From the first link:
The case has touched off a debate among psychologists and adoption officials about a disorder that is increasingly being diagnosed as the number of foreign adoptions rise. Last year, Americans adopted 11,340 children from foreign countries, more than twice the number adopted two decades ago. While the vast majority appear to be successful, some bring turmoil that is only beginning to be acknowledged publicly.
Whatever happened here in Greeley, reactive attachment disorder is an illness recognized by the American Psychiatric Association.

And apologies, but the parents in the 2013 Texas case were cleared, but the little boy had special-needs. From the article:
Investigators in Texas have cleared Mrs Shatto and her husband Alan, 51, an oil engineer, of blame, concluding that Max died from internal injuries probably caused by a fall from a swing.
They also said that Max’s external injuries were the self-inflicted wounds of a mentally troubled child who tore at his skin and threw himself headfirst at floors and walls.
