BILLINGS, Mont. — At least 973 Native American children died in the U.S. government's abusive boarding school system, according to the results of an investigation released Tuesday by Interior Department officials who called on the government to apologize for the schools.
The investigation commissioned by Interior Secretary Deb Haaland found marked and unmarked graves at 65 of the more than 400 U.S. boarding schools where Native American children were forcibly assimilated into white society. The findings don't specify how each child died, but officials said the causes of death included disease and abuse during a 150-year period that ended in 1969.
Additional children may have died after becoming sick at school and being sent home, officials said.
The findings follow a series of listening sessions held by Haaland over the past two years in which dozens of former students recounted harmful and often degrading treatment they endured at the hands of teachers and administrators while separated from their families.
''The federal government took deliberate and strategic action through boarding school policies to isolate children from their families, deny them their identities, and steal from them the languages, cultures, and connections that are foundational to Native people,'' Haaland, a member of the Laguna Pueblo tribe in New Mexico and the country's first Native American Cabinet secretary, said in a Tuesday call with reporters.
''Make no mistake," she added, "This was a concerted attempt to eradicate the quote, ‘Indian problem' — to either assimilate or destroy native peoples altogether."
In their initial findings two yeas ago, officials had estimated more than 500 American Indian, Alaska Native and Native Hawaiian children died at the schools. The federal government passed laws and policies in 1819 to support the schools, which were still operating in the 1960s.
The schools gave Native American kids English names, put them through military drills and forced them to perform manual labor, such as farming, brick-making and working on railroads, officials said.
