Abstract
The objective of the talk is to provide the participants with an overview of the scientific investigation techniques applied to a crime where firearms are used. The talk would be a discussion on different types of applications for forensic science to crime investigation, including the use of Microscope for ballistics comparison and testing of firearms for muzzle to target distance determination. It would also show different types of evidences collected from a shooting scene, their examination and interpretation. Finally how these results could be used for crime scene reconstruction.
簡單介紹槍械法證科學及檢測技術，概括總覽用於罪案偵緝工作上的科學槍械鑑證技術。講座於開首會介紹槍械如何被使用於罪案中，第二部份會討論不同的罪案槍械偵測技術如何應用於上述罪案當中。此環節中講者會講述顯微鏡下彈道比較方法及槍口與目標的射程距離，並展示相關彈道場景、檢測及偵查工作圖片。最後會講述檢測所得結果如何應用於重現犯罪場景。
