Stephanie Lopez spent 13 years behind bars at the New Mexico Women's Correctional Facility in Grants, New Mexico after being convicted in the torture and death of her 5-month-old infant known as Baby Brianna.
Brianna's father and uncle were also convicted.
Authorities say Brianna, who died in July 2002, had been sexually assaulted and suffered multiple injuries.
Cameras were there today as Lopez was released from prison as a free woman. A family member could be seen wrapping an arm around her as she got into a car.
A short time later, a reporter caught up with her at a gas station.
The reporter asked "Do you have any comment? Do you have any comment on your release?"
Lopez answered with silence.
While Lopez did not want to talk to reporters, an official with the New Mexico Corrections Department did speak out about the high profile release.
"She was given a 27-year sentence, but because of the very weak law at the time, she earned half good time. Every day she spent in prison she earned one back off her sentence by law. We had no control over that," said Alex Sanchez, Deputy secretary of Administrative Support for the corrections department.
Public outcry led to state law now mandating 30 years in prison for child abuse resulting in death.
The Baby Brianna Foundation said it was saddened but the law cannot be enacted retroactively.
A source with knowledge of the case tells ABC7 Lopez will now serve a two-year parole while living in El Paso.
"She has a very serious conviction, so they are going to want to get to her right away. Make sure she is safe. Make sure she understands her rules. For lack of a better word, lay down the law right away," Sanchez said.
The last time we heard from Lopez was at her sentencing.
"I must live with the choices I made and suffer the loss of my freedom. But in no way does that compare to the loss of my daughter," Lopez said.
During her time behind bars, Lopez completed an associate's degree in fine arts. She also received drug rehabilitation and counseling.
"I think we can all sit here today and agree the maximum was not good enough. But she did serve her time in accordance with the law. And what we want for her is to go out and become a tax payer and we hope to never see her again," Sanchez said.
It is a new beginning for Stephanie Lopez in El Paso, just 45 miles away from Brianna's Las Cruces grave.
Nearly 350,000 people signed petitions to stop her release.
