Reporting Violations and Plagiarism

Description of the Problem

You are a faculty mentor for a graduate student in your department. The student is taking some classes in another department that requires written essays. He asks you to read his essay before he submits it. You routinely Google his work and discover that large parts have been lifted, verbatim, from the web with no quotation marks or citations.
