Louis R. Vitullo (July 2, 1924 – January 3, 2006 [1]) was a Chicago police sergeant and chief microanalyst at the city's crime lab. [2]Vitullo helped to develop the rape kit, which standardized evidence collection in cases of sexual assault.

The evidence collected from the victim can aid the criminal rape investigation and the prosecution of a suspected assailant.
Evidence packaging involves the specialized packaging methods and materials used for physical evidence. Items need to be collected at a crime scene or a fire scene, forwarded to a laboratory for forensic analysis , put in secure storage, and used in a courtroom, all while maintaining the chain of custody .

Evidence might include alterations, the chain of possession, damage to the document, forgery, origin, authenticity, or other questions that come up when a document is challenged in court.
When a sample is located at a crime scene, it must be collected, processed, and transported, along with a chain of custody, to the laboratory for analysis, so that if a DNA profile is generated it can be accepted in court. Proper evidence collection and preservation is crucial to ensure evidence is not being contaminated.
