MEMPHIS, Tenn. — A Memphis mother has pleaded guilty after her 7-week-old daughter died in January 2014.

Andrea Walker was supposed to stand trial Monday, but instead took a plea deal where she won’t have to serve any prison time.

While the case may be over, one fact remains.

“There will always be a lot of unanswered questions about what happened in this case,” said Defense Attorney Michael Working.

It dates back to January 2014 when Walker said she left her 7-week-old daughter, Aniston, home alone with her 3-year-old son as she took another child to school. She reported Aniston missing when she came home.

The little girl was then found dead a month later, face down in a ditch on Singleton Parkway.

“There were questions about when the child died, where the child died, when the child had been placed where she was found,” said Working.

A medical examiner was never able to determine the cause of death, but ruled it a homicide, leading Walker to be charged with her murder.

“She did not say that she was innocent,” said Defense Attorney Kamilah Turner. “She said that she did not cause the death of her child.”

Walker’s attorneys said their client accepts the blame of leaving Aniston home alone, but maintains she didn’t kill her.

“I think today’s decision was motivated by her desire to still continue being an excellent mother to two young sons that she loves very much,” said Working.

Walker pleaded guilty to reckless homicide and will be on probation for four years.

The defense said they think someone else killed Aniston, and had this case gone to trial, they would have named names. They wouldn’t elaborate on who they think killed Aniston.

Below is the Shelby County District Attorney’s Office response to the plea deal:

“Walker had been indicted on charges of first-degree murder in the perpetration of aggravated child abuse or aggravated child neglect or endangerment; aggravated child abuse involving neglect or endangerment of a child under age eight and aggravated child abuse and abuse of a corpse.
Andrea Walker told police she left baby Aniston at home with her 3-year-old brother on Jan. 9, 2014 and that when she returned 30 minutes later the baby was gone. The body of Aniston Walker was found five weeks later in a ditch at Singleton Parkway, south of Highway 385 in Millington. The medical examiner ruled the death a homicide. The plea was handled by Asst. D.A. Reggie Henderson and Asst. D.A. Karen Cook.”
