It may be a hoax, but an anonymous claim on Facebook has authorities at Old Dominion University investigating whether a student is trying to poison a roommate, WTKR News reported. The claim is on a "confessions" page for the university -- such pages exist for many colleges and students anonymous post about crushes or opinions. In this post, the student allegedly is putting items in the food of a roommate that will make her ill. Authorities announced that they have identified the individual who posted the claim and that no charges have been filed.
