Mia Farrow's son, Thaddeus Wilk Farrow, died Wednesday at Danbury Hospital in Connecticut, where the 71-year-old actress lives. He was 27.
Law enforcement officials say Thaddeus was found in his car suffering from a life threatening injury, and was transported to the hospital, where he was pronounced dead. There is no foul play suspected, according to the report from Connecticut state police obtained by ET. No additional details have been released at this time.
Thaddeus -- who was paraplegic as a result of suffering from polio -- was adopted by the Rosemary's Baby star from Calcutta, India 22 years ago. He is one of 10 children Mia has adopted.
