Dois ataques terroristas nacionais documentados com Leica ScanStation

德克萨斯州警察局基林（Killeen）使用Leica Geosystems 3D扫描仪在犯罪现场映射两起臭名昭著的备受瞩目的事件中起着至关重要的作用：FT。胡德射击和自杀飞机坠毁进入德克萨斯州IRS大楼。

得克萨斯州的基林（Killeen） - 2009年11月5日下午1:30之后，在德克萨斯州胡德堡（Fort Hood）的美国陆军基地的警察局警察在该职位上警告了一名活跃射手的地区执法机构，这可能是不止一个 - 导致了一名现场射手在大规模伤亡中。在几分钟之内，基林警察局局长丹尼斯·鲍德温（Dennis Baldwin）是该邮政直接附近的130,000个城市，成立了事件指挥中心，并联系了胡德堡警察提供帮助。

鲍德温酋长在基林警察局任职27年，对可怕的罪行并不陌生。十八年前，一名狂热的男子撞到了附近的卢比餐厅，然后他用两把半自动手枪杀死了23人，并在自杀之前又伤了20人。这项事件是美国历史上一名枪手最致命的枪击事件，直到2007年弗吉尼亚理工大学大屠杀32名学生和员工。

鲍德温解释说：“我们中的几个人经历了卢比的大屠杀，”我们知道人们在现场正在经历什么。在那些情况下，起初存在很多混乱和错误信息。我们知道最好的事情是伸出援手，但不要妨碍您。”

The Fort Hood authorities requested a tactical response team and assistance in stopping traffic coming onto the post. The Tactical Response Unit responded to assist in securing the area and search for any additional suspects, while surrounding agencies assisted KPD in traffic management near the post’s entrances. Fort Hood is one of the largest military installations in the world, covering 350 square miles and serving as home to 55,000 military personnel. Shortly thereafter, the base’s Criminal Investigation Division made a second request of Chief Baldwin: to send his department’s forensic team with its recently acquired Leica Geosystems’ 3D Laser Scanner.

鲍德温说：“我们是德克萨斯州唯一拥有扫描仪的第一个，也是当时唯一的机构，而霍德堡警察已经意识到了其非凡的能力。”“我们立即部署了我们的团队。”

“我们在枪击事件发生后的一个小时内就在那里，”带领球队的侦探基思·德罗兹（Keith Drozd）（与罗斯的押韵）。“这是一个非常高的压力环境，人们到处都是。当然，我去过的最大的犯罪现场是足球场的六座建筑物，几乎是建筑物两边的停车场。外面到处都有医疗用具，地面上到处都是鲜血。窗户破了，人们把椅子扔在玻璃杯上逃脱。死者仍然在建筑物内部，但射手也来到了外面并枪杀了人们。一些受伤的人仍在接受治疗。”

Drozd和他的团队上班，利用扫描仪的强大的远程测量能力，在建筑物内部和外部进行扫描。他们的映射工作至关重要。尽管很快负责调查的联邦调查局（FBI）有几次激光扫描仪，但有两名在伊拉克使用，而其他联邦调查局则回到了弗吉尼亚州的联邦调查局总部。区域机构调查人员只有一个总站，他们将其带到现场。

“The next day, after we wrapped up our scans, we met with an FBI computer technician,” Drozd recalls. “He works a lot with CAD programs (Computer Assisted Design) and we were able to download to his computer all the scan data we had collected. We later learned that (with a technical assist from Leica Geosystems) the FBI was able to generate an impressive presentation that they showed to President Obama during a White House briefing. It was an honor to have given them that data to show the president.”

Drozd credits the Leica ScanStation’s ease of use for giving his team confidence even while working in a highly charged environment under a national spotlight. “I can’t imagine how hard documenting a crime scene like Fort Hood would be without this Leica scanner. Using only tape measures, a total station and a plumb bob would have taken us days. With the ScanStation, even though your anxiety level is high and there’s immense pressure to get it right, you know this is a very easy instrument to operate.”

