forensic laboratories? what are the different types of departments you get in a Forensic Lab?

Departments and subsections might include "questioned documents" (e.g., watermarks, inks), forensic entomology (studies of insects to establish time of death), odontology (teeth), anthropology (physical characteristics of remains)....I even heard of forensic ACCOUNTING, which is basically "let's see where the money went", used to help establish motive for a crime, IIRC.

Have you Googled this, or perhaps tried something like the FBI or your state Bureau of Investigation site? There may be a lot of good hits there....
