I have found this recent happening with an adoption parent sending a child back to Russia alone heartbreaking. This parent probably had pure motives when adopting - only to find out that human psychology is fragile indeed (both hers and the boy's). I have no idea what education or information she received during the adoption process - or how known/disclosed the boy's issues were - but this is a sad case whatever the case.
According to the New York Times, "Ms. Hansen — who sent Justin back to Russia unaccompanied with a note that said the boy “is violent and has severe psychopathic issues."
This boy is back in Russia after 6 months in the United States, during which time he became an American citizen. ABC news cites that several Russian families have requested to adopt this boy - but authorities are unclear about how that would pan out as he is legally an American.
For anyone looking for more information, or if learning about this for the first time, I have included some links below.
