A jury has found Seth Mazzaglia, the 31 year old Dover man accused of killing and raping 19 year old UNH student Lizzi Marriott, guilty of all charges, including first degree murder.
After Marriott died, investigators found neither Lizzi Marriott’s body, nor any direct evidence of her murder. A guilty verdict in this trial would depend entirely on the credibility of the crime’s only eyewitness, Kat McDonough: the now 20-year old ex-girlfriend of Seth Mazzaglia.
A jury has found a Dover man guilty of the murder of 19-year-old University of New Hampshire student Elizabeth “Lizzi” Marriott.
Jurors in Strafford Superior Court deliberated for less than two days before finding 31-year-old Seth Mazzaglia, a community theater actor and karate instructor, guilty of first-degree murder by strangulation.
The jury found Mazzaglia guilty of additional charges related to Marriott's death – murder in the commission of felony sexual assault and two counts of conspiracy related to Mazzaglia’s efforts to tamper with and falsify evidence.
The defense has rested in the trial of Seth Mazzaglia, the 31 year old Dover man charged with raping and killing UNH student Lizzi Marriott.
Mazzaglia’s defense team rested after only two days, following 18 days of arguments from state prosecutors-- including extensive testimony by Mazzaglia’s 20-year-old ex-girlfriend, Kat McDonough. The defendant did not testify on his own behalf.
During the prosecution, the state argued Mazzaglia strangled Marriott. The defense countered that McDonough accidentally asphyxiated Marriott during sex.
Kathryn McDonough is a 19-year-old Portsmouth resident who has been arrested for giving a false alibi when questioned by the police as to her whereabouts at the time of the disappearance of UNH student Elizabeth Marriott.
A second arrest has been made in connection with disappearance and murder of UNH student Elizabeth Marriott. 19-year-old Portsmouth resident Kathryn McDonough has been arrested on charges of hindering apprehension or prosecution and conspiracy to hinder apprehension or prosecution.
Assistant Attorney General Peter Hinckley says McDonough was the girlfriend of Seth Mazzaglia who has been charged with Marriott’s murder.
The suspect charged in the death of UNH student Lizzi Marriott will be arraigned in Dover District court Monday.
At a press conference Saturday afternoon, authorities revealed they had information confirming the 19-year-old's death, but that they have yet to recover her body.
"This is still an active and ongoing investigation. We are, at this point only 24 hours in and, as you are aware, the search for her was ongoing for a period of about two days or so. But now, obviously, that has changed."
