The conclusion was based on an autopsy conducted by the Medical Examiner.
The discovery was made at the Sanitary District 1 Recycling Center on Bay Boulevard just after 2:20 p.m. Oct. 22nd.
Police are not sure how old the female fetus was.
It still had an umbilical cord attached.
It's not clear how it got there, who the mother is, or if it is a case of an abandoned baby.
