The man convicted of raping and killing a University of New Hampshire student who rejected his sexual advances is set to be sentenced to life in prison.

Family members and friends of 19-year-old Elizabeth "Lizzi" Marriott are expected to address 31-year-old Seth Mazzaglia (muh-ZAY'-lee-uh) when he is sentenced Thursday.

Mazzaglia was convicted in June in the death of Marriott in the apartment he shared with then-girlfriend Kathryn McDonough. McDonough testified that she lured Marriott to the apartment on Oct. 9, 2012 as a sexual gift to her domineering boyfriend. McDonough's already serving jail time.

McDonough initially said Marriott died while the two women had consensual rough sex. She later said Mazzaglia strangled Marriott after she twice rebuffed him. The pair threw Marriott's body in a river. It's never been found.
