The missing, the martyred and the disappeared: Global networks, technical intensification and the end of human rights genetics.

In 1984, a group of Argentine students, trained by US academics, formed the Argentine Forensic Anthropology Team to apply the latest scientific techniques to the excavation of mass graves and identification of the dead, and to work toward transitional justice. This inaugurated a new era in global forensic science, as groups of scientists in the Global South worked outside of and often against local governments to document war crimes in post-conflict settings. After 2001, however, with the inauguration of the war on terror following the September 11th attacks on the World Trade Center in New York, global forensic science was again remade through US and European investment to increase preparedness in the face of potential terrorist attacks. In this paper, I trace this shift from human rights to humanitarian forensics through a focus on three moments in the history of post-conflict identification science. Through a close attention to the material semiotic networks of forensic science in post-conflict settings, I examine the shifting ground between non-governmental human rights forensics and an emerging security- and disaster-focused identification grounded in global law enforcement. I argue that these transformations are aligned with a scientific shift towards mechanized, routinized, and corporate-owned DNA identification and a legal privileging of the right to truth circumscribed by narrow articulations of kinship and the body.

Colombian forensic genetics as a form of public science: The role of race, nation and common sense in the stabilization of DNA populations.

Abstract This article examines the role that vernacular notions of racialized-regional difference play in the constitution and stabilization of DNA populations in Colombian forensic science, in what we frame as a process of public science. In public science, the imaginations of the scientific world and common-sense public knowledge are integral to the production and circulation of science itself. We explore the origins and circulation of a scientific object--'La Tabla', published in Paredes et al. and used in genetic forensic identification procedures--among genetic research institutes, forensic genetics laboratories and courtrooms in Bogotá. We unveil the double life of this central object of forensic genetics. On the one hand, La Tabla enjoys an indisputable public place in the processing of forensic genetic evidence in Colombia (paternity cases, identification of bodies, etc.). On the other hand, the relations it establishes between 'race', geography and genetics are questioned among population geneticists in Colombia. Although forensic technicians are aware of the disputes among population geneticists, they use and endorse the relations established between genetics, 'race' and geography because these fit with common-sense notions of visible bodily difference and the regionalization of race in the Colombian nation.

[The forensic medical identification of the members of the Demidov family].

The objective of the present study was to elucidate the genetic profiles of the biological materials taken from four graves in the Demidov family vault in order to establish kinship between its members. According to the archival documents, two graves contained the remains of Pyotr Grigor'evich Demidov, an adjutant-general for the emperor Aleksandr II, and his wife Elizaveta Nikolaevna Demidova (Bezobrazova). Also, it was supposed that two other graves contained the remains of Grigory Petrovich Demidov and Ekaterina Petrovna Demidova (married name princess Kudasheva), the son and the daughter of P.G. Demidov and E.N. Demidova. The bodies remained in the half-ruined crypt during approximately 150 years under conditions of enhanced humidity and seasonal temperature fluctuations which made their bone tissue virtually unsuitable for the genetic analysis. Genotyping was performed with the use of standard AmpF/STR Identifiler-TM and AmpF/STR Yfiler-TM kits ("Applied Biosystems", USA). As a result of the study, the skeletal remains of the boy from grave No2 were identified as actually belonging to the son of P.G. Demidov and E.N. Demidova with a probability of no less than 99.999999998%. whereas the girl buried in grave No4, was not the daughter of these parents.

Appel Botha: The abc of a three hundred year old divorce case.

In 1683 Maria Kickers and Jan Cornelitz got married in Cape Town. Today, 330 years later, the living patrilineal descendants of Maria's four sons, number in excess of 76,000 people. Curiously, none of them carry the surname Cornelitz - in fact, they are all called Botha and include former President P.W. Botha, general Louis Botha and Minister Pik Botha. The reason for this anomaly is also the reason why Jan got divorced from Maria in 1700. According to Maria's testimonies she did indeed have a long term relationship with Frederik Botha, but in her defence she claimed that her husband was impotent and that he actually encouraged her. Other witnesses, presumably prompted by Jan, gave testimonies that implied that Maria was in fact licentious. We combined haplotyping with the AmpFℓSTR(®) Yfiler™ kit with deep-rooting genealogies to show that Maria's first son was actually fathered by Ferdinandus Appel and that roughly half the living Bothas (38,000 people) actually descend from Ferdinandus Appel while the remaining three sons all stem from the same father, presumably Frederik Botha, and this implies that Maria's husband did not father any of her sons.

Bodies of science and law: forensic DNA profiling, biological bodies, and biopower.

How is jurisdiction transferred from an individual's biological body to agents of power such as the police, public prosecutors, and the judiciary, and what happens to these biological bodies when transformed from private into public objects? These questions are examined by analysing bodies situated at the intersection of science and law. More specifically, the transformation of 'private bodies' into 'public bodies' is analysed by going into the details of forensic DNA profiling in the Dutch jurisdiction. It will be argued that various 'forensic genetic practices' enact different forensic genetic bodies'. These enacted forensic genetic bodies are connected with various infringements of civil rights, which become articulated in exploring these forensic genetic bodies''normative registers'.

The genetics of innocence: analysis of 194 U.S. DNA exonerations.

This new analysis of 194 DNA exonerations, representing 171 criminal events, examines the types of evidence and DNA testing that have been used to free the victims of wrongful conviction. The types of DNA testing used to free the innocent parallels the growth of these techniques in forensic science. Short tandem repeat (STR) analysis now prevails (70%), though Y-STR analysis (16%) and mitochondrial testing (10%) are still used when STR analysis is not feasible, and the recently developed mini-STRs have been used for exonerations since 2008 (2.6%). The types of exculpatory evidence included intimate swabs (65%), clothing (53%), hair (13%), fingernail evidence (5%), cigarettes (3%), and other evidence. The most common factor associated with wrongful convictions was misidentification (75%), including misidentification by the victim (65%). False confessions (including admissions and pleas) were obtained in 30% of the cases, and informant testimony (including jailhouse and government informants) was used in 22% of the false convictions. Several types of invalid forensic science testimony were used to wrongfully convict in the 146 trials where transcripts or reliable forensic science data were available for analysis. Invalid testimony included serology (38%), hair comparison (22%), fingerprint comparison (2%), and bite mark comparison (3%). In 43% of the exonerations, the true perpetrator of the crime was identified through postconviction testing.

X-chromosomal markers: past, present and future.

Experience gained in clinical genetics led to the fundamental idea of using X-chromosomal markers in a wide range of forensic applications. To date more than 30 STRs have been established as forensic markers. Joint typing of very tightly linked STRs yields stable haplotypes, and can be used for establishing the relationship between distant relatives, such as aunt-niece pairs and cousins. For such applications the new ChrX typing kit Argus X-8 which is commercially available now is a powerful tool. This paper is aimed at presenting a brief survey of historical developments and discussing present and future aspects of forensic X-chomosomal testing.
