After emotional, graphic testimony, girlfriend back on stand for 3rd day of man’s murder trial

DOVER, N.H. – A New Hampshire woman is expected back on the witness stand for a third day in her ex-boyfriend’s murder trial, one day after describing in stark terms how he raped and killed a 19-year-old college student.

Kathryn McDonough spent a second day Wednesday under the questioning of prosecutors trying to prove that 31-year-old Seth Mazzaglia (muh-ZAYL’-yuh) killed Elizabeth “Lizzi” Marriott on Oct. 9, 2012, after she rejected his sexual advances.

McDonough said Mazzaglia choked Marriott with a rope then raped her. After she was dead, Mazzaglia and McDonough dumped her body in a river. It has never been found.

Mazzaglia’s lawyers have said that McDonough killed Marriott, of Westborough, Massachussets, during rough sex. His lawyers may get the chance to question McDonough when the trial resumes Thursday.
