NH student's disappearance, death detailed in docs

By

DOVER, N.H. (AP) — The body of 19-year-old University of New Hampshire student Elizabeth "Lizzi" Marriot still has not been found — one of the many mysteries surrounding her killing and the couple charged in her death.

Thirty-year-old Seth Mazzaglia told investigators she died with a rope around her neck during a consensual sex act gone bad. Prosecutors are adamant she was murdered but so far won't say what evidence they have to back up their allegations.

Court documents detail the far-fetched alibis Mazzaglia and 19-year-old Kathryn McDonough initially gave to police in October — just days after the college sophomore disappeared.

He is facing first-degree murder and other charges. She is charged with conspiracy and hindering prosecution. Trial dates haven't been set.

The couple's attorneys haven't returned calls seeking comment.
