Authorities suspect that the elderly parents of actress Alicia Witt may have died of hypothermia given one of the victims was found wearing a coat.
Robert Witt, 87, and Diane Witt, 75, were discovered unresponsive on Monday, after their 46-year-old daughter asked a relative to perform a welfare check on them because she was unable to reach them.
Neighbours told Boston 25 that the Cybil star's parents were older and dealing with medical issues.
"He had cancer she was recently diagnosed with Parkinson's disease. She was a frail little thing, a good wind would blow her away," a neighbour said.
In a statement, Witt, 46, said: "I reached out to a cousin who lives close to my parents to check on them. Sadly, the outcome was unimaginable.
"I ask for some privacy at this time to grieve and to wrap my head around this turn of events, and this surreal loss."
An autopsy will be conducted to determine an official cause of death.
