Authorities say a woman charged in connection with the disappearance and death of a University of New Hampshire student lied about where she was.

Authorities say 19-year-old Kathryn McDonough of Portsmouth is the girlfriend of Seth Mazzaglia (mah-ZAY-lia), who is charged with second-degree murder in the death of Elizabeth Marriott. The 19-year-old Marriott was from Westborough, Mass., and was attending the University of New Hampshire.

Court papers say McDonough gave false statements to authorities about her activities on Oct. 9 and Oct. 12. Marriott was last seen Oct. 9.

The 30-year-old Mazzaglia is being held, and authorities are asking a judge to set bond for McDonough at $50,000. She's due in court Wednesday.
