"I need people to come out here," said Marc Klaas.
Klaas knows Billie Dunn's situation well. In the 90s, his daughter, Polly Hannah Klaas, went missing and was later found dead. Since then, he's formed the advocate group KlaasKids in hopes of bringing home missing children alive. Klaas regularly appears on the Nancy Grace show to discuss Hailey's case.
"We need people to come out here and search for this girl," said Klaas. "It's going to be a good day tomorrow. And we want people to take her fliers and put them in their cars and drive around with them."
Klaas says everyone needs to know who Hailey Dunn is and it's up to the Big Country to make that happen.
Klaas wouldn't say what his group was showing and sharing with searchers. However, he said he has full confidence in his groups search director Brad Dennis.
"He's determining the best places to search, he's coordinating the grids, he's working with the teams to coordinate their efforts a little bit better, and he's doing this with a couple of the volunteers from the Texas-based Laura Recovery Center," added Klaas.
Klaas says his group came to town at the request of Billie Dunn. He says he and Hailey's mother have already formed a bond.
"I'm somebody who has been what she's going through. In a certain respect, I represented hope," said Klaas.
Klaas said he's educating Billie on exactly how long cases like these can take to resolve. In some cases, it can take months or years to find closure.
"The goal is keeping her missing child in front of the camera," said Klaas.
