Frank John Wilson was best known as the Chief of the United States Secret Service and a former agent of the Treasury Department's Bureau of Internal Revenue, later known as the Internal Revenue Service. Wilson most notably contributed in the prosecution of Chicago mobster Al Capone in 1931, and as a federal representative in the Lindbergh kidnapping case.

On March 1, 1932, Charles Augustus Lindbergh Jr., the 20-month-old son of colonel Charles Lindbergh and his wife Anne Morrow Lindbergh, was abducted from his crib in the upper floor of the Lindberghs' home, Highfields, in East Amwell, New Jersey, United States. On May 12, the child's corpse was discovered by a truck driver by the side of a nearby road.
