It's unknown how much the investigation and search would cost taxpayers, Hoyal said.
Gittins disappeared Tuesday evening wearing only pajamas and a shirt. With a major snowstorm rolling in, police and volunteers spent Wednesday and Thursday searching 17 square miles in the area near Gittins' home in Herriman, a Salt Lake City suburb about 18 miles southwest of downtown.
A key concern had been the frigid winter weather. The storm has dumped some 8 inches of snow and brought freezing temperatures.
The circumstances surrounding the case concerned authorities, especially because it appeared her departure was unplanned, Salt Lake County Sheriff Jim Winder said Thursday — before she was found.
At a Thursday news conference, Gittins' grandfather described her as a typical teenage girl who is very outgoing in some cases and very subdued in others.
The first time she ran away, she came back a short while later, Craig Hiller told reporters.
