Law enforcement agencies have increasingly turned to third-party DNA companies, such as 23andMe, to help identify perpetrators of crimes. This has raised concerns about privacy and civil liberties. While 23andMe has stated that it has not received a law enforcement request for information in the form of a National Security Letter, it has also posted a message saying that if it receives a warrant, it will use every legal remedy possible to challenge the order. The DNA you send through genetics kits like 23andMe can be used by police in a criminal investigation, but it doesn't happen very often.

Law enforcement use of 23andMe is subject to legal and technical limitations
Law enforcement agencies have increasingly turned to third-party DNA companies, such as 23andMe, to help identify perpetrators of crimes. This technique, known as genetic genealogy, involves using DNA data to build family trees, which can help identify potential suspects in criminal investigations. By comparing DNA data from crime scene evidence to DNA data in a third-party database, investigators can identify relatives of the person responsible for the crime and narrow down the search for a suspect.
However, law enforcement use of 23andMe is subject to legal and technical limitations. 23andMe has stated that it has not received any law enforcement requests for information in the form of a National Security Letter (NSL) with an indefinite non-disclosure provision. If such a request is received in the future, the company is committed to requesting a judicial review of the order under the USA Freedom Act. 23andMe also emphasizes that its Personal Genetic Service is intended for direct-to-consumer use and that its analysis can only be performed using a saliva sample collected with its kit.
Additionally, 23andMe's Terms of Service (ToS) prohibit the use of information received through its services for forensic purposes or to contact other customers outside of designated features. It is a violation of the ToS for law enforcement to submit samples on behalf of individuals in state custody. 23andMe also cannot authenticate or verify the identity of individuals who use its service, making it challenging to connect DNA samples or accounts to specific individuals.
While law enforcement has used third-party DNA companies in criminal investigations, this approach has raised concerns about privacy and civil liberties. There are also potential issues with false accusations or wrongful convictions based on DNA data, as it is difficult to ensure that the sample provided matches the reported person. These limitations often persuade law enforcement to refrain from making requests for information from 23andMe.

23andMe has never received a law enforcement request for information in the form of a National Security Letter
23andMe is a direct-to-consumer genetic testing service that provides individuals with information and tools to learn about their DNA. The service requires customers to submit a saliva sample using a collection kit, and customers can access their genetic information through two services: the Ancestry Service and the Health + Ancestry Service. While 23andMe does provide a guide for law enforcement authorities and government agencies seeking information relating to accounts or users, it is important to note that, to date, 23andMe has never received a law enforcement request for information in the form of a National Security Letter (NSL) with an indefinite non-disclosure provision.
A National Security Letter is a type of request for information from law enforcement that includes a non-disclosure provision, which prevents the recipient from disclosing the existence of the request. 23andMe has stated that if it ever receives such a request, it is committed to requesting a judicial review of the order under the USA Freedom Act. Additionally, once the non-disclosure provision is no longer applicable, 23andMe will notify affected users about the order.
It is worth noting that 23andMe's Terms of Service (ToS) require participants to provide accurate registration information. However, the company cannot definitively authenticate or verify an individual's identity when they sign up for the service. This limitation makes it challenging to reliably connect any particular DNA sample or account to a specific individual. Furthermore, 23andMe's analysis is designed specifically for use with its own saliva collection kit, and the company cannot process samples or biospecimens collected in any other format.
While 23andMe has never received a law enforcement request in the form of an NSL, it does receive other types of requests from law enforcement agencies. These requests must be made in writing, submitted by certified mail, express courier, or in person, and signed by a responsible law enforcement officer. Even when a request meets the minimum requirements, 23andMe assesses whether it is legally required to comply, considering factors such as personal jurisdiction, validity of service, relevance of data, and specificity of the request.

