J.D. is the son of Bud Dean, the owner of a demolition company known as Big Bud Dean Construction. J.D. has moved seven times before, most notably to Dallas, Baton Rouge, Las Vegas, and Kansas before landing in Sherwood, Ohio. J.D.'s relationship with his father was severely affected by the suicide of his mother who knowingly walked into a building that J.D.’s father had rigged with explosives. It appears that his life and mental state were a lot more balanced prior to his mother's death. It isn't known if J.D. has killed before Heather Chandler’s death, though it is unlikely due to him appearing to be stunned and not having a plan on what to do next. Despite this, when Veronica asks if he had "done this before", J.D. does not give an answer. J.D. is a handsome young man with dark brown hair and hazel eyes, and his appearance is rather messy. J.D.'s usual outfit of choice is a men's flannel paired with a flannel or short sleeved button down that is covered by his trenchcoat. He wears one silver loop earring, but is seen wearing a diamond stud in most promotional material. When the movie takes place, J.D. is jaded and cynical. He makes an effort not to stand out at school, as we first see him sitting in the back corner of the cafeteria. At the start of the movie, he's usually rather calm, and is more of an observer, even after Heather Chandler's death. Once he and Veronica kill Kurt and Ram, J.D. is truly able to see what he can get away with, and becomes more unhinged throughout the rest of the film. He doesn't know what to do when things don't go according to plan, and his need to be right is unshakable. Years before the events of the movie, before his mother’s death, J.D. "seemed" to have had a pretty average and happy childhood.
