Unique Spray Can Link Criminals To a Crime Scene

SmartTag is a traceable forensic spray that once sprayed on an offender, will stay on for months. Police can identify the unique code from just a speck of invisible material (except under UV light) left behind after it dries. This small town problem might not be the best use of the technology. The company also offers a 'forensic fog' that could be released in the doorway of a jewelry store or bank for example.
