This two-part webinar series presented by the Denver District Attorney’s Office, in partnership with AEquitas, explores the scope of data available from sources of digital evidence and strategies on how such data can effectively be developed with forensically-sound practices. Presenters discuss theories of admission, rules of evidence, and “real life” examples to demonstrate how to properly authenticate and introduce digital evidence in court proceedings. Part I of the series explores the different types and sources of electronic data that are available to investigators; how such data can be properly collected, regardless of whether it is in a physical device or electronic records; and methods to facilitate searching and seizing data.
