DOVER, N.H. (MyFoxBoston.com) -- A jury found Seth Mazzaglia guilty of first-degree murder in the death of a 19-year-old University of New Hampshire student from Westborough.
Mazzaglia was convicted Friday in the Oct. 9, 2012, death of Elizabeth "Lizzi" Marriott. The 31-year-old was found guilty of first-degree murder in the October 2012 death of Lizzi Marriott. The jury found Mazzaglia guilty of knowingly or purposefully killing Marriott by strangulation, as well as killing her in connection with a felonious sexual assault.
Marriott's father, Bob, reacted after a long gruesome murder trial. He said even a conviction cannot console him or his family.
"We will always miss her and wonder what could've been," he said.
A sentencing date was not scheduled in court Friday.
During the trial, the state tried to prove that Mazzaglia killed Marriott when she rebuffed his sexual advances after a game of strip poker.
The defense maintained that Marriott died of suffocation during rough sex with Mazzaglia's ex-girlfriend, Kat McDonough, at his Dover apartment. McDonough is serving 1-1/2 to 3 years for witness tampering, hindering prosecution and conspiracy.
Prosecutors say the pair dumped Marriott's body into the Piscataqua River off Portsmouth's Peirce Island. It has not been found.
