I'm going to go way back and focus on the Lindbergh kidnapping. Charles Lindbergh and famous aviator and his wife Anne Marrow Lindbergh were at their East Amwell, New Jersey home with their 20 month old son Charles Augustus Lindbergh Jr. On March 1, 1932 Charles Jr. was abducted from his home. Just two months later the boy of Charles Jr. was found near the Lindbergh home. The baby had died from a massive fracture of the skull. Two years went by before Bruno Hauptmann was arrested for the kidnapping and murder of the Lindbergh baby. Hauptmann was found guilty and was executed by the electric chair in 1936. This crime spurred Congress to pass the Federal Kidnapping Act also called the Lindbergh Law, which made transporting a kidnapping victim across state lines a federal crime.
The law aspects of the case found start from the time of the kidnapping, the finding of the body, the actual investigation, the arrest of Bruno Hauptmann, the trial and the death of Hauptmann by electric chair. Of course all the other aspects that went in between these parts of the time line. The psychology aspects of the crime are what was the kidnapping thinking when he took Charles Jr. The parents emotional state went out the window. The American people were effected by this. This was a very public case and everyone knew about. It scared the American people to know that someone could just come in a take a baby, this was even a baby of a famous person. We could even think of how this effected the people finding the body of Charles Jr. This case had an emotional impact not just on the family, but on the American pubic.

At the time of this case it was the big news of the day the OJ Simpson of its time if you will. Part of the psychology involved was that Lindbergh was an intensely private man who wanted nothing to do with the press, but was forced to become involved with the media that he held responsible for making his son a target.
