Transcript for Woman Left in Phone Booth as a Baby Searches for Parents
Good evening. Tonight, you're going to go on an extraordinary journey. Have you ever wondered where you came from? Three different faces, three very different outcomes. Before the night is over, will you hold the final clue? You may be able to help. But we start with my trip to a phone booth where a woman was abandoned as a baby, just two days old. Reporter: New York City, 1965. The beatles play Shea stadium, a massive blackout turns out the lights, and that summer, on a street corner on the upper west side of Manhattan in a grimy phone booth, somebody abandons a baby. It's a little girl, apparently born just a day or two before. There's no note, no one saw anything. The only clue dangles from the baby's blanket. A St. Jude medal. The patron saint of desperate causes. So it's on this corner, 88th and Columbus. There it is. This is the phone booth. Reporter: 49 years later that desperate cause, the abandoned baby, is all grown up. Her name is Louise Jones. What does it feel like being here? It feels more strange every time I come. Reporter: A successful stock broker, and mother, satisfied with her life. But somehow that phone on the corner keeps calling her back. So what scenarios have you come up with about what might have happened? I think she was really young and really scared. And there was shame involved somehow. And there still is some shame involved. She hasn't come out to look for me at this point. Reporter: And so Louise is now looking for her. She has questions. Where have you been? Why didn't you look for me? What could it have been that was so awful that made you do that? Reporter: Like Louise Jones, John Keller was also abandoned as a baby. The 56-year-old family man works for a motorcycle dealership. He's always been grateful for his adoptive parents. But as a young man, he began wondering where he came from. So how old were you when you found out that your biological mom abandoned you when you were not quite two months old? I was in my twenties. And I had written a letter to the adoption agency. Reporter: The adoption agency revealed a disturbing past. In 1958, his birth parents lived in a basement apartment in the bronx, New York. When he was just six weeks old, John's father left his mother, and then, John's mother left him. Walked across the street, and called the police. Reporter: In that basement apartment, next to the infant, clean clothes, baby formula, and a note from Johns mother. It says "I found this hard to do, but I am desperate." Was there a time when you were angry? I was very angry for a long time. Reporter: There was another thunderbolt in that adoption agency letter. John wasn't the only one abandoned. He was shocked to find out when police found him in that apartment, there was another child there, a little 14-month-old boy. That's how John discovered at age 24, he had a brother. What did you think? You opened this letter and, holy cow. Exactly. It was, holy cow. It was like, I couldn't believe what I was Reading. Reporter: So you never saw your brother again? I've never seen my brother. Ever. Reporter: Authorities separated the brothers, who were then adopted by different families. Finding his missing brother becomes an obsession for John, he didn't even know his name until he made a trip to the New York public library. John searches old newspaper archives. Suddenly there in black and white, the story of "Two infants abandoned" complete with the names of John's mother and father, and brother. Your own life buried deep in the archives of this library. To this day, when I read that article, I get the chills. Reporter: John imagines that on that traumatic day, his big brother was somehow taking care of him. To me, he's the hero. Reporter: Why? When mommy was gone, he was there. Reporter: John longs to find his brother, to see his face, to know his name. There are questions he's been waiting 56 years to ask. And what is it you wonder most? I just want to know who my brother is. Reporter: Then there's candy Wagner, searching from the other side of the divide. A 62-year-old retired physical therapist, hoping to find healing. For nearly 20 years, she has been searching for a baby she was forced to give up in 1967. At 14, with an absent father and difficult mother, candy was dating a boy three years older. Your first boyfriend? My first for everything. There was no question that I was in very deep young love. Reporter: When this picture was taken, they didn't know it, but life was about to change drastically for the two young sweethearts. Candy was pregnant. At that time, in a small town where there's no place to hide, it is absolutely traumatic. Reporter: When candy began to show, her mother placed her far away, in a Salvation Army home for unwed mothers in New York City. And she left you there? Yes, she did. Reporter: Alone? Correct. Reporter: Alone and on her own for months, candy waits for her baby to arrive. But it's a baby she knows she will not be allowed to keep. Her mother was already planning to put the baby up for adoption. When candy and the other unwed mothers went into labor, an elevator took them through a back entrance into the adjoining hospital. So no one would see them. On April 17th, 1967, the baby arrived. It was a girl. Candy asked for her. "May I see her? May I see her?" Reporter: And they said? "No. No." Reporter: And what did you do? I yelled. I screamed. Reporter: And then did you get to see or touch her? I got to see her. And I asked to hold her. "Please let me hold her." And they said, "No, that would not be a good idea." Reporter: Candy secretly named her baby Cindy, but she never saw her again. Back home, she was expected to resume her life as if nothing had happened. I begged to keep her. And I cried nightly. Reporter: When did the crying stop? Oh, off and on. It's lasted about 47 years. Reporter: Were you looking for her in crowds? All my life. All my life. Reporter: You had noticed when you saw her when she was a baby that she had a little red mark on her cheek. She had a forceps burn. Reporter: Not realizing it was temporary, for years afterward, candy was on the lookout for a little girl with a scar. So would you find yourself looking at little girls in crowds and -- Wondering if she had a mark on her cheek. Reporter: The ordeal left a mark on candy too, although no one could see it. She graduated second in her class, went to college, got married, adopted a son of her own. But she never forgot about her secret conversations with her unborn child back in that home for unwed mothers. I could talk out loud to her. And I made promises. Reporter: What did you promise? I promised I would find her. Reporter: 47 years later, candy is so determined to keep that promise, she breaks a lifetime of silence to ask for help. She hires an unusual expert -- a professional people finder. Pam Slaton, the last resort for those desperate to find the missing branch of their family tree. Can she find candy's baby? How about John's brother, or Louise's mother? As our story continues, our cameras follow three very different journeys and capture three heart-wrenching conclusions, decades in the making. Stay with us.
