The Lindbergh kidnapping
When the son of aviator Charles Lindbergh disappeared it was assumed he had been kidnapped.
Two months later on 12 May the child's badly decomposed body was found less than five miles (8 km) from the Lindbergh's home.
An autopsy found that he had been killed by a blow to the head shortly after the kidnapping.
It was one of the biggest stories in the US in the years before World War II.
