In 2016, a published US Senate report revealed that several dozen unaccompanied children from Central America, some as young as fourteen years old, were released from custody to traffickers where they were sexually assaulted, starved or forced to work for little or no pay. The HHS sub agency Office of Refugee Resettlement (ORR) released approximately 90,000 unaccompanied children during 2013–2015 but did not track their whereabouts or properly screen families accepting these children. To prevent similar episodes, the Homeland Security and Health & Human Services Departments signed a memorandum of understanding in 2016, and agreed to establish joint procedures within one year for dealing with unaccompanied migrant children. As of 2018 they have failed to do so. Between October and December 2017, officials from ORR tried to contact 7,635 children and their sponsors. From these calls, officials learned that 6,075 children remained with their sponsors. Twenty-eight had run away, five had been removed from the United States and fifty-two had relocated to live with a non sponsor. However, officials have lost track of 1,475 children. ORR claims it is not legally liable for the safety and status of the children once released from custody. HHS is evidenced to be actively coercing and forcing bio-substances such as antipsychotics on migrating children without consent, and under questionable medical supervision. Medical professionals state that wrongly prescribed antipsychotics are especially dangerous for children, and can cause permanent psychological damage. Medical professionals also state DHS and HHS incarceration and separation policies are likewise causing irreparable mental harm to the children. Children are also dying in HHS custody. The forced drugging, deaths, and disappearances of migrating Mexican and Central American children might be related to DHS falsely labeling them and their families as 'terror threats' before HHS manages their incarcerations. Despite a federal court order, the DHS separation practices mandated by the Trump administration's "zero-tolerance" policy have not been halted, and HHS has not stopped forcing drugs on the children it incarcerates. In the latest Center for Effective Government analysis of 15 federal agencies which receive the most Freedom of Information Act (United States) (FOIA) requests published in 2015 (using 2012 and 2013 data, the most recent years available), the DHHS ranked second to last, earning an F by scoring 57 out of a possible 100 points, largely due to a low score on its particular disclosure rules. It had deteriorated from a D- in 2013.
