To get fingerprints from a surface the police apply a fine powder (usually aluminium) to the surface where they think a print might be or where they can see one. When they blow or brush it off, the powder sticks to where the fingerprint is. They transfer this powder pattern using sticky tape to a piece of paper so they can see it more clearly. UV lights are also used by forensic scientists to illuminate fingerprints on surfaces and trace evidence on clothing such as bodily fluids and stains.

∙ 12y agoIt is a scientifically proven fact that no one on earth has the exact same fingerprint patterns. Therefore, when usable prints are lifted at the scene of a crime they can be specifically attributed to just one person. When that person is found and arrested their fingerprints will place them at the scene of the crime. OR - if their fingerprints are already on file - a search of the files will identify who they are so that a warrant can be issued.
