Crossing Continents - Mississippi Smouldering

Fourteen years ago, four people were murdered in Winona, Mississippi.

The African-American man charged with their murders is facing his sixth trial.

Racial tensions helped lead to three convictions being overturned and two trials were deadlocked by hung juries.

Tom Mangold has been to the deep South to investigate and to speak to those most closely involved.

What he discovered says much about whether the high hopes of an increasingly race-neutral America are still justified at the close of the first year of Obama's presidency.
