Elizabeth Lizzi Marriott, 19, a University of New Hampshire student, was last seen on October 9, 2012. She attended an evening chemistry class and sent a text around 8:55 p.m. saying she was on her way to visit a friend named Kat but never arrived; her tan 2001 Mazda Tribute was later found abandoned on the UNH campus.

Authorities came to suspect foul play after a few days. On October 13, 2012, 29-year-old Seth Mazzaglia of Dover was arrested and charged with her murder. Prosecutors say Mazzaglia strangled Lizzi after she resisted his advances; he maintained her death was an accidental outcome of a sexual encounter. Mazzaglia’s then-girlfriend Kathryn McDonough, who had worked with Lizzi, later testified that the two disposed of Lizzi’s body by dumping it into the Piscataqua River. Her body was never recovered and is believed to have been washed out to sea.

Does anyone have information about Lizzi’s movements on the evening of October 9, 2012, or recall seeing her tan 2001 Mazda Tribute on campus that night?
