. After retirement from her law career, Rae-Venter started researching her family history as a hobby in an attempt to help a family member find his biological family. As part of this work, she was asked to help identify a woman who had been abducted as a child. Her efforts in this case eventually identified
Terry Peder Rasmussen as the suspect in the
Bear Brook murders in New Hampshire. In 2019 she was included in the
''Time'' 100 list of most influential people and in 2018 was recognized in
Nature's 10, a list of "people who mattered" in science by the journal

Genetic genealogy
The field of genetic genealogy was developed largely by volunteer family history hobbyists, and Rae-Venter realized that the techniques used to identify family members in adoption cases could have wider uses in law enforcement and the identification of suspects and victims of crime. Some law enforcement agencies were initially dismissive of the idea.

to find relatives, eventually becoming one of the course's teachers.
Rae-Venter has been involved in solving several high-profile criminal cases, including the
Bear Brook murders in New Hampshire and the
Golden State Killer in California. In 2018, after her role in using genetics and genealogy to solve crimes became well-known, Rae-Venter was named in
''Nature'''s list of "
10 People who Mattered this Year".
She was recognized in the 2019
''Time'' 100 list of most influential people.
Bear Brook murders
Rae-Venter's initial involvement with using publicly-available genetic databases and family trees to contribute to criminal investigations started in 2015, when she was asked to assist investigators in identifying the true identity of a woman who had been kidnapped as an infant.
In addition to searching for family members whose DNA matched the woman's
genetic profile on publicly available websites, Rae-Venter suggested the woman submit her sample to closed databases in the hopes of finding more family members.
The case evolved to require 20,000 hours of work and a significant number of volunteers who were able to identify the woman's birth name and to put her in contact with one of her grandfathers.
In addition to identifying the woman's family and birth name, Rae-Venter and her team identified the birth mother of a relative found during the search, which allowed them to meet.
The identification of this woman led authorities to link her kidnapper to a series of murders in New Hampshire, known as the
Bear Brook murders.
Rae-Venter contributed to the eventual identification of the suspect's true identity,
Terry Peder Rasmussen, using DNA obtained from his autopsy after his death in prison. Rasmussen had been imprisoned for another murder under the name Larry Vanner.
In 2019, three of the victims of the Bear Brook murders were identified as 24 year-old Marlyse Elizabeth Honeychurch, and her daughters, Marie Elizabeth Vaughn (6 years old) and Sarah Lynn McWaters (1 year old).
Golden State Killer
Paul Holes, an inspector who had been working on the
Golden State Killer case for decades, initially contacted Rae-Venter in March 2017 for her assistance in using genealogy to search for new leads in the case. In October 2017, Rae-Venter was contributing to the team attempting to identify the killer. Rae-Venter utilized
GEDmatch, Family Tree DNA, and MyHeritage and provided structure to the team's genetic search efforts.
The team isolated a DNA sample from a Golden State Killer crime scene to create a DNA profile that could be uploaded to the genealogy databases, which produced positive matches to several distant relatives, and from these Rae-Venter was able to build a
family tree

using traditional family research techniques. By identifying relatives of the killer, investigators could first work back to find a common ancestor, and then work forward to identify all members of the family's younger generations. Once all the members of a family had been identified, investigators could then start eliminating individuals who were not suspects. In the case of the Golden State Killer, the team needed to go back to great-great-great grandparents before starting to work forward.
Multiple family trees needed to be constructed.
This information was combined with predictions about ethnicity and physical appearance to narrow down the suspect list.
Multiple pieces of evidence started to converge when the genetic profiles were considered, including the possibility that the suspect had
Italian heritage.
After the suspect had been identified, new DNA samples were collected from the suspect surreptitiously and tested against crime scene samples. The suspect's samples matched those from the killer, confirming his identity. Joseph DeAngelo was arrested on April 24, 2018.
In the immediate aftermath of the arrest, Rae-Venter chose not to be publicly identified, out of fears for her personal safety.
Several months after the arrest of the Golden State Killer, Rae-Venter allowed Holes to identify her publicly. The intervening months had seen increased interest in genetic genealogy, and additional people had been identified in the field.
After her role in the Golden State Killer case became well-known, Rae-Venter was approached to assist in at least 50 unsolved cases, including homicides and unidentified victims.
Additional cases
As one of the first public faces of genetic genealogy in law enforcement in the United States, Rae-Venter has been asked to consult on additional cases, and also to comment on the ethics of using shared community data for law enforcement purposes. She has also been one of the most sought after voices when ethical questions arise about the use of shared genetic data by law enforcement. At the conclusion of the Golden State Killer case, Rae-Venter discussed future cases that she was working on, including the
"Boy in the Box" case in Pennsylvania.
In 2019, Rae-Venter helped identify
Bobby Whitt, a boy who had been found in
Mebane, North Carolina in 1998. Based on the DNA profile of the child, she determined that the child was likely of mixed Asian and white descent. Searches of online databases identified a possible relative, who could identify the child. Whitt's family had assumed he had returned to
