Simply, A fingerprint can prove the precense of any suspect at a crime scene. If you have a suspect and you have a fingerprint lifted from a piece of evidence, and the two match, the chances are that your suspect was at the scene of the crime sometime recently.
Because it is now accepted as scientific fact that virtually everyone in the world has different fingerprints. This makes it statistically unlikely that anyone but you could have been at the scene of the crime.
Fingerprints provide evidence for crime-busters. Since everyone has a different fingerprint, criminals can be easily identified
They have a person's DNA in it, and if found at a crime scene, can be used by police and crime investagators/detectives to trace people and gain valuable evidence.

LATENT fingerprints.
In most cases DNA fingerprints are used in identifying crime suspects. If there are fingerprints left at a crime scene then DNA fingerprints are used to attempt to identify the suspect. There is a database of criminal fingerprints that prints can be matched to if they are in the database.
Fingerprints were first used in 1892, by Juan Vucetich to help link suspects to crimes.

Process fingerprints at a crime scene.
Fingerprint ridges differ from person-to-person, so if an offender were to touch a window at a crime scene, those fingerprints could (potentially) be traced back to him. That being said, a majority of fingerprints are only partial prints, and generally don't give as much information as crime shows like to believe. However, fingerprints can be useful at including and excluding potential suspects. If a detective has the offender's fingerprints at the crime scene, but his potential suspect's prints do not match. He is obviously investigating the wrong person.
When you touch something you leave your fingerprints on it, and everyone's fingerprints are unique. Therefore, if a particular person's fingerprints are found on an object involved in a crime, then that suggests the person those prints belong to was involved.
One major use of fingerprinting is related to criminal investigations. fingerprints can often be used to identify the perpetrator of a crime. Fingerprints are used to identify unknown victims, witnesses or suspects, to verify records, and most importantly, as links between a suspect and a crime.
To lift fingerprints from surfaces
Fingerprints are unique to people, so it's easy to tell which fingerprints belong to whom.
He or she analizes the evidence found at a crime scene and tests blood fingerprints and stuff like that
