CRYSTAL — A body found in the Mississippi River over the weekend has been identified as that of a 10-year-old Minnesota boy who has been missing for nearly a month, and police said Sunday that the boy’s father is a “primary suspect” as the case becomes a homicide investigation.

Authorities said the body of Barway Collins was found Saturday, about 10 feet from the river’s edge in Brooklyn Center. Crystal, Minnesota, Police Chief Stephanie Revering said authorities have electronic evidence that shows the boy’s father, Pierre Collins, was in that area at the time the boy disappeared. She did not elaborate on the nature of that evidence.
