DOVER, N.H. (AP) — A New Hampshire prosecutor says the search for the body of a 19-year-old University of New Hampshire student has been suspended ahead of the arraignment for an actor and martial arts instructor who’s been charged in her death.

Senior Assistant Attorney General Jane Young said Sunday that a ground and water search on and around Portsmouth’s Peirce Island is expected to resume Monday. She says waters around the island were dangerous on Sunday.

Twenty-nine-year-old Seth Mazzaglia of Dover was charged Saturday with second-degree murder in the death of Elizabeth “Lizzi” Marriott. Marriott was from Westborough, Mass., and had been living with an aunt in Chester, N.H., and commuting to the university in Durham.

Young said Mazzaglia and Marriott knew each other, but she wouldn’t elaborate. Mazzaglia’s arraignment is Monday.
