to him.
