A 29-year-old Dover man has been charged with murder in the death of University of New Hampshire student Elizabeth Marriott, the Attorney General's Office announced this afternoon.

Seth Mazzaglia will be arraigned on a charge of second degree murder on Monday in Dover District Court.

During a press conference at the Dover Police Station on Saturday, Assistant Attorney General James Vara would not comment on why Portsmouth Police are searching in the area of Peirce Island, only that the search to locate Marriott's body continues.

"We have information that we are investigating at this time," he said.

Vara said Marriott's car has been located in a parking lot at UNH, and that students there are in no danger. He said Marriott and Mazzaglia knew one another, but would not comment on the extent of their relationship.

According to his website, Mazzaglia lives on Mill Street in Dover. Police searched a Mill Street apartment building on Friday, searching a dumpster located nearby.

Mazzaglia's website also says he is "an experienced Actor, Writer and Fight Choreographer" who has worked in theatres in Southern New Hampshire for many years, most recently in the Garrison Players' production of "The Miracle Worker."
