Concord Academy

"The Con cord Academy community was devastated to learn that a student critically injured Sunday morning has passed away. She was an independent thinker with a finely tuned sense of humor, and we are all mourning her loss. Right now we are focused on offering support to our students and to the rest of the [Concord Academy] community. Our hearts go out to her family and friends."

Hashem told reporters at an afternoon press conference that he did not know who was hosting the party on William Street or if adults were present. He would not say whether drinking may have been involved. He said police were investigating. "We're trying to find out what she was doing prior to leaving the house, while she was at the house, and what she did after she left the house," said Hashem, adding the house was being treated as a crime scene.

The teen is at least the second in the state to die after leaving a party in recent months. In October, 17-year-old Taylor Meyer of Plainville was found dead in a swampy area, after wandering off from a drinking party in Norfolk. She drowned. A 19-year-old Plainville man was charged with supplying alcohol to her. Hashem said authorities from Andover and Methuen and State Police used dogs and a helicopter to search the area, about 20 miles north of Boston just inside Interstate 495. An officer found the teen submerged in an icy creek that flows into Hussey Brook Pond, a 5-acre pond behind William Street, Hashem said.
