DOVER, N.H. (AP) — A New Hampshire man suspected of killing a University of New Hampshire sophomore more than a year ago is facing a new charge of planning an “armed and violent breakout” from jail.

Seth Mazzaglia was charged last year with first-degree murder in the disappearance and death of Elizabeth “Lizzi” Marriott of Westborough, Mass.

A grand jury this month indicted him on a charge of soliciting a man to help him escape from jail.

Mazzaglia’s public defender has declined to comment on previous indictments.
