I think Jean Keir's height fell within the range or at least very close to it."
79 Bones Nos. 1 to 6 were sent to Dr Atchinson in Melbourne on 16 December 1991. Bone No. 7 was retained lest some mishap befell the other six ([581]).
80 Dr Atchinson was able to obtain only partial results from the DNA tests he carried out on the bones. He gave evidence to the effect that because he got results that could not be interpreted, he "felt the DNA had degraded to the extent it was not reliable" (T972). Dr Atchinson said that, in 1991, he had used an analysis technique developed in his laboratory which was not a commercial kit, and could analyse only one locus at a time (T967).
81 On 4 August 1992, the bones were delivered to Dr Van Daal in Adelaide. She was unable to obtain a complete DNA sample. Campbell AJ noted that the South Australian State Forensic Science Service "was using a monoplex rather than the later multiplex DNA testing system" ([760]). Dr Van Daal wrote to the officer-in-charge of the investigation, noting that further developments might assist at a later time and giving costings for such work (T1291-1293). No further work was done by Dr Van Daal, and the bones were sent back to Dr Atchinson in Melbourne in July 1994. He conducted further tests, the results of which were indistinct (T970).
82 Campbell AJ observed at [698] that no "continuity" challenge was made concerning the bones:
"It is relevant to note that the 'continuity' that is, the identity of the bones removed from Tregear and then examined in the various laboratories including the Armed Forces DNA Identification Laboratory of the United States was not challenged."
83 On 16 September 1997, the six bones were delivered to the Armed Forces DNA Identification Laboratory in the United States of America. Ms Nancy Ann Scibetta, from that laboratory, gave evidence at the trial by video link (T1178-1219). She said that the primary purpose of her position at the laboratory was to obtain mitochondrial DNA sequences from bones that were believed to be the remains of American soldiers who had died in World War II, the Korean War and the Vietnam War. Ms Scibetta said that her laboratory had developed special expertise in relation to bones or human remains recovered from theatres of war in difficult environments in terms of contamination, degradation and mixed human remains. It was her evidence that her laboratory was one of the best in the world for undertaking such work (T1180).
84 Ms Scibetta obtained a mitochondrial DNA sequence from two of the six bones which she had received, being the right big toe and the left patella fragment. They were the largest bones and came from opposite sides of the body ([704]). She explained the steps taken by her including measures taken to secure the bone samples against contamination (T1186, 1191-2). Having established that the two bones were consistent as having come from the same individual, or at least from an individual with a common maternal ancestor, Ms Scibetta extracted DNA from a blood sample given by Jean Keir's mother, Christine Strachan, and concluded that the mitochondrial DNA obtained from Mrs Strachan's blood sample was consistent with the mitochondrial sequence she had obtained from the two bones (T1187-1188). Ms Scibetta explained that an individual's mitochondrial DNA is inherited from the mother and is identical to the mother's mitochondrial DNA (T1184).
85 Ms Scibetta agreed that she did not necessarily know where contamination of samples such as bones and blood may have occurred from the time samples are obtained until they arrive in the laboratory. She agreed that the taped seals on the bone packets appeared not to be sticking and that there was dust, which she thought to be bone dust, in the bags (T1195, 1200). She said that she had considered the possibility that the existence of dust could be a potential contaminant. Ms Scibetta said that she was concerned about the possibility of contamination in every skeletal remains' case (T1201-1202). However, in relation to the sanding process that she conducted as part of the cleaning procedures prior to the extraction of DNA, Ms Scibetta stated that the possibility of contamination during the process was, in her experience and opinion, "not realistic at all" (T1218-1219).
86 Ms Scibetta also extracted DNA from the blood of Jean Keir's father, Gaspar Baan. DNA from two bones and the blood samples from Christine Strachan and Gaspar Baan were then given to Ms Demris Anita Lee, the technical leader of the Nuclear DNA Section of the Armed Forces DNA Identification Laboratory. Ms Lee gave evidence at the trial by audio-visual link (T1345-1370). She said the Nuclear DNA Section works on death investigations of the United States' armed forces, and its primary focus is recent death investigations where individuals are deceased from incidents such as aircraft mishaps, explosions, motor vehicle accidents and military attacks such as gunshot wounds or bombings, as well as mass disaster incidents involving commercial airline accidents and remains recovered from the ocean floor (T1347-8).
