deoxyribonucleic acid Sampling - Case Study ExampleThe natural law, because of court-ordered concerns, refuse to pursue this lead by acquiring take ins 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 night Falconio vanished. Bradley Murdoch was interviewed because his appearance and match with truck video, and passed over for deoxyribonucleic acid sampling. But Murdoch provided an appargonnt excuse to the police and he was declared innocent.After six months, the Broome police pulled over Murdochs former flat mate and duty partner, James Hepi. This was Taskforce 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 particularized justifica tion for using force. Murdoch was deliberately avoiding the Falconio investigators, so it was doubtful that, even if they found him, they can non associate him with forbidden his consent. 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 grand to trust Hepi himself, Taskforce Regulus took considerable efforts to verify claims made by Hepi. But every claim turn out 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 nominated by the public as men in the truck stop video, hot prospects determine by Rowe, and persons of interest to the investigation. Hepis tips were of some hope, but Taskforce Regulus ability to licitly take Murdochs DNA savour, 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 Murd ochs 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 self-possessed 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 justify 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 plundered 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 als o the investigative utility of sampling. So, to force Murdoch 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 make a difference to that investigation.
