JACKSONVILLE, Fla. (AP) - A north Florida woman has pleaded guilty to posing as a child welfare worker to kidnap an infant from his Haitian immigrant parents in Jacksonville.

Jasmine Marie White entered a plea Monday. The 19-year-old faces up to 40 years in prison at her sentencing next month.

Authorities say White faked a pregnancy for months before kidnapping 3-week-old Melvin Duclos in March. She used falsified paperwork and a fake Department of Children and Families badge to convince the Duclos that they needed to hand over the infant because of a child-abuse investigation.

Police and federal agents found the baby safe about 13 hours after the abduction was reported.
