With the increasing criminal investigations involving digital crimes, this three-day course will summarize the foundational principles of how to work an overall digital criminal investigation. This hands-on course will include examples of working cases involving social media, cloud-based servers, emails, and cellular devices. This course will help provide examples of how to communicate and request information from websites, cloud-based servers, and more entities from within the United States of America and other countries. This course will start with the reporting of the crime, preservation of evidence, acquisition of evidence (search warrants and/or consent searches), searching the evidence, and interviewing the suspect to help you build a concrete case file for prosecution. This course is primarily based on digital criminal investigations of child sexual abuse material (commonly referred to as child pornography), but the principles learned from this course will work for all digital criminal investigations.
