Damien Sanderson, one of the suspects in a mass stabbing in Saskatchewan, Canada, that left 10 dead and 18 injured, was found dead Monday morning on the James Smith Cree Nation in a heavily grassed area near a house, according to Royal Canadian Mounted Police Assistant Commissioner Rhonda Blackmore, writes CNN.

Sanderson had injuries that were not believed to be self-inflicted, Blackmore said.

Myles Sanderson, Damien’s brother, may be injured and seek medical attention, Blackmore added: “Even if he is injured, it does not mean he is not still dangerous”.

Blackmore said Myles has a lengthy criminal record that involves both persons and property crimes and she told the public not to approach him if he is seen.

Earlier authorities said the suspects were believed to have been traveling in a black Nissan Rogue with Saskatchewan license plate 119 MPI, while noting it was unclear whether they may have changed vehicles. The vehicle was seen in Regina with two people in it.

Myles Sanderson has been charged with first degree murder, attempted murder and breaking and entering into a residence, the RCMP said.
