Hannah Thompson, 16, was found unharmed Thursday in Etowah County, Ala.
The teenager now faces charges from the Department of Juvenile Justice for running away from her father's Red Oak Flats Road home on May 18, Lumpkin County Sheriff Stacy Jarrard said.
Investigators believe Thompson had been staying in the Alabama home with her boyfriend who is also younger than 17, Jarrard said.
Authorities discovered she was in Alabama after speaking with sources who were receiving text messages from Thompson, who made sure to delete her MySpace and Facebook accounts before she left home on May 18 without word.
"I don't know if it was her phone or the friend's phone that she was with," Jarrard said.
No other charges will be filed in connection with Thompson's disappearance, Jarrard said, because there is no proof that anyone else violated the law.
When she disappeared, Thompson's family posted fliers in four counties in hopes of finding the teen, who has friends in Cleveland, Dahlonega, Oakwood, Gainesville, Cumming and Dawsonville.
