Why Forensic Investigative Genetic Genealogy Is Important

Criminal investigations are simplistic in theory but can be complicated in nature. First, the investigator determines if a crime occurred, then they gather evidence, identify witnesses, and study victimology. Through gathering evidence and obtaining information from witnesses, a suspect is possibly developed and charged. This process is used from the most basic shoplifting theft case to a complex homicide investigation. Criminal investigations rely on evidence to prove guilt of a suspect. This can include placing an individual(s) at the crime scene or, likewise, eliminating possible individuals as suspects. Evidence in criminal investigations can come in all shapes and forms. Fingerprints and DNA are two types of evidence that can assist in identifying a suspect. Though fingerprints and DNA are powerful evidence, they can only make an identification if that person’s fingerprints or DNA are in the Automated Fingerprint Identification System (AFIS) or the Combined DNA Index System (CODIS). This is usually where an investigation may grow cold. Technology is always advancing in the field of forensic science to potentially develop leads for cases that have hit the “cold” wall. One of these advancements is Forensic Investigative Genetic Genealogy, more commonly known as FIGG.
