Abstract
Automated ballistic identification systems have enabled forensic examiners to obtain convictions as well as solve crimes. Over the past decade two automated search and retrieval systems, DRUGFIRE and IBIS, have obtained widespread usage and recognition in both the United States and foreign forensic laboratories. Both are multimedia systems integrating a forensic database with video, audio, digital imaging, and telecommunications. Both provide the capability to image and acquire data from both bullets and cartridge cases, and then store such information in a searchable database. Both systems greatly aid examiners by allowing them to readily sift through the numerous images of bullet striations. They have proved capable of matching the striations exhibited on crime scene bullets to those fired by suspect weapons in a matter of hours and even minutes. However, there has been a trend in both the State and Federal courts that requires a much more stringent level of scrutiny on the assertions made by forensics professionals. The development of a three dimensional ballistics analysis system named SciClops provides information that is undetectable through visual analysis, either by standard comparison microscopes or through 2D imaging systems. In addition to being far more accurate, the 3D system can also further reduce the time it takes to analyze striations. The technology is being developed to provide 3D ballistics imaging analysis via the Web, which could enable any computer with a Web browser to become an analysis station. Bullets from crime scenes around the country can be compared to thousands of murder weapons, thus allowing the matching of previously unrelated bullets and weapons.
