A Massachusetts family of four were found dead

WAKEFIELD, N.H. (AP) — A Massachusetts family of four were found dead on Christmas Day at their lake house in New Hampshire after their propane heating system appeared to have malfunctioned, poisoning them with carbon monoxide gas overnight, authorities said Friday. Matthew Goldstein, 52, was an elementary school teacher in Chestnut Hill and his wife Lyla Goldstein, 54, was a project manager at Microsoft. Their daughters, Valerie, 22, who was also a teacher, and Violet, 19, a college student, also died in the accident. The family lived in Newton, Massachusetts, and were visiting New Hampshire over the Christmas holidays. Investigators said they haven’t yet figured out what caused the apparent leak of carbon monoxide from the propane gas heating system.
