His authorities issued an arrest warrant Canada at the expense of two men who are suspected of serial knife attacks in isolated indigenous communities in the country’s central west, police said.

Police launched a manhunt to find and arrest Damien Sanderson, 31, and Miles Sanderson, 30, who stabbed people at 13 different locations in Saskatchewan. At least 10 people were killed and 18 others were injured.

Two men have already been charged with murder and attempted murder. These attacks were among the bloodiest in modern Canadian history.

Aboriginal leaders in Canada said in a statement that the case may be related to drug trafficking. Police said it appeared that some of the victims were deliberately targeted, but others may have been targeted by accident.

The suspects were last seen driving a black Nissan Rogue in the city of Regina, about 200 miles (320 km) from where they carried out the attacks at James Smith Cree Neison and the village of Weldon on Sunday. “We believe that someone knows where these two are and has information that will be valuable to the police, and I urge you to contact local authorities,” Regina Police Chief Evan Bray said.

According to CBC News, Saskatoon police have been looking for Miles Sanderson since May, when he stopped communicating with his parole officer. He served time for assault, robbery, damage to other people’s property and threats.

Doreen Leese, 89, said she was sitting with her daughter on the porch of her home in Weldon on Sunday morning when a dark SUV sped past, an unusual sight for the village. A little later, a man approached them and said that he was wounded. He stood five meters away and his face was covered. When her daughter entered the house to call the police, the man left. “At that moment, we were not afraid. We just thought he was getting along and he needed help. But he didn’t wait for help to arrive, and we wondered what was going on,” the elderly woman explained.

James Smith Cree Neison is an Aboriginal community of about 3,400 people who are mainly engaged in agriculture, hunting and fishing. Weldon is a village with a population of 200 people. One of the victims is Wes Peterson, 77, a widower from Weldon. Lana Head, a mother of two, was also killed, according to her former partner.

The two suspects share the same last name, but it is currently unclear if they are related or come from the same community.
