DOVER, N.H. (MyFoxBoston.com) – A Dover man charged with killing University of New Hampshire student Elizabeth Marriott in October has allegedly told police he accidentally killed her during the course of a consensual sex act involving erotic asphyxiation.
Seth Mazzaglia, 33, initially lied to police about his alleged Oct. 9 encounter with Marriott saying he believed someone else had physically strangled Marriott while he was not in her presence; however, later, he reportedly came clean regarding his involvement saying her death was the result of a BDSM sex act gone wrong, reports Foster's Daily Democrat.
The statements Mazzaglia reportedly made to police Oct. 12 were unsealed Monday.
During the act, Mazzaglia said he put a rope around Marriott's neck and applied pressure. He then said Marriott suffered what appeared to be a seizure. He checked her body for pulse in multiple locations and placed a plastic grocery bag over her head.
According to the affidavit obtained by the newspaper, Mazzaglia told police he was playing strip poker with Marriott and his girlfriend on Oct. 9 when the three of them began talking about BDSM. The conversation "eventually led to a consensual sexual encounter involving autoerotic asphyxiation."
In the document, Mazzaglia also described how he and McDonough disposed of Marriott's body. He told investigators he threw her body off of a small cliff in Portsmouth into the Piscataqua River. He also allegedly threw her cell phone into the water.
Mazzaglia said he and McDonough then traveled to several other locations, including a Residence Inn in Portsmouth and UNH, to dispose of materials they used to conceal the act. He said they arrived back at his apartment at about 6:15 a.m. and discarded the clothes they had been wearing.
Mazzaglia is facing first- and second-degree murder charges in connection with Marriott's death.
