Forensic genetic genealogy (FGG) is a technique used by law enforcement to identify criminal suspects by combining DNA profiling with genealogical research. FGG gained prominence after it was used to identify the Golden State Killer in 2018, and it has since been employed in hundreds of cases worldwide. While FGG has proven effective in solving cold cases, it also raises concerns about efficiency, accuracy, and privacy. The process is time-consuming and expensive, requiring careful consideration of the costs involved in SNP profiling, sample processing, and data analysis, as well as genealogical research. Furthermore, the success of FGG depends on the size and diversity of the DNA databases used, as well as the presence of relevant target populations. In terms of making money, professionals in the field of genealogy, including FGG, are typically motivated by their passion rather than financial gain. However, there are opportunities to work as a genealogist for law enforcement agencies or private clients, with the potential for higher earnings through certification and specialization.

The use of genetic genealogy by law enforcement has gained prominence since the Golden State Killer's arrest in 2018
This method of investigative forensic genetic genealogy (iFGG) involves combining genetic genealogy with traditional genealogy to generate suspect leads from forensic samples. The use of iFGG has helped solve hundreds of cases in the United States and, more recently, in Europe and Australia. However, it has also raised concerns about efficiency, accuracy, and privacy. The process is time-consuming and expensive, and the success of DNA-based searching methods depends on the size of the corresponding DNA database and the presence of the relevant target population.
While genetic genealogy has proven to be a valuable tool for law enforcement, it also raises ethical questions. The use of genealogical searching can be seen as an intrusion into the rights of innocent individuals, and there are concerns about potential misuse of genetic information. To address these concerns, some states in the US have implemented laws requiring judicial authorization, consumer consent, and privacy waivers for law enforcement to access genetic information.
Despite the challenges, genetic genealogy has provided a solution to cold cases where perpetrators left DNA traces at the crime scene. It has helped law enforcement identify suspects in cases where traditional DNA-based methods and law enforcement DNA databases had failed to produce leads. The use of genetic genealogy in the Golden State Killer case brought iFGG to prominence and highlighted its potential in solving crimes.
While the use of genetic genealogy by law enforcement has gained prominence, it is important to continue addressing privacy and ethical concerns to ensure that the process is used responsibly and effectively.

Investigative genetic genealogy (IGG) involves searching databases for unknown DNA matches
Investigative Genetic Genealogy (IGG) is an innovative investigative approach that combines traditional genealogy with advanced DNA analysis to solve crimes. IGG involves searching databases for unknown DNA matches, which can help identify potential candidates as the source of an unknown DNA sample.
The process of IGG begins with forensic DNA profiling, where between 16 and 27 Short Tandem Repeat (STR) markers are analysed to generate an STR/DNA profile of an unknown sample. This unknown profile is then compared to known reference profiles, such as those collected from known suspects, and searched in a national DNA database. If no match is found, the crime scene DNA is then searched for matches among the samples stored in the database. This process is known as indirect matching and is used by law enforcement to generate suspect leads in criminal investigations.
The power of DNA-based searching methods used in IGG depends on the size of the corresponding DNA database and the presence of the relevant target population, specifically genetic relatives, in the database. These databases are not maintained by law enforcement but are instead managed by commercial genetic testing companies such as AncestryDNA, 23andMe, and MyHeritage. One such database, GEDmatch, was used to track down the Golden State Killer (GSK) in 2018, a case that brought prominence to the use of IGG in criminal investigations.
While IGG has proven successful in solving cold cases, it is important to consider the time and financial costs involved. Creating a genetic profile and conducting genealogical research can be time-consuming and expensive, and agencies should carefully select which cases are appropriate for the IGG process. Additionally, privacy concerns have been raised regarding the use of genetic genealogy databases by law enforcement, with some states implementing restrictions on access to protect consumer privacy.

