In the fall of 2012, Lizzi Marriott was a new student at the University of New Hampshire, majoring in marine biology. She moved out of her home in Massachusetts that she shared with her parents, Bob and Melissa Marriott.
"She got into UNH," Melissa says of Lizzi. "She was on her way."
Lizzi Marriott's car was found in this parking lot in the UNH campus. The Marriott's would search tirelessly for their daughter, and received the help of friends, family and local and national police forces.
During his 11 hour interview with police, Seth Mazzaglia went with detectives to Peirce Island in Portsmouth, N.H, where he told them he dumped Lizzi's body into the Piscataqua River--famous for its strong tides and currents.
The search for the missing UNH student now became a search for her body.
