Excerpts from a February, 1995 cable from the US Embassy in Guatemala:

“Post has been using DNA genetic testing in adoption cases for more than 18 months now, and thought it would be beneficial to share both our criteria for requesting testing as well as the results themselves with the Dept. and interested Posts. Specifics on cases with negative DNA results will be included in thorough adoption fraud cable to be reported SEPTEL… [Editor's note: SEPTEL is shorthand for "separate telegram."]

…In the worst of cases, our suspicions remained just that, suspicions, since there was no true means of biologically determining the relationship between the alleged mother and child in our typical relinquishment case. Cases with I-600 petitions were referred to INS, and those without [orphan] petitions lingered in a kind of adoption purgatory in which anxious parents wrestled with their few legal options (not to mention their emotions) and the children disappeared back into the same foggy background from which they came. It has been anguishing to all parties involved, including those at Post, since the great unanswered question has been what happened to the children.”
