PORTSMOUTH, N.H. (AP) ? A 19-year-old woman charged with lying about her whereabouts the day a University of New Hampshire student was killed is free on bail.

Kathryn McDonough of Portsmouth appeared in court Wednesday.

She is charged with hindering prosecution and conspiracy in connection with the disappearance and death of 19-year-old UNH sophomore Elizabeth Marriott, of Westborough, Mass.

Prosecutors say McDonough lied when she said she and 30-year-old Seth Mazzaglia, of Dover, had no contact with Marriott on Oct. 9, the day she disappeared.

Prosecutors say Mazzaglia, who is charged with second-degree murder, suffocated or strangled Marriott.

McDonough was arrested Christmas Eve.

She was released from jail Monday after posting $35,000 bail.
