Investigative Genealogy

Cast a wider net with your crime scene DNA

Our investigative genealogical service is similar to familial search for biological relatives, but differs in significant ways:

  • We search public genetic genealogy databases, not government-owned criminal databases, such as CODIS. We identify people who have never come involved in the criminal justice system.

  • The DNA profiles generated by our affiliate lab contain vastly more information than traditional DNA profiles. Genetic relatives can be detected at far greater familial distances from four to six generations.

  • Our genetic genealogy matches can be cross-referenced by name with traditional genealogy sources, such as Therefore, existing family trees can be used to expedite tree-building and case-solving. Our methodologies create an unprecedented system for forensic human identification.

  • We can reverse engineer the suspect's family tree from their distant cousins who have been tested – even if your suspect has never had their DNA tested.  We just need somebody from their family to have tested in order to resolve these cases.

DNA and genetic genealogy are becoming major game-changers in decades-old cold cases. We offer these services at roughly half the price of other similar solution providers elsewhere.


Identify your perpetrator

Those who participate in DNA testing websites are doing it for the purposes of genealogy, family history and in some cases finding their biological family. For most people it never occurred to them that their DNA might be used to identify a serial killer or any other sort of perpetrator.

While there have been many stories about criminals being identified through DNA test results into possible biological relatives of crime scene DNA forensics, finding a company that can process this material and provide a methodology for investigative genealogists to procure that information is an advent new to the investigative toolbox.

Preserving your chain of custody

We work with DNA Solutions, an FBI QAS accredited forensic testing laboratory, to perform forensic analysis to the highest level, so your results can be used in a court of law.

DNA Solutions is also accredited to the American Association of Blood Banks (AABB) standard for relationship testing. The American Association of Blood Banks has set the standards laboratories must follow to offer accredited legal relationship testing. DNA Solutions follows these standards to assure your test will be admissible in court and accepted by other government agencies.

NDIS and CODIS vs. public databases

The national DNA database system has many components. At its core is a database of DNA information and a set of software and communication tools for comparing data collected from different sources. The database is known as the National DNA Index System (NDIS), and the system for analyzing and communicating data is called the Combined DNA Index System (CODIS).

The national DNA database system allows law enforcement officers around the country to compare forensic evidence to a central repository of DNA information. In this way, officers can better determine the identity of a suspect based on biological crime scene evidence.

There is a distinct difference between our group’s ability to collect and identify DNA evidence at the autosomal DNA level and that collected and used in the NDIS and CODIS system. While we are not law enforcement officers, we do have access to compare your autosomal DNA, mtDNA and Y-DNA evidence to that of publicly available DNA databases, like those found at These databases allow us to compare similarities in forensic DNA samples you provide with those available in the public domain.

By way of reverse engineering your DNA evidence with publicly available DNA databases, we can triangulate the most recent common ancestors (MRCA) (using chromosome analysis) and work to identify the most likely individual families they belong to through genetic genealogy.

DNA profiling has become the gold standard for victim identification in mass-casualty incidents or any forensic cases where human remains are highly fragmented and/or degraded . However, DNA profiling alone can not always be linked to known close relatives, unless DNA matches reside in the Combined DNA Index System (CODIS) or National DNA Index System (NDIS) systems.

We overcome the limitations of traditional search by converting forensic DNA samples into autosomal DNA results, using a specially equipped lab. The genetic genealogist can make an identification by triangulating  through the public DNA databases of the subjects’ distant cousins shared DNA matches. These state-of-the-art “digital fingerprints” can make identification where all other disciplines have fallen short.
