Transcript for Search Takes Devastating Turn for Man Looking for His Brother
Reporter: Half a century after two baby brothers were abandoned in a bronx New York basement apartment building, after years of fruitless searching. At last, a breakthrough. The moment of truth for John Keller comes when professional people finder Pam Slaton arrives unannounced at his house. So she surprises you with the news. And she pulls out a paper and she goes -- I think this is your brother. I have to be honest. This looks really good. This looks really, really good. Reporter: Pam discovered a mistake in the records. She and John had been searching for years using the wrong birth date for John's brother. It was one day off. Now Pam tells John a search with the correct date has turned up his brother. Really? Really. You okay? You're giving me goose bumps. Yeah. I'm okay. I think it's time we called him. And get to the bottom of it. Okay. My name is Pam Slaton. How are you? I'm calling you because I'm trying to find someone who was born on a particular day that might have been adopted. Reporter: Sure enough, John's long lost brother is on the line. I am legitimately sitting next to your biological brother who is your full-blooded brother. So I guess the question is, how do you feel about this? Reporter: But the phone reunion takes a devastating turn. This is someone that has -- Reporter: Located after 32 years of searching John's newfound brother wants nothing to do with him. Really? It went from, "Yes, yes, yes, this is me." To, "You better not have my medical records." You better not, you know, have my social security number. I have no interest in your personal information. And I had to just take a step back and say, "Wait a second, that's not what this is about at all." My client, he would be your younger brother. Reporter: And what did he say to that? He just basically said, "I don't give a damn, and don't you ever call me again." And hung up the phone. Okay. Thank you. That unfortunately did not go well. Click. Reporter: That must hurt. That's the heartbreak. It's the abandonment again. And this is the one part of it I don't think I ever prepared for. Reporter: If for some reason, your brother were watching this segment. What would you want him to hear from you, tonight? Want him to know that I love him, unconditionally. I want him to be a part of my life. All he's gotta do is pick up the phone, call me. Door's open. And I just pray someday that he does. Reporter: Maybe things will work out better for candy Wagner, who has searched for one face in the crowd all her life. The daughter she was forced to give up for adoption. Pam has stunning news. 47 years after candy's daughter disappeared from her life, Pam thinks she may have found her. She spent 17 years looking for her daughter. It took you how long to find her? I think it was a day. Reporter: A day? Yeah. Reporter: Pam compared birth records with likely adoptive families in the county where candy lived. She found several possible matches. Including this woman, Barbara Jo gowan. By the strangest coincidence, she and candy were practically neighbors, living in the same community in upstate New York. So, I focused in on Barbara and I thought, "Wow, her parents are the right age, she's an only child. Let me take a look and see if I can find her on Facebook." Reporter: Really? She was the first one that popped out at you? There were, like, four. But she was the one that her information really looked dead on to me. Reporter: Barbara was adopted, she was born on the right birth date, and at the right hospital. Pam got in touch. To be quite honest, I thought it was somebody trying to sell me something. Reporter: And now, a mother daughter moment 47 years in the making. The daughter candy has not seen since the day she was born. The daughter she was never even allowed to touch at the door. And about to be in her arms. There it is. Hi, mom. Oh, my gosh. So beautiful. Look at you. Don't cry. Thank you for finding me. I just hope you could sense me out there. You've been in my heart every day of my life. Reporter: What was the biggest question in your mind at that point? Is she gonna like me? Reporter: "Is she gonna like me?" Yeah. Is she gonna be happy with what she sees? Reporter: As they get to know each other, mother and daughter compare notes, and marvel at living practically next door. Amazingly they discover, they'd even been in the same room three months before their reunion, when they had both attended this dance recital. Barbara watching her daughter perform, candy watching her granddaughter. Together, mother and daughter have one more memory to exorcise. They drive out to the hospital in queens, New York, where Barbara was born. The staff warm and welcoming to candy this time. Everything is going well until memories come flooding back. Do you remember that? I do remember this hall. Reporter: And then we come across that same ancient elevator. Still there, the one that carried candy and the other unwed mothers in disgrace through the back door to deliver their babies. The painful ghosts of the past suddenly present. It's too much. Candy collapses. Okay. Reporter: Back on her feet again, shaken, the teenaged unwed mother who wasn't allowed to touch her own baby so long ago, now comforted in her daughters embrace. What does a mother look for? What do you want to feel? "Are you okay?" And, were you cared for and loved, and she was. That was the closure I really needed, that her life was good. Her parents were wonderful. Reporter: A door to the past swings closed, and another door opens. Which leaves only the perplexing unsolved case of Louise Jones. Abandoned as a baby, left to fend for herself in a New York City phone booth. And 49 years later to the day, she's going back. You marked the occasion at the phone booth for a number of years by actually going to the phone booth and -- I did, yes. Reporter: Why did you do that? Because I thought if this woman is anything like me, she may show up one of these years on that day at that time and we may meet that way. A romantic thought, you know, wouldn't this be nice if she showed up? I mean, that's a fairy tale. Reporter: Pam Slaton is there. She does not have any news, she says at this point the best hope for Louise may be you, or someone else watching tonight. We were hoping that in doing this piece, somebody out there would know something and call in. Just have to hope and pray someone comes forward. Reporter: Meanwhile at the pay phone on the corner, it's a party. You got champagne? We do, we do. We are having a party. Reporter: And a toast. The searcher celebrating what she's already found, a lucrative career in finance, and a family of her own. Whoo! Reporter: Are you positive somebody knows something? There has to be. How do you hide something like that forever? The truth always comes out, somehow. Reporter: As every birthday girl knows, when you blow out the candles you always get a wish. You can guess what Louise wants, even if the most important things have already come true.
