DNA evidence unravels mystery of missing Manitoba soldier from WW1

More than 100 years ago, Private Reginald Joseph Winfield Johnston went missing after leaving his Manitoba town to go serve in the First World War. He never returned and his family presumed he went missing in action and died.
In 2011, human remains were found by a construction company excavating for an expansion of a shopping mall in the village of Vendin-le-Vieil, France. The remains were connected to the First World War so the Commonwealth War Graves Commission (CWGC) was notified, and the organization took possession of the remains and artifacts.
