What characterizes a latent fingerprint?

A fingerprint that is not visible without special techniques
A worn-out fingerprint due to weather
A fingerprint that is visible without enhancement
A smudged fingerprint created during the crime

The correct answer is: A fingerprint that is not visible without special techniques

A latent fingerprint is defined as one that is not visible to the naked eye and requires special techniques for visualization. This can include methods such as dusting with powders, using chemical treatments, or applying alternate light sources to make the otherwise invisible prints tangible for examination and comparison. Latent fingerprints are typically formed when a person touches a surface and leaves behind sweat, oils, or other residues, but these prints are not immediately apparent. Therefore, the characteristic of being invisible without assistance is what sets latent fingerprints apart from others. The other options describe fingerprints in different states—like visible fingerprints or those that may be distorted—rather than delineating the true nature of a latent fingerprint, further validating why the initial choice reflects the correct characteristic.
