Erica Parsons, 15, was reported missing by her older brother on July 30, 2013, but he says the last time he saw Erica was on November 19, 2011.

Erica’s adoptive parents, Sandy and Casey, say Erica isn’t missing — she went to live with her biological paternal grandmother, “Nan,” in December 2011. Police say there is no “Nan,” and Erica’s biological grandmother died five years ago.

Watch the video above where Dr. Phil talks about Erica’s birth mother, Carolyn Parsons’ reaction to Erica’s disappearance. In a Facebook post, Carolyn writes: “I am the birth mom and she has no family in Ashville and I nor her dad have no clue where she is and we love her and want to find her and know she is safe.”

Meanwhile, Dr. Phil asks Erica’s adoptive mother, Casey about her reaction when her own biological daughter went missing for a night.
