DOVER, N.H. — A man charged with killing a University of New Hampshire student in October has waived his arraignment on murder charges.
Seth Mazzaglia was scheduled to appear in court Thursday after being indicted by a Strafford County grand jury.
Court documents charge the 30-year-old Mazzaglia of Dover with killing 19-year-old Elizabeth “Lizzi” Marriott during an attempted sexual assault on Oct. 9.
The indictments allege an extensive cover-up by Mazzaglia and his then-girlfriend, Kathryn McDonough, including using Marriott’s car to drive her body to Peirce Island in Portsmouth and dumping it in the Piscataqua River. Her body has never been recovered.
Mazzaglia is also charged with second-degree murder for showing “extreme indifference to human life.
