A Canadian soldier under investigation for alleged recruiting activities linked to a white supremacist organization has gone missing.

Those in the Northern Valley of Minnesota are being asked by the Roseau County Sheriff's Department to keep an eye out for Patrik Mathews, 26. His red Dodge Ram was located near Sprague, Manitoba, on Sept. 2, 2019, by Canadian authorities. The Royal Canadian Mounted Police are reporting that Mathews, who is not wanted for a crime but is listed as a missing person, may have crossed into the United States. Authorities say if citizens do see Mathews, they should not approach him.

"Obviously, we do believe that he may be under a significant amount of stress due to this investigation and the media coverage. So that's why we are asking if anyone does see him to just call police instead of engaging with him," said Cpl. Julie Courchaine, of the Royal Canadian Mounted Police of Manitoba.

If sighted, call Roseau County Sheriff's Department or the U.S. Border Patrol at 701-775-6259.
