Kentucky State Police say Brandi Higdon had last been seen in Clarkson on March 26.
She had left a note saying she had run away.Tyler Hill,18, accompanied her. State Police say he is also back.
KSP Public Affairs Officer, Norman Chaffins, says, "It is not likely the two teenagers would have returned so soon had it not been for their picture posted on social networking sites, the KSP web site, local radio websites, and various other media outlets."
State police will be talking with both teenagers and their families about this investigation.
