An 18-year-old woman has been killed and seven others injured in a mass stabbing at Hollow Water First Nation, a remote Indigenous community in Manitoba, police said.

The attacker, identified as 26-year-old Tyrone Simard, died shortly after the incident when he crashed a stolen vehicle into an RCMP cruiser while fleeing. The policewoman involved was critically injured but is expected to recover, according to BBC.

RCMP confirmed the woman killed was the suspect’s sister. Victims were found at two different homes, and all were known to each other within the community. One victim, Michael Raven, was stabbed in the lung while sleeping at home.

Community leaders and officials expressed grief, calling the violence devastating for the small Anishinaabe community. The attack came on the third anniversary of the James Smith Cree Nation mass stabbing in Saskatchewan, which left 11 people dead, BBC reported.
