By Associated Press Reporter The defense attorney for a man charged with raping and strangling to death a University of New Hampshire student spent his first day cross-examining the state's star witness trying to convince jurors she was possessed by imaginary characters she had created. Defense attorney Joachim Barth also asserted the witness, 20-year-old Kathryn McDonough, changed her story and shifted the blame from herself to defendant Seth Mazzaglia, her ex-boyfriend, just to get a reduced sentence. Mazzaglia is charged with first-degree murder in the October 2012 strangulation death of 19-year-old Elizabeth ‘Lizzi’ Marriott, of Westborough, Massachusetts. He has pleaded not guilty. Prosecutors say he and McDonough dumped Marriott's body in a river and it hasn't been recovered.

Prosecutors portray her as the sexual submissive, dominated in all aspects of their relationship by a man 10 years older than her, but Mazzaglia's lawyers say she was the dominatrix, a woman obsessed with finding another woman to dominate, and it was @placeholder who was her sexual slave.
