That's the one, this passage in particular:
"All FGG profiles, account information, and data shall be retained by the investigative agency for potential use during prosecution and subsequent judicial proceedings."
The DOJ policy makes clear that the search is automated from approved sources. And that no detail is supplied other than the profiles generated.
DOJ interim Policy
"Approved: 09.02.2019 1 Effective: 11.01.2019
II. Application
This interim policy applies to: 1) all criminal investigations in which an investigative agency in the Department of Justice (‘investigative agency’)3 has exclusive or concurrent jurisdiction of the crime under investigation and the agency has lawful custody, control, or authority to use a forensic sample for FGG/FGGS; or 2) any criminal investigation in which the Department provides funding to a federal, state, local, or tribal agency to conduct FGG/FGGS; or 3) any criminal investigation in which Department employees or contractors conduct genealogical research on leads generated through the use of FGGS; or 4) any federal agency or any unit of state, local, or tribal government that receives grant award funding from the Department that is used to conduct FGG/FGGS.4
III. Background
a. STR DNA Typing and CODIS
Forensic DNA typing has historically been used to compare 13-20 STR DNA markers
5 between a forensic sample
6 and one or more reference samples. 7 When a suspect’s identity is unknown, a participating crime laboratory may upload a forensic profile 8 into the FBI’s Combined DNA Index System (CODIS). CODIS is a law enforcement database that compares DNA profiles derived from forensic samples to those of known offenders.
CODIS was created by the DNA Identification Act of 1994, Pub. L. No. 103-322 (1994), codified at 34 U.S.C. § 12592. This legislation authorized the FBI to create and maintain a national database comprised of designated DNA indices that are routinely searched against one another. If a CODIS search results in a confirmed match between a forensic profile and a known offender, a law enforcement lead is generated and the name of the matching offender is released. If the search does not result in a confirmed match, no lead is generated.
3 As used in this interim policy, the term ‘investigative agency’ includes any federal, state, local, or tribal law enforcement agency that receives funding from the Department of Justice to conduct FGG/FGGS.
4 The Department will implement this policy under its federal grant programs (as applicable) through the inclusion of a specific condition(s) in federal awards.
5 STR DNA typing is a widely-used forensic DNA technology that examines 13-20 (or more) genetic locations on the non-sex chromosomes that contain 2 to 6 base-paired segments known as nucleotides, which tandemly repeat at each location. A ‘marker’ is a genetic locus, or location.
6 A ‘forensic sample’ is biological material reasonably believed by investigators to have been deposited by a putative perpetrator and that was collected from a crime scene, a person, an item, or a location connected to the criminal event. For purposes of this interim policy, the term ‘forensic sample’ also includes the unidentified human remains of a suspected homicide victim.
7 A ‘reference sample’ is biological material from a known source.
8 As used in this interim policy, ‘forensic profile’ means an STR DNA typing result, and an STR and/or mitochondrial DNA typing result for unidentified human remains, derived from a forensic sample.

b. Forensic Genetic Genealogical DNA Analysis and Searching
Forensic genealogy is law enforcement’s use of DNA analysis combined with traditional genealogy research to generate investigative leads for unsolved violent crimes. Forensic genetic genealogical DNA analysis (‘FGG’) differs from STR DNA typing in both the type of technology employed and the nature of the databases utilized.
FGG examines more than half a million single nucleotide polymorphisms9 (‘SNPs’), which replace the STR DNA markers analyzed in traditional forensic DNA typing. These SNPs span the entirety of the human genome. This allows scientists to identify shared blocks of DNA between a forensic sample and the sample donor’s potential relatives. Recombination or reshuffling of the genome is expected as DNA from each generation is passed down, resulting in larger shared blocks of identical DNA between closer relatives and shorter blocks between more distant relatives. Due to predicted levels of recombination between generations, it is possible to analyze these blocks of genetic information and make inferences regarding potential familial relationships.
Department laboratories currently do not analyze SNPs during forensic DNA casework. Thus, in appropriate cases, it is necessary to outsource biological material to vendor laboratories that perform FGG.10 After a forensic or reference sample is genotyped by a vendor laboratory, the resulting FGG profile11 is entered into one or more publicly-available open-data personal genomics DNA databases or direct-to-consumer genetic genealogy services (‘DTC service(s)’)12 (collectively referred to herein as ‘GG service(s)’). The FGG profile is then compared by automation against the genetic profiles of individuals who have voluntarily submitted their biological samples or entered their genetic profiles into these GG services (‘service users’). A computer algorithm is used to evaluate potential familial relationships between the (forensic or reference) sample donor and service users.
It is important to note that personal genetic information is not transferred, retrieved, downloaded, or retained by GG service users — including law enforcement — during the automated search and comparison process. In addition, the investigative use of FGGS involves different DNA technologies, genetic markers, algorithms, and databases from those used by
9 ‘Single nucleotide polymorphisms’ are DNA sequence variations that occur when a single nucleotide (A, T, G, or C) in a genomic sequence is altered. These variations may be used to distinguish people for purposes of biological relationship testing.
10 Contracts with vendor laboratories for FGG services should be reviewed by legal counsel to ensure that they contain appropriate language requiring maintenance of privacy and security controls for handling biological samples, FGG profiles, and other information and data both submitted to, and generated by, those vendor laboratories.
11 The term ‘FGG profile’ means the SNP-based genetic profile generated from a forensic or reference sample by a vendor laboratory for the purpose of conducting FGGS.
12 Direct-to-consumer genetic genealogy services are companies that offer a variety of DNA genomics tests and/or genetic genealogy services directly to the public (rather than through clinical health care providers), typically via customer access to secure online websites.

CODIS. Information and data derived from FGGS is not, and cannot be, uploaded, searched, or retained in any CODIS DNA Index.
IV. Limitations
If the search of an FGG profile results in one or more genetic associations,13 the GG service typically generates and provides the service user with a list of genetically associated service usernames along with an estimated relationship and (in some cases) the amount of DNA shared by those individuals. A genetic association means that the donor of the (forensic or reference) sample may be related to a service user. However, information derived from genetic associations is used by law enforcement only as an investigative lead. Traditional genealogy research and other investigative work is needed to determine the true nature of any genetic association.
A suspect shall not be arrested based solely on a genetic association generated by a GG service. If a suspect is identified after a genetic association has occurred, STR DNA typing must be performed, and the suspect’s STR DNA profile must be directly compared to the forensic profile previously uploaded to CODIS.14 This comparison is necessary to confirm that the forensic sample could have originated from the suspect."
