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."
