Dover man indicted for murder of UNH student

DOVER - The parents of Elizabeth "Lizzi" Marriott said the man indicted for the murder of their 19-year-old daughter has a "twisted sense of reality."

In a statement issued through their attorney, Bob and Melissa Marriott of Westborough, Mass., said Seth Mazzaglia, 30, of Dover fabricated the story that Marriott was killed during a consensual sexual act.

"What Mr. Mazzaglia, or any other, may suggest allegedly took place for a few minutes in a Dover apartment completely defies the reality of the 19 years of Lizzi's life as best attested to by her family, friends and community," the family said in a statement.

On Tuesday, indictments against Mazzaglia were made public in Strafford County Superior Court alleging that he strangled the University of New Hampshire sophomore before, during or after committing or attempting to commit felonious sexual assault.

Mazzaglia has been indicted on two counts of first-degree murder and one count of second-degree murder, based on the prosecution's different theories for the crime. He is facing a fourth count of hindering apprehension and/or prosecution.

Mazzaglia's girlfriend, Kathryn McDonough, 19, of Portsmouth was indicted earlier this month in Rockingham County Superior Court. Police say she hindered apprehension and/or prosecution and tampered with a witness.

Police allege that Mazzaglia murdered Marriott in his Dover apartment on Oct. 9 and then tried to cover up the murder by dumping her body in the Piscataqua River off Pierce Island in Portsmouth, lying to police about his whereabouts that night. He was arrested Oct. 13.

Marriott's body has not been found, despite an extensive search.

The Marriotts said it is their understanding the arrest warrants and affidavits may contain statements from Mazzaglia and others that are, in essence, "reprehensible, salacious and intentionally designed to suggest that Lizzi's murder was the accidental consequence of a bizarre, abnormal consensual act."

So far, those documents have remained under seal per a court order.

The Marriott family said Mazzaglia had several days from the time Marriott was murdered last October to concoct a "new reality" designed to help him.

"Common sense suggests that if one or two individuals accidentally injure another in a consensual act, the uninjured parties will immediately seek to assist the injured party or call 911. The fact that the defendants did neither in the instant matter is more indicative of a lack of consent by Lizzi concerning the circumstances of her death," the statement reads.

Marriott, a Westborough, Mass. native was living with an aunt and uncle in Chester while attending the University of New Hampshire.

Senior Assistant Attorney General Jeffery Strelzin said Mazzaglia's arraignment is scheduled for May 2 in Strafford County Superior Court.
