---- — DOVER, N.H. (AP) — Prosecutors say a man accused of killing a University of New Hampshire student discussed framing and killing a witness in letters to his former girlfriend.
Seth Mazzaglia is charged with killing Elizabeth “Lizzi” Marriott, 19, on Oct. 9, 2012.
His former girlfriend, Kathryn “Kat” McDonough, has pleaded guilty to hindering prosecution, conspiracy and tampering with a witness.
In new court documents filed Friday, prosecutors said Mazzaglia, 30, sent letters to McDonough discussing framing two witnesses who had been called to Mazzaglia’s apartment after Marriott’s death and killing one of them. The state is seeking handwriting samples from Mazzaglia to compare to the letters. His attorney said Mazzaglia would provide them.
The letters also describe a dream of fleeing the country with McDonough to avoid prosecution, court documents said.
Prosecutors have said Mazzaglia strangled Marriott after or during an attempted sexual assault and dumped her body in the Piscataqua River near Peirce Island in Portsmouth. Her body has not been found.
Mazzaglia is being held without bond. His trial is scheduled to start in May.
A public defender representing him has previously declined to comment on the indictments.
