Authorities in Memphis, Tenn. charged the mother of a missing infant with abuse and neglect on Friday, the Houston Chronicle reported.

Police said 33-year-old Andrea Walker was charged with two counts of aggravated child abuse and two count of aggravated neglect or endangerment just days after her daughter, Aniston Walker, was reported missing.

Walker was booked in jail just after 4 a.m.

According to an affidavit of complaint, Walker left Aniston home with a 3-year-old while she took her 5-year-old child to school. Police said once she returned home 30 minutes later, the 7-week-old baby was missing.

The affidavit also said an experienced homicide investigator believes the baby is in grave danger, citing the cold temperature, and had likely suffered bodily injury.

On Thursday, police issued an alert saying she was last seen wearing a brown onesie with football emblems on it. She has brown eyes and weighs around 10 pounds.

Officials investigated the neighborhood where Walker and her baby lived on Friday, wearing protective vests and aided by search dogs while looking through trash bins and backyards.

Five officers performed a search near a pond and a wooded area but came up with nothing.

Police on the scene declined to comment on the investigation. Anyone with information is asked to call authorities at (901) 545 - 2677.
