NH Man Seth Mazzaglia gets life for killing, raping college student

A New Hampshire man was sentenced to life in prison for the rape and murder of University of New Hampshire student Lizzi Marriott.

Seth Mazzaglia, 31, was also ordered to pay for Marriott's funeral and her family's mental health expenses. The 31-year-old must register as a sex offender and he will not be eligible for parole.

Mazzaglia spoke briefly, saying he didn't kill Marriott but he was sorry for the family's loss.

Mazzaglia was convicted in June of first-degree murder and other charges. The key witness was Mazzaglia's ex-girlfriend, Kathryn McDonough. She testified that she lured Marriott to their apartment in October 2012 as a sexual offering for her domineering boyfriend.

McDonough testified that Mazzaglia strangled Marriott after she twice rejected his sexual advances. The pair then threw Marriott's body in a river. It's never been found.
