Police now say the woman who says she found the newborn is actually the child's mother.
Police say this 21-year-old woman took the newborn to the hospital where she said she found the girl crying and abandoned near the water's edge.
That sparked a police investigation and search for the mother.

Police arrested her for filing a false police report. But so far, she is not facing charges of abandonment or neglect. The newborn is still in the hospital.
