MEMPHIS, Tenn. – Andrea Walker, whose 7-week-old daughter Aniston went missing in early January, was arrested by Memphis police on Monday, reports CBS affiliate WREG.

Escorted by her attorney, Leslie Ballin, Walker turned herself in to police. The body of a baby was found lying face down in a ditch along Singleton Parkway Sunday in Millington, Tenn.

The body was discovered by an unidentified man on a motorcycle who had pulled over to wait for his friends to catch up. He immediately called police.

Police were at the home of Andrea Walker on Sunday afternoon, though they left without Walker.

The identity of the baby has not yet been confirmed. The child had on a onesie – the same type of clothing Aniston was last seen wearing – and appeared to have been on the side of the road for some time, according to Millington investigators.

Upon discovering the body, police covered it with a tarp to preserve the scene and waited for the medical examiner to arrive.

Walker told police in January that she left Aniston at home with her 3-year-old while she took an older child to school. She returned later to find Aniston gone, Walker told authorities.

Police conducted an extensive search for the infant but were unable to find her.

Walker is already facing two charges of child abuse stemming from the incident.
