"He has admitted to being 'obsessed' with her, has stated his intention of removing his 'enemies' , has stated his intention of purchasing a weapon, and has threatened to kill himself and to engage in dramatic actions to get her attention," the court documents claim. According to the papers, Max rooms with Klein, who says he is a celebrity photographer. "Over the past six weeks, the defendants have engaged in an accelerated effort" to contact Duff, including visits to her neighborhood, her mother's home, Madden's neighborhood, a venue in Hollywood where Madden and Good Charlotte performed, and direct calls to Duff's manger, the documents claim. Los Angeles police detained Max outside of Good Charlotte's concert after the band's security personnel alerted authorities to the pair's presence, according to the papers. Duff and Madden are requesting that Max and Klein stay at least 100 yards away from them, Duff's sister Haylie, 21, her mother Susan, 53, and Madden's twin brother Benji.
