While going through a particular student's safe assign report, suspected entries marked with a percentage (how much it overlaps with a source or another paper) match with another student's paper. But it just says "another student's paper." I'm sure its a paper from within the school, but it's not from within the same class. Is there anyway to find out who wrote this other paper, or better yet, get access to this paper to see how much it actually overlaps? I'm concerned the student's paper that I'm grading used every single reference used in the other paper, stole the title of the paper, and also sections of the paper.
