Birth parent looking for son adopted from Colombia in 1968

In 1968, I made the hardest decision of my life. I placed my son for adoption in Medellin. There is not a single day that goes by when I don't think about them. I want my child to know: it was never about not wanting them. It was about wanting more for them than I could give. The adoption was handled by an international adoption organization. I was told the family was from United States, that they were good people, that my child would have opportunities. My son would be approximately 58 years old now. I don't know their adopted name. I don't know what city they live in. But I know they're out there. If you were adopted from Medellin around 1968, if the details match, please reach out. I don't want to disrupt your life. I just want to know you're okay. I've never stopped looking. I never will.