23andMe's Privacy Statement and Terms of Service outline restrictions on law enforcement access
23andMe's Privacy Statement and Terms of Service outline several restrictions on law enforcement access. The company prioritises user privacy and has committed to protecting user information, including genetic data, from unauthorised access.
Firstly, 23andMe's Privacy Statement emphasises that user data will not be shared with external parties, including law enforcement, without explicit user consent. The company has never released individual user data to law enforcement and will only do so if required by a valid legal process, such as a court order or search warrant. Additionally, 23andMe has achieved ISO certifications and implemented robust security measures, such as app-based 2-step verification, to safeguard user data from unauthorised access.
Secondly, the Terms of Service (ToS) outline specific restrictions on the use of 23andMe's services by law enforcement. It is a violation of the ToS for law enforcement officials to submit samples on behalf of individuals in custody or state custody who have been charged with a crime. This restriction aims to prevent the forensic use of 23andMe's services for criminal investigations or casework, which falls outside the intended scope of the services. Furthermore, 23andMe cannot precisely authenticate or verify an individual's identity when they sign up for the service, making it challenging to connect a DNA sample or account to a specific person.
Additionally, 23andMe's ToS and Privacy Statement highlight the company's commitment to transparency and user control. The company publishes law enforcement requests on its Transparency Report, and users have the option to delete their accounts and associated data at any time. 23andMe also provides a separate Medical Record Privacy Notice for users who receive Telehealth Services, outlining how their medical information is maintained, used, and disclosed.
While 23andMe has not received a law enforcement request for information in the form of a National Security Letter (NSL), the company states that it will request judicial review of such orders pursuant to the USA Freedom Act. Overall, 23andMe's Privacy Statement and Terms of Service aim to protect user privacy and restrict law enforcement access to user data, except in cases where valid legal processes are followed.

23andMe's use for criminal investigations falls outside the scope of its intended use
In recent years, law enforcement agencies have increasingly turned to third-party DNA companies, such as 23andMe, to help identify perpetrators of crimes. Genetic genealogy has become a valuable tool for law enforcement, as it involves using DNA data to build family trees, which can help identify suspects in criminal investigations. By comparing DNA data from crime scenes to DNA data in a third-party database, investigators can identify relatives of the person responsible for the crime and narrow down their search.
However, 23andMe's use for criminal investigations falls outside the scope of its intended use. 23andMe's Personal Genetic Service is a direct-to-consumer genetic testing service that provides individuals with information and tools to learn about their DNA. While the company has a law enforcement guide, it states that the use of its services for casework and other criminal investigations is not intended. The company's Terms of Service (ToS) also requires that participants agree not to use any information received through its services for any forensic use. This includes law enforcement officials submitting samples on behalf of a prisoner or someone in state custody who has been charged with a crime, which is a violation of the ToS.
Furthermore, 23andMe has stated its commitment to protecting user information and privacy. The company has not received any law enforcement requests for information in the form of a National Security Letter (NSL) and has pledged to request judicial review of any such orders in the future. Once the non-disclosure provision no longer applies, 23andMe will notify affected users about the order. The company also cannot authenticate or verify an individual's identity when they sign up for its services, making it difficult to reliably connect a DNA sample or account to a specific person.
While 23andMe's database can be a valuable resource for law enforcement, the company's policies and commitment to user privacy place limitations on its use in criminal investigations. The potential for false accusations or wrongful convictions based on DNA data also underscores the need for caution and care in using this technique.

Law enforcement agencies have increasingly turned to third-party DNA companies to identify perpetrators
Law enforcement agencies have increasingly turned to third-party DNA companies, such as 23andMe and AncestryDNA, to help identify perpetrators of crimes. This technique, known as genetic genealogy, involves using DNA data to build family trees, which can help identify potential suspects in criminal investigations. By comparing the DNA data from crime scene evidence to DNA data in a third-party database, investigators can identify relatives of the person responsible for the crime, narrowing their search.
This approach has been successful in several high-profile cases, including the Golden State Killer case and a 1980 murder case in Virginia. In the Golden State Killer case, for example, police tracked down the suspected killer in 2018 by uploading crime-scene DNA to GEDmatch. However, this method has also raised concerns about privacy and civil liberties. Many individuals who submitted their DNA for testing were unaware that their data could be used by law enforcement, and some worry about the potential for false accusations or wrongful convictions based on DNA data.
In terms of the legal process, law enforcement may obtain a search warrant to access DNA data. In the US, the Department of Justice has issued a policy limiting searches by federal law enforcement agencies to violent crimes and DNA profiles with user consent. 23andMe has stated that it will use every legal remedy possible to challenge any warrant, and if it receives a request in the form of a National Security Letter, it will request judicial review. The company also notes that its analysis can only be performed using a saliva sample collected with its kit, and it cannot authenticate or verify the identity of the individual providing the sample, making it difficult to connect a DNA sample to a specific person.
Despite the potential for DNA data to aid in criminal investigations, 23andMe and similar companies are not likely to be useful to law enforcement due to differences in genotyping technology. Typically, police collect DNA from an unknown suspect at a crime scene and compare it to the federal government's Combined DNA Index System (CODIS). If no matches are found, they may then turn to privately owned databases. However, the genetic tests provided by 23andMe and ancestry tools cannot be used to match CODIS information or other governmental databases.
