In an interview Wednesday with KTAB's Priscilla Luong, Kampfer reiterated that the law enforcement side of the case is intensifying. He says officers are working to corroborate the information and tips they've put together. A focus of the investigation continues to be the only named suspect in Hailey's disappearance, Shawn Adkins.
"We're going back over things that he has made statements to and corroborating that and anything related to searches that come up with him -- and areas that he's been in and other witnesses related to him," said Kampfer about the boyfriend of Hailey's mother.
Kampfer also discussed why an arrest hasn't yet been made in the case. He made it clear that in many cases of this nature, a body is key to successful prosecution.
"In talking to the prosecutor, that (body) is something they would like to have," said Kampfer. "We're about that right now. To whatever the status of Hailey (is), we're looking for Hailey."
Kampfer said while hope remains alive that Hailey could still be alive, investigators have gone through quite a bit of disappointment as they follow leads.
It's a roller coaster," said Kampfer. "Some days we get good leads and we want to be able to follow up on things that would say that she's in good order. As time goes on and we don't have her...it's something of pessimism."
As volunteers take to fields by the dozens to search, many have questioned why Hailey's family isn't more directly involved in search efforts. Kampfer says he's the type of parent who would be out searching himself. However, he made it clear he understands those who would choose otherwise.
"Maybe there's an aspect in their minds that if they were out looking and they did find a body, they don't want to be there to discover that body," said Kampfer. "I can understand not being directly involved in the search."
Kampfer says he's given Clint and Billie Dunn his phone number so they can call him whenever they need updates.
