The videos, released by the U.S. show Good Morning America (GMA), show the teenager singing mostly original songs to the camera, and according to GMA the most recent video was released just one week before she escaped via a window and alerted authorities, who rescued her remaining siblings.
"I'm accused of everything, accused in all ways, accused of what they say, what they say", she sounds to sing in one of her songs, which many today interpret as a desperate cry of help.
The most recent video on YouTube was posted a week before the teenager escaped the home by climbing through a window and alerted police.
In one, a huge pile of dirty clothes is seen in the corner of a room.
ABC News also reported the teen had an Instagram page - also using an alias - that featured selfies, photos of animals and images of singer Justin Bieber. The dogs and the youngest of the Turpin children were the only ones who did not appear to suffer from malnutrition, police have said. Authorities said the house smelled of human waste and evidence of starvation was obvious.More news: Oregon Labor Chief Weighs In On Retail Gun Rule

When authorities did a welfare check on the home, they found her other 12 siblings living in miserable conditions, with three of them shackled to furniture. They both face up to life in jail.
Tricia Andreassen and Elizabeth Flores told Good Morning Britain they had visited Louise and David Turpin, who are in custody facing a raft of child abuse and torture charges.
The case sparked national attention as details of the abuse came to light.
David and Louise Turpin were arrested and charged with numerous crimes, including multiple counts of torture and child abuse, after authorities received the tip in January.
The couple allegedly starved, choked, and beat their children. The parents, David and Louise Turpin, registered the home as a private school, which is how they kept the children from entering public school. On Friday, star cellist Yo-Yo Ma performed an exclusive concert for the siblings, People reported.
