Search reveals 169 potential unmarked graves at former Canadian residential school, officials say

Officials uncovered 169 potential unmarked graves on the grounds of a former Catholic residential school in Canada, an Indigenous tribe in Alberta said Tuesday.

The Kapawe'no First Nation, which is located over 200 miles northwest of Edmonton, said the discovery was made at the former St. Bernard Mission School at the Grouard Mission site. The potential graves were identified using ground-penetrating radar (GPR) and drone imagery, officials said.
