The community will gather at 8 p.m. Sunday at Colorado City's Ruddick Park to pray for the girl's safe return.
Hailey's father, Clint Dunn, says he'll be there from 5 p.m. to 9 p.m. and is encouraging a strong turnout.
Though investigators have arrested some key players involved in the case for largely unrelated crimes, law enforcement has seemingly not gotten any closer to locating the missing girl.
Hailey's mother and her boyfriend have been named persons of interest in the case. Authorities have gone as far as to label Shawn Adkins, Billie Dunn's boyfriend, a suspect. However, Adkins' attorney says his client has done nothing wrong and police are too focused on Adkins rather than finding Hailey.
Searchers are expected to head back out Saturday and look for any clues in Hailey's disappearance.
