ABC’s 20/20 did an extensive episode years ago (maybe more than 20 years) about child trafficking in southeast Asia. The story was likely about Thailand or Malaysia. I think the correspondent was Tom Jarriel though I could be wrong about that. I remember part of the story revolved around the tracking of an American medical doctor who “vacationed” there each year and how they caught him in a brothel.
I would greatly appreciate it if someone could provide a link. I’ve tried and cannot locate a link to that important story.
I got nothing in several searches.
However, I did find at site that you can view list of episodes all the way back to 2002.
