LAS CRUCES, N.M. (AP) – A Las Cruces mother convicted in one of New Mexico’s most horrific child abuse cases will be released after serving less than half her sentence.

The Las Cruces Sun-News reports that corrections officials have confirmed Stephanie Rene Lopez is scheduled to leave prison Sept. 25.

Lopez was sentenced to 27 years in 2003 for negligent child abuse resulting in death and child abuse after her daughter, known as Baby Brianna, died.

Brianna’s father and uncle were also convicted.

Authorities say Brianna, who died in July 2002, had been sexually assaulted and suffered multiple injuries.

Public outcry led to state law now mandating 30 years in prison for child abuse resulting in death.

The Baby Brianna Foundation says it is saddened but the law cannot be enacted retroactively.
