In the aftermath of his 1927 solo transatlantic flight, Charles Lindbergh became the most famous human being on earth. When he and his wife, Anne, had a son, Charlie, the press dubbed him Little Lindy. On March 1, 1932, kidnappers snatched Little Lindy from the family home near Hopewell, New Jersey. Negotiations stretched out for weeks, but Charlie never returned. His body was discovered not five miles from Hopewell. Now, NOVA is reopening one of the most confounding crime mysteries of all time as a team of expert investigators employs state-of-the-art forensic and behavioral science techniques in an effort to determine what really happened to Lindbergh's baby - and why.
