DNA Sampling - Case Study ExampleThe natural law, because of legal concerns, eliminate to pursue this lead by acquiring samples from each of the thousands of persons of interest to it. The investigators second-best lead was the footage shot at a truck stop on the iniquity Falconio vanished. Bradley Murdoch was interviewed because his appearance and match with truck video, and passed everyplace for DNA sampling. But Murdoch provided an apparent excuse to the police and he was declared innocent.After six months, the Broome police pulled over Murdochs former flat mate and business partner, James Hepi. This was Task gist Regulus third big break, after the t-shirt DNA and the truck stop video. As a consequence of Hepis arrest, the police was offered the identity of the suspected killer of Falconio.In Australia, arrest and DNA sampling powers are typically restricted by a requirement that the police have objective investigation specific justification for using force. Murdoch was delib erately avoiding the Falconio investigators, so it was doubtful that, even if they found him, they can not touch him without his combine. At the same time Hepi was a first-time informant and, moreover, had much to gain (and nothing to lose) from pointing Murdoch. Without any grounds to trust Hepi himself, Taskforce Regulus took considerable efforts to verify claims made by Hepi. But every claim proved to be off-key. According to Senior Sergeant Megan Rowe, the head of Taskforce Regulus intelligence cell, Murdoch was the only man not eliminated out of the nominal by the public as men in the truck stop video, hot prospects identified by Rowe, and persons of interest to the investigation. Hepis tips were of some hope, but Taskforce Regulus ability to lawfully take a leak Murdochs DNA sample, once he was found, was in doubt. So Taskforce Regulus opted for a different way of testing Murdochs link to the t-shirt smudge. They approached Murdochs older brother, Gary, for his DNA sample. Garys consent for sampling yielded a partial DNA match. The partial match - to be expected if a blood relative of Garys was the source of the smudge - was certainly enough, in combination with the other information gathered by Taskforce Regulus, to objectively narrow the investigators suspicions to Murdoch himself. But, when Murdoch was located, two weeks later, none of the information gathered by the investigators was used, because of some legal concern, to prune either his arrest or the taking of his DNA sample.A phone call on 28 August 2002 was the final major break in the Falconio case. A mother and her daughter had been raped and kidnapped by Murdoch a week earlier. After this call Murdoch was arrested, and thus provided a new way for lawfully acquiring his DNA sample. However, the Australian jurisdictions require that the objective justification for a proposed DNA sampling should cover, not only who is sampled but also the investigative utility of sampling. So, to force Murdo ch to provide a DNA sample to investigate the allegations by the mother and daughter, the police needed reasonable grounds to expect that obtaining Murdochs DNA sample would manipulate a difference to that investigation.
