The Sheriff's Office and Marathon Fire Rescue were called to the scene around 7:30 a.m. where they pronounced Therriaault dead at the scene.
An autopsy is pending, according to the Sheriff's Office.
A friend to Therriault described the 22-year-old in a tribute as "a beautiful, selfless, free spirited soul."
Private elementary school Butler Montessori also wrote a tribute to Therriault who went there as a child and served as a classroom assistant in her later years.
On Facebook, the school wrote that the 22-year-old "brought joy to everyone who connected with her."
"There are many in our community who have felt the warmth of Sydney's smile and we will be processing our hurt and missing her for a long time," the tribute concluded.
