the facts
they are unmarked graves
The term "mass grave" has deep and significant meaning to many around the world, particularly those who survived the Holocaust. To many, the term brings up images of genocide and execution, but the term has become more loosely defined over time by some organizations, like the United Nations.
In this case, it is important to note that the chief of the Tkemlúps te Secwépemc First Nation, Rosanne Casimir, specifically stated in her formal press conference that "this is not a mass grave".
Chief of the Cowessess First Nation, Cadmus Delorme, said in a CTV interview, "This is not a mass grave site, this is just unmarked graves."
