Tools
When dealing with Forensics, there are two major tools that you are utilizing, the Forensic Analyzer and the Forensic Pad.
Forensic Analyzer
A gadget, that when clicked on an object, allows you to print out a paper with the fingerprints and fibers. Remember to account for the fibers and fingerprints of the person who turned it in, yourself, security officers and any others.
Forensic Pad
A pad that allows you to identify the fingerprint IDs of a person. Remember to take off their gloves!
Whilst some stations do have consoles that have a list of crew members on station with their fingerprints, it is more reliable to use the forensic pad.
Fibers and Gloves
If you aren't given a fingerprint on the Forensic Analyzer, you can still help identify suspects with fibers.
It is to note that fingerless gloves leave fingerprints AND fibers.
