(Mays Landing) -- The Atlantic County Prosecutor's office says it has arrested a 27 year old Galloway woman in the February death of her newborn.

Tracy Posner of Moss Mill Road was arrested Monday afternoon at her job at the Hamilton Mall. Posner is charged with aggravated manslaughter and child endangerment in connection with the death of the baby girl. Posner's being held on bail at the Atlantic County Justice Facility.

It's alleged Posner wrapped the baby in a towel and plastic bag and put the infant under a sink after giving birth on February 24th at her home. Prosecutor's say Posner went to the emergency room the following day where doctors discovered she had given birth because the placenta was still inside her. Her arrest was delayed until autopsy results could be completed and reviewed.
