Not exactly what you asked, but cree journo Connie Walker has made a few podcasts about crimes comitted against indigenous people. The topic is reprehensible but the podcasting part is not.

She recently won a pulitzer and a peabody award for a documentary about residential schools, particularly those attended by her late father and his family.
