Today we talk about Genealogical DNA Testing and how it may be used in this case.
For decades, law enforcement was unsuccessful in their search for the "Golden State Killer," who was responsible for at least 13 murders and 45 rapes across the state of California during the 1970s and 1980s. In spite of this, detectives made an attempt to revive the case in 2017. They obtained the suspect's DNA profile from a rape kit and uploaded it to GEDmatch, which is a database that compiles the findings of numerous genealogy DNA tests.
Investigators were able to identify potential relatives of the suspect based on DNA matches to the kit. They constructed a family tree through genealogical research and then sought for potential suspects who matched the DNA profile on the tree. Two months later, they compiled a list of potential candidates for the position. And in April of 2018, law enforcement officials made an arrest of Joseph DeAngelo, who later confessed to many charges of rape and murder and was ultimately sentenced to life in prison for his crimes. DNA analysis was able to solve mysteries that had baffled law enforcement for nearly half a century in a matter of weeks or months.
The effective approach that was taken in the investigation of the Golden State Killer has given rise to a new discipline: investigative genetic genealogy (IGG). According to the FBI, there have been over 250,000 unsolved killings since the 1960s, and this number continues to grow by 6,000 cases annually. Through the integration of genetic analysis and genealogical investigation, IGG is contributing to the resolution of this problem.
So how does investigative genetic genealogy work, including how it operates, what prominent companies are doing in response, and why it is causing some controversy in the community of genealogists.
