Mia Farrow has spoken out following the death of her son Thaddeus Farrow. The 27-year-old died after suffering a serious injury inside his vehicle on Wednesday (21 September).

The Rosemary's Baby actress took to social media to thank well wishers "for the outpouring of condolences and words of kindness" following the death of her son.

"We're devastated by the loss of Thaddeus, our beloved son and brother. He was wonderful, courageous person who overcame so much hardship in his short life. We miss him. Thank you for the outpouring of condolences and words of kindness," the 71-year-old wrote on Twitter, adding, "If you or someone you love needs help, or if you want to support a group doing life saving work, please visit: https://afsp.org/."

According to reports, Thaddeus was discovered gravely injured in his vehicle on Route #67 in Connecticut. He was transported to Danbury Hospital via ambulance, where he later succumbed to his injury. His death has been ruled as suicide.

Mia adopted Thaddeus from an orphanage in Calcutta, India, in 1994. He had been diagnosed with polio and was a person with paraplegia. He was one of Mia's 10 children she adopted through the years.

In 2013, Thaddeus opened up on what it felt like being adopted by Mia and adjusting to life in America.

"It was scary to be brought to a world of people whose language I did not understand, with different skin colours. The fact that everyone loved me was a new experience, overwhelming at first," he told Vanity Fair.
