The Redwater, Texas teenager accused of killing a mother and her two children has plead guilty to charges of murder as part of a plea deal.

Rachel Pittman went before a judge Friday afternoon at the Bi-State Justice Building in Texarkana, Texas.

She plead guilty to the murders of Amanda Doss, 34, and her two children Guinevere Doss, 11, and Texas Johnson, 8.

Judge Leon Pesek, Jr. sentenced Pittman to two consecutive life sentences with the possibility of parole in 30 years.

In 2011, Pittman was arrested for fatally stabbing the family of three and then setting the house on fire.

In court Friday while being questioned by her attorney, Pittman broke into tears when asked about seeing the photos of the victims.

A victim impact statement was also read by Doss' parents, Glen and Wanda Prewett.

The family reminded Pittman that she was a family friend saying "You know the impact you caused. Amanda trusted and befriended you. Now how can we ever trust anyone again."

Pittman's lawyers say it was a hard day in court for everyone involved.

"If you listen to the comments the victims made, I can't imagine going through what they went through but then I can't imagine going through what this young lady went through either," said Scrappy Holmes, Defense Attorney.

Prosecutors say they're relieved that the plea will end this case and will spare the family the burden of a jury trial.

Because Pittman was 16-year old juvenile at the time of the crime, the death penalty or life without parole was not an option in this case.

Details of the murders or motive have not been released.
