Woman accused of lying to cops in NH student death

DERRY, N.h. (WHDH) -- A second suspect arrested in the case of a murdered UNH student faced a judge Wednesday.

Kathryn McDonough sat silently in her red prison jump suit as Prosecutor Peter Hinckley explained to the court why she should be held on high bail for providing a false alibi.

“That the underlying crime here is the crime of murder, and that the victim’s body has yet to be recovered in no small part, because of Ms. McDonough’s active involvement in the conspiracy,” Hinckley told the court.

McDonough allegedly helped her boyfriend, Seth Mazzaglia, cover up the murder of Elizabeth Marriott, for which he is now charged, even though Marriott’s body has not been found.

The UNH student went missing in October. Dive teams and the Coast Guard scouted the waters around Portsmouth, New Hampshire. McDonough's lawyer said she is innocent.

“We are talking about an allegation of deception, not an allegation of murder, not an allegation that would suggest any kind of sinister act beyond what is referenced in these particular complaints that the court has before you,” McDonough’s attorney argued.

McDonough was released on $35,000 cash bail posted by her parents. The victim’s father told 7news that a second arrest in this case showed progress was being made.
