In this episode of Full Story, a podcast from the Guardian, Rachel Humphreys speaks to Barry Kennedy, a survivor of the Marieval residential school where 751 bodies were found, who tells her: “Those are my alumni, and I have to speak to ensure that this will never, ever happen again.” He describes his experiences at the school and how they shaped the rest of his life. And as he contemplates those memories in the context of the new discoveries, he describes the importance of holding on to cultural traditions that the Canadian state once sought to eradicate.
