Mazzaglia was also indicted for conspiracy to commit hindering apprehension or prosecution after state prosecutors allege that he and his girlfriend, Kathryn McDonough, 19, of Portsmouth took several steps to eliminate any physical evidence that Marriott was in his apartment on Oct. 9.

On April 10, a Rockingham County Grand Jury indicted McDonough of Portsmouth, for three felony counts of witness tampering, hindering apprehension or prosecution and conspiracy to commit hindering apprehension or prosecution related to Marriott's murder.

In May, the Dover Circuit Court released additional records that illustrated in great deal how Mazzaglia and McDonough allegedly disposed of Marriott's body and tried to cover up the crime.

Mazzaglia continues to held without bail at the Strafford County Jail in Dover.

The New Hampshire Attorney General's office had alleged that Mazzaglia strangled or suffocated Marriott on Oct 9 in his Dover apartment. Marriott had attended a class at the University of New Hampshire that night and headed to Dover to see some friends.

Authorities launched a massive search for Marriott's body that began in October, but no trace of her body has yet been found. Some of the areas where New Hampshire Marine Patrol and New Hampshire Fish and Game conservation officers focused their search were around Peirce Island in Portsmouth and off Fox Point in Newington.
