(FOX 25 / MyFoxBoston.com) – Police have made an arrest in the death of a UNH student who was reported missing by family and friends on Wednesday.
Seth Mazzaglia, 29, of Mill Street in Dover, was arrested on Saturday in connection with the death of Elizabeth "Lizzi" Marriott. He will be arraigned for second degree murder on Monday.
New Hampshire Attorney General Michael Delaney, along with the FBI and assisting police departments, held a press conference at 1 p.m. on Saturday to announce that the missing 19-year-old was dead and that an arrest had been made.
Authorities said that Marriott and Mazzaglia "knew each other," but would not elaborate.
In a statement, Marriott's family thanked the authorities, the media, volunteers, and the UNH campus community for their involvement in the investigation. They asked for privacy during this difficult time.
"This is the worst parents nightmare, a missing child and with an unfavorable outcome. Please pray for the dedicated rescue professionals who continue to look for Lizzi. We need them to find her and bring her home."
During the press conference, police also said that Marriott's car was found at the UNH campus in Durham.
Mazzaglia graduated from UNH in 2006 with a bachelor's degree in theater.
UNH President Mark W. Huddleston also commented on the tragedy and released a statement saying that the university is "greatly saddened to learn of Lizzi's death." Huddleston extended his sympathies to Marriott's family and friends.
In Lizzi's honor, a moment of silence will be observed at the beginning of the men's hockey game on Saturday night.
The university counseling staff will be available to students who would like to speak with someone.
Marriott, a sophomore in the College of Life Sciences and Agriculture at UNH, was a commuter student residing with family in Chester. She was studying marine biology.
Marriott was last seen on Tuesday. She sent a text to friends around 9 p.m. that night saying she would meet them in Dover, but never showed up. Marriott also failed to show up for work on Wednesday which according to family and friends is out of character.
Marriott's family reported her missing on Thursday when she did not return home.
A candlelight vigil is being held tonight at Bay State Commons in Westborough at 7 p.m. in support of the family and to remember Lizzi.
