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

Russell Gardner is principal forensic imaging officer at the Joint Scientific Investigations Unit at South Wales Police Headquarters, which also provides services to Gwent Police. The force had been using manual measurement techniques and traditional video/photography at crime scenes, but could see the benefits that laser scanning could bring. “So for a few major cases we paid to bring in an external service – but that was never going to be a long-term solution,” explains Russ.

“The BLK360 has worked well in our crime-scene investigations.” Russ Gardner, South Wales Police

The benefits of long-term scene capture

According to Russ Gardner: “Our use of the system helps us avoid disturbing the evidence, and we can permanently capture the whole scene before anything is removed or disposed of. We can then go back to the data any time, even years later, to see the height of a bed or a witness viewpoint. This really matters because when you’re at the scene, you can’t possibly know what questions might come up several months down the line.

As forensic imaging specialists, we increasingly make a difference to the outcome of a case, which can also mean making a positive difference for the victim or their loved ones.

使用扫描数据可能很重要。我们在案件的一开始就在那里，收集证据，然后在我们在法庭上介绍和解释时再次出现。参与整个旅程是一种荣幸，而不仅仅是其中的一部分。”

Scenario 1 – A buried victim

A missing person case became a murder case when a 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.

A Forensic Archaeologist said, ‘The scan did work 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.’

高级调查官员迪安迪·迈尔斯说,“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”.

Scenario 2 – An In-vehicle murder by stabbing

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。
