Before Hailey disappeared on Dec. 27, she and her brother lived with their mom, Billie Dunn (pictured right), and her boyfriend, Shawn Adkins. His father, Clint (pictured left), lives just across a field in Colorado City.
Adkins moved out of the Dunn home soon after investigators started putting more focus on him. Adkins has now been named a suspect in the disappearance.
