As quickly as possible a CSI uses tape to lift any suspect fibres or hairs off the jacket for analysis. Then she puts the jacket in a plastic evidence bag and sends it off to a laboratory scientist who looks for things like bloodstains. After running appropriate tests, the scientist rebags the jacket and stores it ready for a possible appearance as a courtroom exhibit. If the scientist can’t find anything useful, the jacket will go into a warehouse to await the next scientific breakthrough that might produce useful evidence, such as extra-sensitive DNA testing.
