Another Canada First Nation tribe said Tuesday that 171 unmarked "plausible graves" have been detected at the site of a former Indian Residential School.
Ground-penetrating radar was used in the cemetery area of St. Mary's Indian Residential School in Kenora, Ontario, the Wauzhushk Onigum Nation said in a press release.
"With the exception of five grave markers, the remaining are unmarked by any grave or burial markers," the release said.
The radar could have detected tree roots or large stones, so without further tests, it is not known if all the graves contain human remains.
The Wauzhushk Onigum Nation, which still has 50 survivors of the school who attended in the 1940s to 1960s, said more searches will be done at other sites "that have been identified through survivor testimony, archeological assessment and archival investigations that show burial rituals conducted by former residential school staff."
The graves are likely those of children, since Canada's National Centre for Truth and Reconciliation said at least 36 students died while attending St. Mary's. The school was operated by the Catholic Church from 1897 to 1972.
