The justices of the U.S. Supreme Court announced Monday it would not hear a case stemming from a historian’s efforts to learn about the 1946 lynching of four Black people in Georgia.

In March, the Atlanta-based U.S. Court of Appeals for the Eleventh Circuit ruled by an 8-4 vote that a lower court judge was wrong to release records from the grand jury that investigated the killing of the two Black couples at the Moore’s Ford Bridge in Walton County. Their deaths 74 years ago, for which no one was held accountable, are considered one of the precursors to the civil rights movement.
