Latent fingerprints are not visible to the naked eye. These fingerprints are made of the sweat and oil on the skin's surface and require special processing to be revealed.
For example, if you touch a glass door, you may leave behind an invisible latent fingerprint. This fingerprint is invisible to the naked eye but can be revealed by using a dusting powder or other methods.
Here are some additional examples of situations where latent fingerprints might be left:
- Touching a weapon: A criminal who touches a weapon may leave behind latent fingerprints.
- Using a computer: A person who uses a computer may leave latent fingerprints on the keyboard, mouse, or monitor.
- Grabbing a phone: When someone picks up their phone, they may leave latent fingerprints on the screen or back.
