In 1997, Kim Sophoan, a widow, visited Phnom Penh with her 2 daughters Srey Lieu and Srey Mon, then aged 9 and 12. Her 'friend' Chhim Naly convinced her to leave the two girls with her so that they could go to school. Normally, Sophoan had to leave her children alone while she worked. No paperwork was signed. Ten days later, Kim Sophoan returned to Phnom Penh and learned her daughters had been adopted by a US family. Their names had been changed on the Cambodian paperwork.
