Derry, NH, United States (4E) – A 19-year-old woman from Portsmouth, New Hampshire has been taken into custody Monday for her alleged connection to the disappearance and possible slaying of University of New Hampshire student, Elizabeth “Lizzi” Marriott.
According to prosecutors, Kathryn McDonough has lied about what she and her boyfriend, accused murderer 29-year-old Seth Mazzaglia, were doing during the time that 19-year-old Marriott was killed.
McDonough pleaded not guilty to two felony charges, conspiring to hinder apprehension and hindering apprehension. She is being held on a $35,000 bail.
Derry District Court Judge John Coughlin claimed even if McDonough post bail, she is prohibited to contact Mazzaglia.
Prosecutors said in court Wednesday the charges against McDonough were determined “from the defendant’s conduct, alone and in conjunction with Seth Mazzaglia, in the cover-up into the disappearance and homicide of Elizabeth Marriott on Oct. 9, 2012.”
McDonough showed up via video link at her arraignment.
Court documents stated she provided investigators a false alibi about her and Mazzaglia’s whereabouts on the night of October 9, 2012, and her denial regarding interacting with Mar¬riott that same evening.
New Hampshire Assistant Attorney General Peter Hinckley refused to talk about the details of the case because an active investigation is still ongoing.
Marriott, from Westboro, Massachusetts, was studying marine biology when she was reported missing after she failed to show up to meet friends.
Several days later, Mazzaglia, who lives in Dover, was charged with her murder.
Rescuers spent days combing the waters in and around Portsmouth for Marriott’s body, but nearly three months later, she still remained missing.
