"(It's) the scariest thing ever," said Dunn. "I'm living every parent's nightmare. Right now, it's my reality."
Now that Marc Klaas, of KlaasKids, has come to town, Dunn tells KTAB News she has a renewed hope she'll see her daughter again.
"Instead of me being the only one saying it myself, now I have Marc and Brad telling me 'you can still be hopeful'," said Dunn. "Your daughter can still come home and be safe. You can get back to that normalcy."
Klaas says having personally been in Dunn's shoes before, he can relate to what she's going through and knows staying hopeful is what will keep her going.
"You know, if nothing else, I represent the aftermath," said Klaas. "I'm the light at the end of the tunnel? I don't know. I'm the guy who has been there, done that and still standing on my own feet moving forward."
While Billie Dunn was suspicious of her live-in boyfriend Shawn Adkins at one point, she's now not sure if he had anything to do with her disappearance.
"It's something I thought about a little bit," said Dunn. "I don't really believe that."
At this point, no one knows if Adkins had anything to do with Hailey's disappearance. Billie and Klaas are hopeful they'll see Hailey again.
"To my knowledge, there isn't any evidence of foul play found," said Dunn. "I know that my daughter can still be alive."
