City police say they were called to the Limbrick Street area early Friday morning, to find an 18-year-old man seriously hurt.
They add Liam Slipperjack, of Thunder Bay, died on Sunday at hospital.
Over the weekend, police say they arrested 18-year-old Desomond Keewaykapow, charging him with aggravated assault, but that charge will be upgraded.
A second suspect, a 17-year-old youth from Thunder Bay, was arrested early Monday morning, and charged with Second Degree murder and failure to comply with a sentence.
