Oh so you were referring specifically to one of dozens of these schools "Kamloops" . Because there are undoubtedly several hundred of these graves with well over a hundred already confirmed.

Take a look a little further down the page and you can see a list with the numbers of suspected and confirmed graves per school clearly laid out. The first three examples already put the number at over a hundred.

I dont know where you imagine all those 4,126 children went when they died if not into unmarked graves?
