Article of the week -- my week at least, as I may have been slow coming to it -- has to be “'Not a Shred of Evidence': Settler Colonial Networks of Concealment and the Birtle Indian Residential School" by Tyle Betke. It is in the most recent issue of the Canadian Historical Review (and likely available only to subscribers). It's about sex slavery, and death, and coverup, at a residential school in the early to mid twentieth century. 
Birtle Residential School
It ought to put an end to the "until you prove every case and exhume every body, it's okay to assume it never happened" approach to the whole issue of abuse at residential schools. Probably it will not.
Since the link may not make the full text available, I'm copying part of one representative paragraph, concerning the experience of one family:
Lazenby’s superiors within the DIA also helped cover up the truth by discrediting the girls and their family members. The father of the girls was known to the DIA. He was one of many Indigenous parents across Canada who advocated for the proper education and treatment of their children. He had sent multiple petitions and letters of complaints to the DIA Upon hearing the news of Currie’s charges, Deputy Superintendent General of Indian Affairs Duncan Campbell Scott characterized the girl’s father as “a trouble maker.” Scott surmised that the father was causing trouble because of having “become embittered recently” when his other daughter died while running away from the school.
