A fingerprint is an impression of the friction ridges of all or any part of the human finger. Fingerprints are often used as a method of identifying people, especially in forensic science and crime scene investigation, as no two prints are alike. Prints are used by crime scene investigators and coroners to help positively identify a criminal or identify a body when the identity of the individual is unknown. Fingerprints are “lifted” or taken from crime scenes and the results are analyzed and electronically compared to national databases to determine a possible match.
Most people think that fingerprints are the only prints that are left at a crime scene. Other types of prints include: lip prints, handprints, mouth prints, and more.
What do Private Investigators Need to Know?
Private investigators may need to examine and/or lift fingerprint impressions from a crime scene during an investigation, such as while investigating a theft, or when examining stolen property. Private investigators may also need to track down the results of an analysis with the appropriate lab or agency.
