Stu "Cobb" Cobbler was an unpopular Neptune High student who read gun magazines during class and dealt drugs. He also had a crush on Gia Goodman. Gia and her friends wanted to hit him up for drugs, but he managed to worm his way onto their party boat trip. That night, Susan Knight was found unconscious and her breathing was starting to waver. Everyone panicked. To calm everyone down, he told them that Susan would just sleep it out and that he'd seen it a hundred times. The next morning, however, Susan was dead. Stu suggested weighing her down with an anchor and throwing her body overboard. Gia, Luke Haldeman, and Carrie Bishop did so; Stu took a a photo of them in the act and used it to them to blackmail the group for years afterward.
