Lawyer to Mazzaglia ex-girlfriend: 'You have no appreciation for Ms. Marriott's life'
McDonough, 20, said that before Mazzaglia’s murder trial, she’d long been unable to tell the truth about what happened to UNH student Elizabeth “Lizzi” Marriott on the night of Oct. 9, 2012.
Mazzaglia is facing first- and second-degree murder charges in the death of Marriott, a 19-year-old from Westborough, Mass. McDonough testified last week that she was sitting next to Marriott when Mazzaglia began strangling her from behind with a rope, and that Mazzaglia, 31, then raped Marriott’s limp body.
McDonough acknowledged Thursday that she initially lied to investigators, Barth’s legal team, Mazzaglia and others. She said that in attempts to protect Mazzaglia, she told those lies and created a story about rough sexual contact that led to the “accident” of Marriott’s death.
McDonough is serving a 1½- to three-year prison term after pleading guilty last July to charges including witness tampering and hindering the investigation, as part of a plea agreement. She has testified that she helped cover up the murder and rape of Marriott, whose body has never been found.
“You described to us that the kind of harness you put on Liz Marriott would make it hard to breathe if you pushed your head forward, correct?” Barth asked.
“You described the encounter with Liz Marriott to us on the 15th and confirmed it again on the 17th?” he asked.
“You described, literally, the feelings you had during this act of sexual domination,” Barth pressed.
“That was the way I described something that didn’t actually happen,” McDonough said.
“Does that make you a really good liar then, or a better liar now?” Barth asked.
The trial in Strafford County Superior Court resumes today at 9:30 a.m.
