Fingerprints as Evidence

We have all seen police officers and detectives on television shows dust a crime scene for fingerprints and then use the prints as a way to find the person who committed a crime. Even with the advancement of other more technologically advanced forensic techniques, such as DNA profiling, fingerprinting remains a common technique for proving a person was at a crime scene.

If you have been charged with a crime and fingerprints are being presented as evidence against you, a good defense lawyer can be an invaluable tool in making sure your rights are protected. An experienced legal professional from the Law Offices of Mark T. Lassiter will provide the legal representation you need to receive a fair trial.

How Prints are Used

Fingerprinting is based on two main ideas. The process is dependent upon the facts that the ridges on the tips of a person’s fingers do not change, and ridge patterns are unique to each individual.

When a person touches a flat surface, their fingertip ridges leave marks that can be lifted using special chemicals and powders. Once the prints are secured, they can be compared to the databases of fingerprints already on file. The FBI’s fingerprint database is contains millions of individuals. Technology has made fingerprinting more effective, as partial prints can now be enhanced and a full print may be able to be constructed from a less-than-perfect sample.
