After Andy is killed in a manner reminiscent of Jeffrey Dahmer, M.J. deduces the killer to be Peter Foley. After leading a failed attempt to catch Foley at his house, M.J. reaches the house of Helen, M.J. discovers that he has kidnapped her and left a video to M.J. and asked him to guess where he has taken Helen. M.J. guesses and heads back to the scene of Daryll Lee's attempt at killing her – the restroom of the lecture hall. Once she gets there, M.J. finds Helen bound, hanged and gagged in the same manner that Cullum did before, but she is ambushed and shot by Foley, rendering her unconscious. As Foley prepares to kill M.J., Helen desperately attempts to save her by ruining Foley's carefully replicated crime scene the only way she can – by attempting to hang herself. Foley panics and cuts Helen down, and Helen is able to get away and escape to the building's roof. Her agoraphobia kicks in again, and Helen finds herself cornered. Accepting her fate, she turns to face Foley. However, just as he is about to kill her, M.J. shoots him in the Brachial nerve, giving him one last chance to surrender. When he pulls his gun back on her, however, she shoots him until she kills him with a headshot.
