May 28, 2014

Seth Mazzaglia is accused of killing UNH student Elizabeth (Lizzi) Marriott

The murder trial is set to begin for a New Hampshire man who police say raped and killed a 19-year-old college student then dumped her body in a river.

Thirty-one-year-old Seth Mazzaglia of Dover maintains that Elizabeth "Lizzi" Marriott died Oct. 9, 2012, during rough consensual sex. Marriott, of Westborough, Massachusetts, was a student at the University of New Hampshire and had been lured to Mazzaglia's apartment by his then-girlfriend, Kathryn McDonough.

Opening statements are scheduled to begin Wednesday in Strafford County Superior Court. Mazzaglia is charged with first-degree murder.

Marriott's body has not been found.

McDonough is expected to be the key witness against Mazzaglia. The 20-year-old is serving a 1-1/2 to 3-year prison sentence for hindering prosecution, witness tampering and conspiracy.
