Authorities Friday were looking for the mother of a baby girl whose remains were found in a two gallon pickle jar buried near a highway.

A construction crew discovered the jar Monday while working on State Road 80, according to a statement from the Palm Beach County Sheriff's Office.

The baby's umbilical cord was still attached, and the medical examiner's office thinks the jar was buried within the last year after an autopsy.

The medical examiner's office was running tests to figure out how and when the girl died, according to the sheriff's office.
