Actress Mia Farrow is mourning the death of her 27-year-old adopted son, Thaddeus Wilk Farrow, who took his own life.
Thaddeus Farrow was found seriously wounded in his vehicle in Roxbury, a town neighbouring his mother's home in Bridgewater in the US state of Connecticut, on Wednesday.

He was later pronounced dead at a hospital.
The medical examiner's office determined the cause of death was suicide during an autopsy. State police had said there was no criminal element to the death.
Mia Farrow tweeted on Thursday that her family is devastated by Thaddeus' death.
"He was a wonderful, courageous person who overcame so much hardship in his short life," she wrote.
"We miss him. Thank you for the outpouring of condolences and words of kindness."
Thaddeus Farrow contracted polio in Kolkata, India, and was paralysed from the waist down. The actress, a child polio survivor herself, adopted him in the mid-1990s.
Mia Farrow has adopted 10 children in her lifetime, and has four biological children.
In 2000, Thaddeus Farrow and his mother participated in a global summit on polio eradication at the United Nations in New York.
