Fingerprints (which also include palm prints and footprints) are another type of evidence that can tie individuals to crime scenes. Collecting fingerprints is a crucial process and should be one of the first things conducted when investigators arrive at the crime scene. If a print is not able to be lifted then photographs of the prints are acceptable. Fingernails are also part of evidence collection because they have striations on them which are individual characteristics. Fingernails should be collected and placed in a paper packet then placed in a paper envelope and labelled for processing.
