This morning's addition to the forensics simulator was a Comparison Microscope, specifically for the purpose of identifying finger prints (although I'm not sure it's actually used for this purpose).
It is now possible to assign fingerprints to objects in the world, which can be retrieved while wielding the correct tool. Below we have the murder weapon hidden in some bushes. A print taken from this can be compared with one taken from the hand-prints in the bathroom.
Shown below is the comparison microscope itself. Fingerprint samples can be dropped onto the left or right location. If the print is on file then the corresponding record appears on the panel behind; and a match between two samples is also flagged.
