Final answer:
Police stated that Richard Hauptmann used wood from his attic to construct the ladder used in the Lindbergh kidnapping, with matching wood found as evidence leading to his conviction.
Step-by-step explanation:
The question appears to address a historical figure, Richard Hauptmann, who is infamously known for the crime related to the Lindbergh kidnapping case. During this time, the police stated that Hauptmann had used wood from his attic to construct a homemade ladder that was subsequently used in the kidnapping of Charles Lindbergh Jr. in 1932. It was believed that evidence of this came in the form of a missing section of wood that matched the wood used in the ladder left at the crime scene. This particular testimony and evidence became a significant part of the case against Hauptmann, ultimately leading to his conviction.
