SYNOPSIS: Thirty-seven year old Monica Libao made a promise to herself: As soon as her parents died, she would find out, once and for all, if she had really been kidnapped as an infant. Since the death of her parents, Monica spends most of her free time finding out what really happened. And she's hoping that the fact that she's missing half an earlobe may provide the best clue of all.

Monica's story begins in Chicago, in the spring of 1964. She was born on May 15th, 1964 to 58-year old retired military man, Pablo Libao, and his wife, 41-year old Clide McCall Libao. Monica was a beautiful child with light brown hair, soft hazel eyes, aquiline features, and ivory skin. Even her half-missing right earlobe (something Monica believes she was born with) added to her interesting looks. Monica remembers little about her early years other than the fact that the family moved constantly - Chicago, California, Washington, Ohio, the list goes on and on. In 1970, when Monica was 6 years old, the family settled in Texas so that Monica could enroll in first grade. There was only one problem - Monica's parents had neglected to file a birth certificate with the county, and so as far as the school was concerned, Monica didn't exist. Realizing that they had no option but to make it official, her parents finally filed a birth certificate. Monica says she was obviously too young to give it any thought and the issue was never discussed.

Monica attended school regularly, except for those days when class pictures were taken. Her parents always seemed to find a reason to keep Monica home from school that day. Over the next 10 years, Monica and her parents continued crisscrossing the country, living in roughly 25 different states, enrolling in more schools than she can remember. What she does remember is that they seemed to move to out-of-the-way places. None of her family's peculiar habits struck Monica as strange, but as she got older she began to hear her parents say disturbing things during their arguments. When her parents fought, she recalls hearing things like, "I can't believe I allowed you to do it," "she deserves to know the truth," and "it wasn't a nice thing to do." But it was one particularly vicious fight in the fall of 1980 that Monica finally heard things that she could no longer ignore. When she was 16, Monica overheard her parents fighting, saying things like "cardboard box in the bar," "roadblocks," and "we have to tell the truth."

At this point, Monica knew things weren't as they appeared to be; all the confusing things she had heard and seen over the years were finally beginning to convince her that maybe she had been kidnapped when she was a baby. On more than one occasion, Monica asked her parents to admit what was going on, but each time it was a different story: sometimes they said, "we are your parents"; other times they claimed Monica was adopted. She then discovered that her mother had a hysterectomy well before Monica was born. In 1983, Monica realized that the Social Security number she had been using was actually her father's. She also learned that her birth certificate had been forged.

For the past 20 years Monica has been searching for answers, looking for anything that will help her find peace. She's accessed her father's Navy records, her mother's and her medical files, read newspaper articles reporting infant abductions in Florida in the 1960s (looking particularly for any story mentioning an infant with a deformed earlobe), but has come up with no solid leads. Now she asks for your help to answer the question: Who really is Monica Libao?
