Apparently DHHS does speak out---sort of----at least enough to try and persuade the public they are innocent.
See their response below
A DHHS official would not comment on Ayla's case Monday, citing the department's strict confidentiality rules, but confirmed the agency's policies before placing a minor in a person's care.
"If we are placing a child with someone we do background checks and we do a home study," said Therese Cahill-Low, director of the Office of Child and Family Services.
Citing confidentiality rules, Cahill-Low also would not confirm whether DHHS was even working with Ayla's parents.

According to Trista they did not do this study even though 2 attorneys were present when it was promised. DHHS can't talk about a specific case, but they can make a blanket statement proclaiming their innocence, then hide behind privacy laws to make it difficult for the public to learn what really happens.
