(CNN) — Scott Lieberman, an American who lives in San Francisco, always knew that he was adopted from Chile. What he did not know was that he had been stolen as an infant.

“I lived 42 years of my life without knowing that I was stolen, not knowing what was happening down in Chile during the 70s and 80s and I just, I want people to know… There are families out there that can still be reunited,” Lieberman said.
