What should large articles containing latent fingerprints be secured to during transport?

When transporting large articles that contain latent fingerprints, it is crucial to secure them properly to prevent damage and preserve potential evidence. Using wood or heavy cardboard is the most effective method for this purpose. These materials provide a sturdy and stable base, preventing the evidence from shifting during transport, which could otherwise obscure or destroy the latent fingerprints.

Wood or heavy cardboard also helps in minimizing movement and impact that could occur if the item were to be jostled. This stability is paramount for maintaining the integrity of the fingerprints, which are often fragile and can easily be compromised.

Other materials, like plastic wrap, while useful in preventing moisture, do not provide the necessary support for larger items. Bubble wrap offers cushioning but may not adequately secure the item in place. Regular cardboard boxes could be less reliable than the sturdiness offered by heavy cardboard or wood, especially for larger articles, which might risk being crushed or deformed.

Overall, securing large articles with wood or heavy cardboard ensures that latent fingerprints are preserved during transport, maintaining their viability as evidence.
