Meanwhile, officials expect to decide Monday the next step in the search for Marriott's body.
Marriott, a marine biology major, was last heard from on Tuesday. Her cellphone was last used that night and her car was found at UNH.
Marriott's family says she met Mazzaglia last summer when both were working at a Target store.
Police declined to say what led to Mazzaglia's arrest. They said they have credible information leading them to believe Marriott's dead, but wouldn't elaborate.
