ELLENWOOD, Ga. -- A Marietta mother is accused of leaving her 4-month-old infant twins in a car while she shopped at a local Wal-Mart.

Police said it happened Saturday at the Wal-Mart on Anvil Block Road in Ellenwood. Authorities said a passer-by noticed the kids alone in the car and called police.

Police said Janesia Williams, 26, left a crack in the car windows and that’s how authorities were able to remove the children, who were believed to have been inside the vehicle for about 30 minutes.

The twin infants were taken to Southern Regional Medical Center as a precaution. Doctors there said the kids were OK.

Police said the children’s father picked them up from the hospital, but Williams was taken to jail on child cruelty charges.

Williams bonded out of the Clayton County jail Sunday night just after 10:30.
