I have been in contact with a friend of the daughter of Antoinette Marino who is assisting the daughter in the search for her mother. The daughter was placed for adoption at age one (circmstances unknown at this time).
Here is where things get very interesting: "C" and the daughter share the same first name. C's middle name is "Antoinette", the same as the missing woman Marino. I am awaiting a response from the friend to discover if the middle name of the adoptee is also "Antoinette", which would mean that both C and the adoptee share the same first and middle name. On the adoption reunion site where we discovered the adoptee, the birth father's first name is listed as "Bill" (it turns out that subsequent to the posting on the reunion site, a DNA test was done between "Bill" and the adoptee and was negative, so Bill is not the adoptee's father).
We do know that Antoinette frequented the Salinas and Big Sur areas of Northern California (approximately 100 miles from Half Moon Bay on Highway 1). Annasbro says that Antoinette looks like what he remembers the woman in the car looking like (but cannot positively identify her). And that Antoinette has not been seen by her family since about seven months prior to Anna's disappearance which would fit into a scenario where she and a male accomplice were on the run with an abducted child.
My working hypothesis (based currently on speculation and coincidences) is that Marino may have felt that society "owed" her a daughter and took Anna as a replacement, giving her the same first and middle names as her actual daughter. It is possible (but unlikely) that Antoinette Marino is the same woman as C's "mother" (I am awaiting to hear if C recognizes the pictures of Marino). If she is not the same woman, it is still possible that somehow C was transfered from Marino's possesion to C's "parents". (Remember: The above paragraph is my speculation and is not based on any verifiable evidence. It is only presented so that we have an idea of one avenue of exploration!)
Hopefully, we will have additional information shortly that will help bolster or shoot down this hypothesis.
