Defense hits girlfriend's deal in murder trial

DOVER, N.H. (AP) — The defense lawyer for a man charged with raping and killing a University of New Hampshire student has spent his first day cross-examining the state's star witness by trying to show she was possessed by imaginary characters she had created.

Defense attorney Joachim (JAHK'-ihm) Barth also said 20-year-old Kathryn McDonough changed her story and shifted the blame from herself to her ex-boyfriend — 31-year-old Seth Mazzaglia (muh-ZAYL'-yuh) — just to get a reduced sentence.

Mazzaglia is charged with first-degree murder in the October 2012 death of 19-year-old Elizabeth "Lizzi" Marriott of Westborough, Massachusetts. Prosecutors say he and McDonough dumped her body in a river. It has not been recovered.

McDonough testified Thursday the imaginary characters she began creating during childhood were just "masks" to help her get through difficult situations.
