New court documents say that a girlfriend of the 28-year-old man accused of kidnapping a University of Illinois Chinese scholar, that she was so nervous while secretly recording him on behalf of the FBI, that she fainted at least once in front of him. The account came in a pretrial motion, which was filed by Brendt Christensen’s lawyers on Monday in Urbana. It asked that the judge exclude the June recordings for the upcoming trial for the kidnapping of 26-year-old Yingying Zhang. She is presumed to be dead. The girlfriend described to agents that her heart was pounds so much that she “went into shock and passed out while attempting to talk to Christensen.” Among the places that she recorded him at a vigil for Zhang’s family, friends and supporters, amid the search for her. He was then arrested the very next day.
