A man who stabbed eight relatives, killing three, in Akulivik, in Quebec's Inuit territory of Nunavik, before being shot dead by police had been confronted about tragedies in his life earlier that day, according to a Quebec coroner.

Coroner Steeve Poisson filed four separate reports on the events of June 10, 2017, on the deaths of Illutak Anautak, 19, and the three relatives he killed: his uncle, Lucassie Anautak, his aunt's partner, Eli Qinuajuak, and his cousin, Putulik Anautak, 12.

Illutak Anautak was shot six times by police and died from a bullet wound to the abdomen, the coroner said.