87 Ms Lee explained the difference between nuclear and mitochondrial DNA (T1348-9). She obtained complete nuclear DNA profiles of the two bones, which she identified as being those of a female (T1351-1353). Campbell AJ was satisfied beyond reasonable doubt that Ms Lee's procedures for obtaining complete nuclear DNA profiles of the two bones were appropriate and valid ([711]).
88 Ms Lee also obtained DNA profiles for Christine Strachan and Gaspar Baan from the blood samples which they had provided. Ms Lee concluded that, based on the DNA results, the bone samples were consistent with being an offspring of the two blood samples ([713]).
89 Ms Lee was cross-examined concerning the potential for contamination of the bones. She agreed that it was plausible that, if a specimen that had been denuded of any DNA had come into contact with another specimen such as a hand or even scalp or dandruff, the DNA could be transferred to the degraded specimen. She said, however, that in order to obtain the DNA profile from that bone, it would have to actually penetrate the bone because of the clinical procedures that had been undertaken, and that this was not possible from a touch or from dandruff (T1360).
90 After referring to the evidence of Ms Scibetta and Ms Lee, Campbell AJ concluded at [730]:
"I am satisfied beyond reasonable doubt that the DNA extracted by Ms Scibetta was, as she firmly stated, 'true to the bone'. I am also satisfied beyond reasonable doubt that the results obtained by Ms Scibetta and Ms Lee are valid and true reflections of the bones found at Tregear. I am also satisfied beyond reasonable doubt that the bones are those of a female, that their mitochondrial DNA is consistent with an offspring of Christine Strachan and that their nuclear DNA is consistent with an offspring of Christine Strachan and Gaspar Baan."
91 His Honour was conscious that these results alone did not establish that the bones were those of Jean Keir ([731]).
92 Although Campbell AJ considered that the procedures adopted in the United States of America and the results obtained "exclude any effect from earlier contamination should it have occurred", his Honour dealt with the defence submission at trial that contamination may have occurred. In particular, defence counsel submitted that testing done in Adelaide had raised issues which put in doubt the profiles established in the United States of America. Having considered the evidence as to tests which had earlier been conducted by Dr Atchinson and Dr Van Daal, his Honour concluded it was unlikely that the bones had been relevantly contaminated or that the test results excluded Gaspar Baan or Christine Strachan as potential parents ([776]). Following an examination of defence counsel's submission concerning the possibility of contamination based upon the evidence of Dr Atchinson and Dr Van Daal ([748]-[778]), Campbell AJ expressed the following conclusion at [779]:
"An examination of the events at Adelaide and Melbourne does not lead me to a different conclusion to that drawn as a result of the testing in America."
93 I agree with the Crown submission that the Appellant's complaint that the trial Judge ignored relevant DNA evidence, or ignored the possibility of contamination of the DNA evidence upon which his Honour ultimately relied, cannot be sustained in the face of Campbell AJ's detailed consideration of the expert evidence. Having undertaken that detailed consideration, Campbell AJ accepted the evidence given by Ms Scibetta and Ms Lee. His Honour saw and heard them give evidence and concluded that they were impressive witnesses ([701]).
94 Campbell AJ emphasised that an acceptance of the evidence of Ms Scibetta and Ms Lee did not, of itself, prove that the bones belonged to Jean Keir, with that question depending upon the statistical and other evidence in the case.
95 I have examined the evidence touching upon the question of possible contamination of DNA evidence, together with the analysis and findings of the trial Judge on this question. No error is demonstrated in his Honour's analysis. The findings made by Campbell AJ were clearly available. In my opinion, the findings are reasonable and are supported by the evidence. The Appellant has not demonstrated any basis for this Court to intervene.
96 I reject Grounds 1(c) and (d).