Forensic genealogy is not a quick process and requires time and money to be done right
Forensic genealogy is a process that involves the use of genetic genealogy databases, combined with traditional genealogy, to generate suspect leads from forensic DNA samples in criminal investigations. This technique has gained prominence since the arrest of the Golden State Killer in 2018, and has been used in hundreds of cases in the United States, Europe, and Australia.
However, forensic genealogy is not a quick or inexpensive process. It requires significant time and financial investment to be conducted effectively. Firstly, creating a genetic profile takes time, even with faster sequencing services. The cost of SNP profiling can vary depending on the lab, and may include expenses related to sample processing and data analysis. Additionally, traditional genealogy research is often necessary, especially when dealing with individuals from countries or cultures with sparse or nonexistent record-keeping practices, making it challenging to create kinship maps.
Building a family tree can be a lengthy and complex process, requiring careful investigation to identify potential suspects. Agencies must therefore carefully assess whether a case justifies the time and financial investment required for the forensic genealogy process. The FBI, for instance, spent 43 years and $10 million trying to identify the Golden State Killer before turning to forensic genealogy for clues.
While forensic genealogy can provide valuable leads in criminal investigations, it should be used selectively, considering the resources and time involved. This ensures that agencies make efficient and judicious use of their resources while maximizing the potential for successful outcomes.

Heir tracers are compensated either by being hired by a law firm or working freelance and charging a percentage of inherited property
Forensic genetic genealogy (FGG) has been used by law enforcement agencies to solve crimes, most notably in the case of the Golden State Killer in 2018. This has led to the emergence of a new profession: forensic genetic genealogists. These professionals help law enforcement agencies identify DNA samples and provide training for detectives, medical examiners, and prosecutors in case management.
While there is a clear public interest in using FGG to solve crimes, the technique has raised concerns about efficiency, accuracy, and privacy. FGG is a time-consuming and costly process that requires careful consideration by agencies before deciding to use it. The cost of SNP profiling, for example, can vary depending on the lab, and the traditional genealogy work involved in building family trees can be challenging and time-consuming, especially when dealing with records from countries or cultures with sparse or non-existent record-keeping practices.
Heir tracers, or genealogists, are professionals who can assist in these processes. They can be hired by law firms or work as freelancers, and their compensation is typically tied to the value of the inherited property. For example, the UK-based Fleetwood Heir Hunters charge a percentage of the amount received by the heir, ensuring that their fee is always less than what the client receives. This compensation model incentivizes heir tracers to maximize the inheritance amount while providing a valuable service in locating rightful heirs and beneficiaries.
While FGG and heir tracing involve genealogical research, their applications in law enforcement and estate management, respectively, differ significantly. FGG focuses on identifying perpetrators or victims using DNA profiles and genealogical research, while heir tracing involves piecing together family trees to locate rightful heirs or beneficiaries of unclaimed estates. Both fields require specialized knowledge and skills in genealogy and related areas, contributing to their professionalization and the development of ethical guidelines to address concerns in their respective domains.

There is a need for people with skills and knowledge in family history research (salaried genealogists don't make a lot of money in the US)
Forensic genetic genealogy (FGG) is a powerful tool for law enforcement, helping to solve cold cases and identify perpetrators. However, it requires a unique set of skills and knowledge in family history research, which is where genealogists come in. The process involves the genetic comparison of crime scene DNA profiles with those in public databases, followed by genealogical research to identify investigational leads.
Genealogists with expertise in this field are in demand, as evidenced by the recent surge in law enforcement's use of FGG since the Golden State Killer case in 2018. This case demonstrated the effectiveness of combining DNA-based methods with genealogical research to find perpetrators who had previously evaded identification.
The process of FGG is intricate and time-consuming. It involves creating genetic profiles, building family trees, and investigating potential suspects, all of which require a deep understanding of genealogy and family history research. While some databases, like GEDmatch, contain millions of genetic profiles, finding relevant matches and constructing family trees is a meticulous task.
The average salary for a genealogist in the United States is approximately $80,331 per year, with an hourly rate of around $39. However, this figure can vary depending on location, with genealogists in San Jose, CA, earning an average of $116,781.
Despite the critical role they play, salaried genealogists in the US don't earn exceptionally high wages, especially considering the specialized skills and knowledge they bring to the table. The value of their expertise in solving crimes and bringing closure to victims and their families is immeasurable.
