A missing 10-year-old and her 16-year-old sister who took her from South Carolina have been found in good condition at a Georgia motel.

An Amber Alert had been issued Wednesday for 10-year-old Shantelle Tylameka Hines and her older sister Keonte Lavale Hines.

Spartanburg County Sheriff Chuck Wright said a person in Monroe County, Ga., heard the alert and noticed the car the older girl was said to be driving at a hotel and called police.

Wright said both girls were unharmed.

Authorities in Forsythe, Ga., apprehended Keonte Hines.

Wright said she faces warrants for assault, battery and grand larceny. Wright said Keonte Hines will have a hearing Thursday morning.

Further charges such as kidnapping could still be filed, Wright said.

The girls' mother is on her way to Georgia to be with her 10-year-old daughter.

Police said the two girls left their grandmother's home this morning after the 55-year-old woman was beaten. Wright said Keonte Hines faces charges in that attack.

The grandmother — 55-year-old Mae Allie Hardy — was attacked about 7:49 a.m. She was being treated for her injuries at a local hospital.

Wright said the Amber Alert system worked to perfection. He said his office got about 30 calls with information, including the one that led to the girls' discovery.
