为什么南威尔士警察使用Leica Geosystems Blk360进行激光扫描主要犯罪现场

The journey to buying a forensic laser-scanner

罗素·加德纳（Russell Gardner）是南威尔士警察总部联合科学调查部门的主要法医成像官，该部门还为格温特警察提供服务。该部队一直在犯罪现场使用手动测量技术和传统视频/摄影，但可以看到激光扫描可以带来的好处。拉斯解释说：“因此，对于一些主要案件，我们为带来外部服务而付出了代价 - 但这永远不会成为长期解决方案。”

长期捕捉的好处

根据拉斯·加德纳（Russ Gardner）的说法，“我们对系统的使用有助于我们避免打扰证据，我们可以在清除或处置任何东西之前永久捕获整个场景。然后，即使几年后，我们可以随时回到数据，以查看床的高度或证人的观点。这确实很重要，因为当您在现场时，您可能不知道几个月来可能会出现哪些问题。

作为法医成像专家，我们越来越多地改变了案件的结果，这也可能意味着对受害者或亲人产生积极的影响。

Using scan data can be important. We’re there at the very start of the case, gathering the evidence, and then again at the end when we present and interpret it in court. It’s a privilege to be involved in the whole journey, rather than just part of it.”

Scenario 1 – A buried victim

一个失踪的人变成了一个谋杀案件时body was found in a makeshift grave. Russ’ team scanned the burial area both before and after the body was removed, unsure what the data might offer but wanting to capture the best possible evidence as fully as they could.

包括法医考古学家在内的专家能够推断出坟墓是如何被挖出的以及嫌疑人在挖出和铲土壤时所处的位置。

The scan data was key in producing a very accurate visual record of the grave shape and structure, which is often difficult to see from 2D scaled drawings, photographs and plot diagrams.

法医考古学家说,扫描工作very well on this case and it does a great job of recording the scene to scale with relative ease, speed and most importantly to me, with no intrusion to the grave or what it contains. The videos you produced of the fly through were exceptional and really assisted in the presentation of the evidence.’

Senior Investigating officer DI Andy Miles said, “As the senior Investigating officer in this case I would have attended at the scene to view the landscape and deposition site for myself. Where this technology has a significant impact is for the benefit of others. The jury at the subsequent trial-obviously they would not have the benefit of being there themselves, the trial would have been many months later. I have no doubt that showing this emotive footage within the courtroom setting to the jury and the defendant has had the knock on effect of the defendant offering a guilty plea. Technology such as this cannot be underestimated in such cases”.

方案2 - 刺伤的车内谋杀案

闭路电视录像显示，在停在房屋外的一辆车辆中，深夜刺伤了。但是，天黑了，以至于很难解释镜头。因此，第二天，Russ的团队使用该系统创建了场景的“鸟眼”，将车辆与CCTV相机及其视野范围相关。

尽管犯罪嫌疑人被其他手段逮捕，但扫描数据为案件中有关的所有人（尤其是陪审团）提供了重要的确认和理解。导致了信念。
