Summary

With the rise of electronic evidence and the likelihood that the crimes you’re investigating are conducted with or supported by the use of mobile devices, the Internet, or cloud-based applications, preservation letters provide a means to prevent the destruction of electronic records and buy an investigator time to retrieve and analyze potential evidence. This course focuses on the basics of preservation letters – what they are, their purpose, language to include, how to locate contact information, and how to submit them.
