Two years ago, Raquel Par boarded a bus in her hometown of Tecpan, Guatemala, with her baby daughter for the 90-minute ride to the country's capital.

When she arrived in Guatemala City, however, she was alone.

"I took a bus that left me at Bolivar Avenue, where I had to wait to catch another one. In the meantime, I met a woman that was also waiting for the bus and she began chatting with me and my little girl. After a few minutes, she began to talk about God, and I trusted her. She offered to buy me a drink, and when I accepted, she went to a nearby store. She came back a few minutes later with a soda in a plastic bag and I drank it. Soon, I started to feel dizzy," Par told ABCNEWS.com.

"When I regained consciousness, my little girl was gone."

Children are big business in Guatemala, where international adoption is estimated to be a $100 million industry, making orphans the country's second-most lucrative export after bananas.
