A familial DNA search is a search by law enforcement in DNA databases for genetic information indicating a relative of a person they seek to identify. We comment on the uptake of familial searching of DNA databases in the USA, the Netherlands, Australia, and New Zealand. Finally, following the adverse ruling by the European Court of Human Rights against the UK in regard to the S & Marper cases and the consequent introduction of the Protection of Freedoms Act (2012), we discuss the impact that changes to regulations concerning the storage of DNA samples will have on the continuing provision of familial searching of the National DNA Database in England and Wales. Familial DNA searching (sometimes referred to as "familial DNA" or "familial DNA database searching") is the practice of creating new investigative leads in cases where DNA evidence found at the scene of a crime (forensic profile) strongly resembles that of an existing DNA profile (offender profile) in a state DNA database but there is not an exact match.

The data held on the National DNA Database consists of both demographic sample data and the numerical DNA profile. Familial searching is a process by which a DNA profile of interest in a criminal case is searched against the database. Ethical Controversies of Familial Searching: The Views of Stakeholders in the United Kingdom and in Poland - Rafaela Granja, Helena Machado, 2019 2013 Nov 18;4(1):22. doi: 10.1186/2041-2223-4-22. While familial searching is now being performed in several jurisdictions in the United States, the United Kingdom has the most experience conducting familial searching of their National DNA Database. “Familial search”, using police DNA databases, was pioneered in the UK in 2004. DNA-based prediction of human externally visible characteristics in forensics: motivations, scientific challenges, and ethical considerations. In this paper we discuss the processes, utility, and governance of the familial search service in which the NDNAD is searched for close genetic relatives of an offender who has left DNA evidence at a crime scene, but whose DNA profile is not represented within the NDNAD. Abstract: The current familial searching strategies are generally based on either Identity‐By‐State (IBS) (i.e., number of shared alleles) or likelihood ratio (i.e., kinship index [KI]) assessments. Familial searching is used in countries that have decent-sized databases; in Britain, there are 5.6 million people on the National DNA database. The … USA.gov. Police departments have recently started using consumer DNA databases to conduct familial DNA searches, a practice that raises constitutional issues under the Fourth Amendment. A scoping review of quantitative evidence. In the UK, as of 2018 [26], a familial DNA search has been employed in 212 criminal cases since. What influences public views on forensic DNA testing in the criminal field? Previous studies on familial DNA searching have mostly concentrated on empiri- cal determination of the rank that a relative (of some target prole) in the database occupies, when the database is ordered according to decreasing likelihood ratio with the target, or according to decreasing number of shared alleles with the target. Trends in forensic DNA database: transnational exchange of DNA data. States should have established criteria for familial DNA searching that include the kinds of cases that may be eligible. Familial DNA Analysis Uses the DNA of Male Relatives to Catch Criminals. DEVELOPING A LIKELIHOOD RATIO APPROACH TO ‘FAMILIAL SEARCHING’ OF A DNA DATABASE USING THE ADVANCED FUNCTIONALITY OF FSS-IBD Maguire, C. N., McCallum, L. A., Jones, K. E., Storey, C. L. Forensic Science Service, Wetherby, West Yorkshire, UK In common with many laboratories around the world, FSS uses kinship analysis to resolve disputed The biological samples and the DNA profiles derived from them can be used for purposes related to the prevention and detection of crime, the investigation of an offence and for the conduct of a prosecution. Statistical and ethical considerations on familial searching. We discuss the scientific basis of the familial search approach, other DNA-based methods for eliminating individuals from the candidate lists generated by these NDNAD searches, the value of filtering these lists by age, ethnic appearance and geography and the governance required by the NDNAD Strategy Board when a police force commissions a familial search. But searching GEDmatch is potentially more effective because the … The UK NDNAD now contains the DNA profiles of approximately 6 million individuals representing 9.6% of the UK population. However, concerns arise when individuals’ tissue samples, computerized DNA profiles and personal data are stored indefinitely on a DNA database. eCollection 2020. 2019 Apr;27(4):637-646. doi: 10.1038/s41431-018-0312-2. Please enable it to take advantage of the complete set of features! We comment on the uptake of familial searching of DNA databases in the USA, the Netherlands, Australia, and New Zealand. 4. The UK NDNAD now contains the DNA profiles of approximately 6 million individuals [2] representing 9.6% of the UK population [3]. Hum Genomics. Familial Searching is the process of searching in a DNA database for relatives of a certain individual. 2014 Jan;8(1):132-6. doi: 10.1016/j.fsigen.2013.08.014. We present the FSS data in relation to the utility of the familial searching service and demonstrate the power of the technique by reference to casework examples. Philos Trans R Soc Lond B Biol Sci. Introduction Familial searching [1] is an investigative technique which can be used when a database search does not yield a full match to a crime scene profile. Epub 2010 Jan 14. NIH The NDNAD is governed by a variety of legislative instruments that mean that DNA samples can be taken if an individual is arrested and detained in a police station. In this study, the expected IBS match probabilities given relationships and the logic of the likelihood ratio method were addressed. 2019 May 23;13(1):23. doi: 10.1186/s40246-019-0207-5. 1.1 British Transport Police (BTP) will ensure that it conducts Familial searches (searches of the National DNA Database (NDNAD) to identify potential close relatives of an offender) on an intelligence led basis only for serious crimes. DNA intelligence; DNA profiling; Ethics; Familial searching; Governance; National DNA database. As a result of the growing number of DNA profiles stored in DNA databases worldwide, a controversial technology has emerged onto the forensic scene.
