The kidnapping of Charles Lindbergh's 20-month-old child on March 1, 1932 was dubbed the crime of the century at the time.
Lindbergh was the first man ever to fly solo non-stop across the Atlantic, from New York to Paris in 1927. He subsequently received the $25,000 Orteig Prize, the French Légion d'Honneur, and America's Congressional Medal of Honor. He was widely viewed as an American hero.
This explains the shock and coverage the kidnapping of his young son received in 1932. The boy disappeared from his crib on the second floor of the family house in New Jersey, where a ransom note demanding $50,000 was found. The note claimed the child was in good care. The family called the state police straight away.
A few days later, a new note upped the ransom by $20,000. What followed was a weird string of events including a retired teacher who volunteered to be a go-between and met twice with the alleged kidnapper. During the second meeting, the teacher handed over the ransom and was told to look for the child in a boat off the coast of Martha's Vineyard.
The child was never found.
A little over two months after the kidnapping, the body of the child was found in the woods close to the Lindberghs' home in New Jersey. The New York Times reported that there was "as strong possibility that he had been killed on the very night of the kidnapping."
The FBI then started to investigate the matter and on September 19, 1934, arrested Bruno Richard Hauptmann. The German-born man was hiding $13,750 of the $50,000 ransom in his garage. He was indicted for extortion and later for murder and kidnapping. His trial began in January 1935 and on February 13, a jury found him guilty. He was electrocuted on April 3, 1936.
Since the kidnapping, many conspiracy theories have surfaced including that the child's nanny was involved and that the retired teacher was also to blame. Many also maintain that Hauptmann did not get a fair trial because of Lindbergh's status and fame.
