Lindbergh kidnapping
Ransom payment[edit]
The ransom was packaged in a wooden box that was custom-made in the hope that it could later be identified. The ransom money included a number of
gold certificates – gold certificates which were about to be withdrawn from circulation,
[1] and it was hoped this would draw attention to anyone who was spending them.
[5][20] The bills were not
marked but their serial numbers were recorded.
Tracking the ransom money[edit]

The investigators who were working on the case were soon at a standstill. There were no developments and little evidence of any sort, so police turned their attention to tracking the ransom payments. A pamphlet was prepared with the serial numbers on the ransom bills, and 250,000 copies were distributed to businesses, mainly in New York City.
[1][20] A few of the ransom bills appeared in scattered locations, some as far away as Chicago and
Minneapolis, but those spending the bills were never found.
Per a
presidential order, all gold certificates were to be exchanged for other bills by May 1, 1933.
[34] A few days before the deadline, a man brought $2,980 to Manhattan bank for exchange; it was later realized the bills were from the ransom.
Arrest of Hauptmann[edit]

Richard Hauptmann
During a thirty-month period, a number of the ransom bills were spent throughout New York City. Detectives realized that many of the bills were being spent along the route of the
Lexington Avenue subway, which connected the East Bronx with the east side of Manhattan, including the German-Austrian neighborhood of
Yorkville.

On September 18, 1934 a Manhattan bank teller noticed a gold certificate from the ransom;
[1] a New York license plate number (4U-13-41-N.Y) penciled in the bill's margin allowed it to be traced to a nearby gas station. The station manager had written down the license number because his customer was acting "suspicious" and was "possibly a counterfeiter."
[1][5][20][35]The license plate belonged to a sedan owned by Richard Hauptmann of 1279 East 222nd Street in the Bronx,
[5] an immigrant with a criminal record in Germany. When Hauptmann was arrested, he was carrying a single 20-dollar gold certificate
[1][5] and over $14,000 of the ransom money was found in his garage.
