A judge says a 29-year-old martial arts instructor is accused of strangling or suffocating a University of New Hampshire student the day she disappeared nearly a week ago.
Seth Mazzaglia of Dover was ordered held without bail Monday on a second-degree murder charge in connection with the death of 19-year-old Elizabeth "Lizzi" Marriott of Westborough, Mass. Officials announced charges against him Saturday, after family and friends spent several days searching for her.
Mazzaglia was arraigned by video feed. He didn't speak. His next hearing is set for Oct. 29.
Marriott was last heard from Tuesday. Her car was found at the university.
Police have declined to say what led to Mazzaglia's arrest.
A prosecutor says authorities could spend several more days searching the waters off an island for Marriott's body.
Senior Assistant Attorney General Jane Young said Monday that while authorities believe Marriott was killed in Dover, the search remains focused on the waters around Pierce Island in Portsmouth.
She says Mazzaglia and Marriott knew each other but would not say what led to Mazzalgia's arrest.
