Canadian authorities have found the body of a man connected to an investigation into the drowning of eight migrants, including members of an Indian family, in March when they were attempting to enter the US from Canada illegally.

The authorities said on Friday that this month they found a body from the St Lawrence River. It belonged to Casey Oakes, who disappeared in March after he was last seen operating a boat later found near the bodies of two migrant families. One of the families was from India and the other was from Romania. The Indians were identified by their kin as Pravin Chaudhary, 50, Dakshaben Chaudhary, 45, their daughter Vidhi, 23, and son Met, 20.
