McDonough lawyer: 'Nothing but regret' in Marriott murder
Affidavits supporting McDonough's arrest on Dec. 24 were unsealed in 10th Circuit Court in Portsmouth on Tuesday in response to the state declaring that the records no longer needed to be impounded.
McDonough's live-in boyfriend, Seth Mazzaglia, is charged with Marriott's murder - the details of which remain a contentious point of debate for the victim's family.
Mazzaglia, 30, claimed that Marriott died at his Dover apartment during a consensual group-sex act with McDonough that involved asphyxiating Marriott's neck with a rope, according to police. A lawyer for Marriott's family, George Thompson, called Mazzaglia's version of events "hateful fiction" that have no basis in reality.
The body of the University of New Hampshire sophomore has not yet been found despite an exhaustive search along the Piscataqua River in Portsmouth by a variety of law enforcement agencies.
State police affidavits unsealed on Tuesday include claims by Mazzaglia that McDonough tossed evidence into dumpsters and submerged Marriott's body in the Piscataqua River in Portsmouth.
Mazzaglia also claimed that he "and McDonough have formal paramedic training," but neither one of them, "called for medical assistance at any point on the evening of Oct. 9," Hennessey said in the affidavit.
State police were led to McDonough because of a single text message Marriott sent to a friend just hours before she went missing on Oct. 9.
At about 8:55 p.m., Marriott sent a text message to a friend, Brittany Atwood, telling her that she was going to her friend "Kat's" house, according to an affidavit.
"That was the last contact Ms. Atwood had with Ms. Marriott," Hennessey said in the affidavit.
McDonough was questioned twice by police on Oct. 12 while the search for Marriott was under way.
Before leaving for the cemetery, McDonough told police that Mazzaglia came home but left to go jogging. Mazzaglia, during a separate interview on Oct. 12, told police he went jogging on the night Marriott disappeared. He said an injury while running kept him out late, but then he began to provide details about how Marriott died in his apartment, an affidavit said.
