'Mississippi Burning' murder case closes after 52 years

The investigation into the infamous murder of three young activists which became known as the "Mississippi Burning" civil rights case has finally closed after 52 years, the US state's attorney general said Monday. The three young men -- two Jewish and one black -- were executed in June 1964 in the midst of the "Freedom Summer" voter registration project. The brutal killings of James Chaney, 21, Andrew Goodman, 20, and Michael Schwerner, 24, rocked the nation and went on to inspire the Alan Parker film "Mississippi Burning" in 1988.
