Almost two and a half years since Dunn's disappearance, friends of the family say these crosses give them peace in some of their tensest days so far.
"They just keep Hailey out there, they keep her in prayer," explains Margie Sanderson
The hit pop song "Airplanes" was Hailey's favorite in 2010. It's lyrics are now painted on a bench in the "Hope for Hailey" garden.
While family and friends wait for an identification on remains found in Scurry county, their only wish is for this mysterious case to be solved.
"They are all staying positive, they're all just sitting there, waiting and hoping," says Sanderson.
In the meantime, the family is asking for the community's help with the garden. They're hoping people can come together to donate flowers and crosses to the home.
"It really lets us know that they haven't forgotten Hailey," explains Sanderson. "And that's what we never want to happen...we always want somebody to hope that Hailey is out there."
