CI 121 - Cellular Records Analysis (Oct 2018, Mississippi)

This course is for officers, investigators, and analysts who encounter cell phone evidence that includes information external to the phone. Class concepts include instruction on how to request, read, and analyze call detail records from cellular providers, as well as how to plot cellular site locations to determine the approximate position of a suspect during a given period. No special hardware or software is required. However, this course focuses heavily on analysis; as such, a strong working knowledge of Microsoft Excel is highly recommended.

Students are provided with a free copy of the National White Collar Crime Center's (NW3C) PerpHound tool, which assists in the plotting of call detail record locations.
