Latent prints are best described as?

• A. Visible with the naked eye
• B. Requiring immediate laboratory analysis
• C. Involve prints that are only found on fingertips
• D. Invisible to the naked eye and require development to be observed

Answer: (D)

Latent prints are impressions left by the skin that aren’t visible without some form of processing. They’re invisible to the naked eye because they’re formed from sweat and oils and don’t leave a visible mark on most surfaces on their own. Because they can’t be seen, investigators use development techniques—like dusting with powders or chemical methods (for example ninhydrin or cyanoacrylate fuming)—to reveal them. This is why the description that they’re invisible to the naked eye and require development to be observed is the best answer. In contrast, patent prints are already visible without treatment, and plastic or indentations are physical impressions in a surface. Latent prints aren’t limited to fingertips; they can be deposited on many surface areas where skin contacts something.
