A man whose body was found in the Mississippi River south of St. Louis in 1994 has finally been identified after authorities exhumed his remains to collect new DNA samples.
In the latest cold case to be solved through advances in DNA technology, the sheriff’s office in Jefferson County, Missouri, announced Tuesday that the former John Doe was Benny Leo Olson from Edwardsville, a suburb on the Illinois side of the river about 15 miles (24 kilometers) northeast of St. Louis.
