The girls went missing about 7 p.m. Saturday and never came back. Officials searched for the girls and discovered they were in a mine shaft at about 6:20 a.m. in Chloride, about 17 miles north of Kingman.
Sheriff's spokeswoman Sandy Edwards said she did not know how far down the girls fell into the shaft. She did not know the girls' relationship.
Tragic.
Details as they come out.
