I suppose extreme scarring of the fingertips could have that effect, but it's hard to imagine why anyone would want to do that, if all you have to do to avoid leaving fingerpriints is to wear gloves. I should also point out that a person with obviously removed fingerprints is pretty suspicious, don't you think? :} If you mean, how can one erase latent fingerprints from an object, it depends on how the print was made, and what the object was. Fingerprints work like stamps; something will coat the tips of the fingers and, when you touch something, the pattern of the fingerprint is left behind. This can be natural oils from the body (which are actually pretty hard to detect actually), paint, soot, other oils such as motor oil, cooking oil, etc. How to clean the print depends on what made the print. For instance, prints made with paint are best removed with paint remover. Prints made with bodily fluids like sweat or oil can be removed with a detergent. Note that the acidic nature of sweat may mark or etch compounds like brass or copper, so removing the fingerprint then would be a matter of mechanically removing the etching from the metal.

How do csi take finger prints at a crime scene?
CSI technicians use powder or chemical solutions to make fingerprints visible on surfaces. They carefully lift the prints using tape or specialized tools without smudging them. The lifted prints are then analyzed and compared to known prints in databases to identify potential suspects.
How do they figure out where the finger prints are in a crime scene?
Forensic investigators use various techniques to identify and lift fingerprints from a crime scene. This typically involves dusting for prints with powders or chemicals, then lifting them with tape or adhesive sheets for analysis. Advanced methods such as using lasers or alternate light sources can also reveal hidden prints on different surfaces.
How are finger prints are detected?
Fingerprints are detected using techniques such as powder dusting, chemical solutions, or lasers. These methods help to reveal the unique ridge patterns present on the skin's surface, which are then captured and analyzed for identification purposes.
Can finger prints be transferred from one item to another?
Yes, fingerprints can be transferred from one item to another through physical contact or by touching a surface. This transfer can happen when individuals handle objects or come into contact with surfaces.
How do you send a Letter and send it USPS without it being traced back and also have no finger prints on paper or envelope?
k first you put gloves on so that your fingerprints won't show...then you don't put a return address on the top so no one can trace it back...finally just to be safe, go to a local mailbox and mail it from there :)
