Course Description

Determining the location of an individual at a specific point in time can make or break a case. You can use location data to present an alibi defense, discredit a witness or party, show how long someone was on the road prior to a crash, establish where a digital contract was signed, and more. In this program, Brian Chase, consultant, expert witness, and adjunct professor of law, will teach attorneys how to find, understand, and use location data from a variety of sources. It will explore cell site location information (CSLI), GPS data, location information from cell phones, and even non-traditional sources of location information such as the Internet of Things or Smart Home devices. 

Learning Objectives:

  1. Obtain and map cell site location information 
  2. Identify common location data errors made by experts
  3. Explore the limitations of cell site location information and how the data can be misused in court
  4. Find alternative sources of location data, including GPS and Google Timeline data, to contrast cell site location information, or use as independent sources of location history
  5. Use non-location specific digital evidence to develop location information in litigation
