Facebook touts over 2.2 billion monthly active users and unfortunately, a number of those are actually Facebook misusers. As social media platforms become integral to our lives, offenders have increasingly misused it to facilitate crimes, and as a means to assert power and control in the course of an intimate partner relationship. Investigators and prosecutors can identify, preserve, and present digital evidence from Facebook and other social media platforms in order strengthen cases, support victims, and hold offenders accountable for the full range of their criminal and abusive activity. This presentation will demonstrate how cyber investigations into Facebook can be used to reveal evidence of criminal activity, as well as evidence of the power and control dynamics of an abusive intimate partner relationship. The presenters will discuss theories of admission, rules of evidence, and case law, along with “real life” examples to demonstrate how to properly authenticate and introduce Facebook evidence in civil and criminal proceedings.