Chief Baldwin concurs: “The Fort Hood shooting, with its massive crime scene, really showed us what tremendous capabilities the Leica ScanStation has. The agencies in our area quickly came to realize how important the technology is to forensically mapping these very difficult crime scenes."

在胡德堡枪击事件发生三个月后，基林警察局的法医团队再次被要求协助一次引人注目的事件，这是德克萨斯州奥斯汀的这一事件，位于基林以南75英里处。2010年2月18日，上午9:56，一家自杀，心怀不满的纳税人安德鲁·约瑟夫·斯塔克（Andrew Joseph Stack）故意将他的派珀·达科塔（Piper Dakota）飞机驾驶到一个七层楼的办公楼，其中包含内部税收服务现场办公室。碰撞引起了巨大的火球和爆炸，这导致后来猜测Stack在起飞前用航空燃料的桶取代了飞机上的乘客座椅。撞车事故杀死了Stack和一名IRS办公室工作人员，并重伤了13人，两人认真对待。Drozd侦探和三名侦探立即做出了反应。

碰巧的是，联邦调查局的重大事件犯罪现场调查部门在其隔壁大楼的区域办公室举行了一场员工会议。首席调查员熟悉基林警察局在胡德（Fort Hood）事件期间与莱卡（Leica）3D激光扫描仪的出色工作，他立即与KPD联系，并要求他们的法医团队和扫描仪来到坠机现场。Drozd侦探和三名侦探立即做出了反应。

到达现场，Drozd再次发现自己在被媒体马戏团包围的聚光灯下工作。“有很多新闻卡车，到处都是卫星菜肴，记者和摄制组。建筑物的整个前部都被打碎，吹来并燃烧。我们在碎片田的外围设置了大约七十码，深六十码处。从建筑物吹来的档案柜，办公家具，玻璃和残骸都散落在各处。”

Drozd’s team was soon joined by Austin resident and Leica Geosystems trainer Karen Hughes, who lives just 15 minutes from the IRS building and who volunteered to provide any assistance that might be needed during the scanning. The crime scene they faced this time differed significantly from the Fort Hood setting. Here the primary focus was a large gaping hole in the front of the building between the third and fourth story.

“Just behind us was a large dirt embankment, maybe thirty feet high,” Drozd explained. “What had happened was the plane actually hit the embankment first and exploded—the front end of the aircraft bounced up and into the window while the back end hit a large steel support beam. We were facing a forensic scene unlike any we’d had before.”

“There was no possible way that investigators could have mapped the damage to the side of that building with traditional measuring tools, let alone even accessed it,” Drozd explained. “The collision opening was three stories above us and no one was allowed inside until engineers had determined it would not collapse. We worked our way across the building front and captured multiple scans. The Leica ScanStation performed flawlessly.”

扫描扫描仪的数据文件和奥斯丁犯罪现场的数据文件都是两种事件中收集的证据的重要因素。在胡德堡枪击案中，一名袭击者陆军少校尼达尔·哈桑（Nidal Hasan）被指控。该案件尚未进行审判，但左撇子扫描数据文件将用于生成许多展览，以便在该法院进行。

“Regardless of what crimes our detectives are responsible for processing,” explained Chief Baldwin, “It’s nice to know that the Leica ScanStation is capable of handling it. The system is easy to use and quickly provides forensic mapping and allows detectives to virtually ‘return’ to the crime scene for investigative follow-up. My detectives believe it is truly a remarkable system. Moreover, there’s no better method to present a case in a court room.”

While the Killeen Police Department has used its Leica 3D scanner on numerous major crimes, its successful experience deploying the system in the extremely challenging crime scene environments presented by the Fort Hood shooting and the Austin plane crash provided a powerful validation of the Leica ScanStation’s formidable capabilities. “Unfortunately in today’s society, we are seeing horrific crimes committed,” Chief Baldwin concluded. “These crime scenes can be very difficult to process. Having a system that can forensically measure these scenes is invaluable to the law enforcement mission. I believe other police chiefs are realizing this
事实，也是如此。
