Nneka Hollingsworth, a Payson High School student who disappeared from school during lunch hour May 11, has been missing for more than a month.
Trudy Hollingsworth, Nneka's adoptive mother, said her daughter has run away from home once before. But this latest incident is the longest the girl has left home.
"There are no words to describe the pain and agony that you go through not knowing where (your child is)," Hollingsworth said. "It's especially bad at night because you can't put them to bed."
Hollingsworth said she wants to let her daughter know that her family loves her and misses her, and wants to see her home again.
"(Whoever Nneka is with) needs to let her go, turn her over to DPS or Child Protective Services, just so long as she comes home," Hollingsworth said.
Commander Don Engler said the Police Department believes Nneka is still in Arizona and continues to pursue leads.
Nneka is 5 feet 2 inches tall, weighs 95 pounds, and has brown hair and hazel eyes. Anyone with information about her whereabouts is asked to call Detective Matt Van Camp at (928) 474-5242, ext. 209.
