She attended class the Tuesday she disappeared and made plans to visit friends in Dover. Her cellphone was used that night, according to fliers family members posted around town.

Friends and family have described Marriott as a fun-loving, trusting young woman with a wide circle of friends who was active in chorus and a prom queen in high school. She loved animals, volunteered at the New England Aquarium and was helping put herself through school by working at Target.

Mazzaglia graduated from the University of New Hampshire in 2006 with a degree in theater. Friends have said they were shocked to hear of his arrest.
