Even though there's no too much information to release about the case, law enforcement says the investigation remains very active.
Colorado City's City Manager Pete Kampfer adds officers are still working the case.
"Sometimes these cases will go on for months and all of a sudden everything will hit," Kampfer told CBS 7.
Kampfer says despite the hard work of investigators, there remains one missing link.
"You have to have a person or body, physical evidence that something occurred, so we need Hailey and that's a big part of the case right now," said Kampfer.
Kampfer reiterated what he's been saying all along: prosecutors need more evidence before police can make an arrest.
. "We're waiting for more information related to Mr. Adkins and finding Hailey. They want to build a better case to really make sure it's a slam dunk for prosecution," said Kampfer.
Dunn is believed to have vanished from her Colorado City home on December 27.
