Los Angeles: Actress Mia Farrow's India-born son Thaddeus Wilk Farrow died from a "suicide gunshot wound" to the torso, the Connecticut medical examiner's office said.
The state medical examiner's office determined the cause of death Thursday after an autopsy. No further details were revealed, reported USA Today.
Thaddeus, 27, was found gravely injured in his car on Wednesday in Roxbury "suffering from life-threatening injuries," according to the state police report.
He was taken to Danbury Hospital, where he was pronounced dead. There was "no criminal aspect" to the death.
The "Rosemary's Baby" star broke her silence about Thaddeus' death with a post on Twitter in which she asked fans to lend their support to the American Foundation for Suicide Prevention.
"We're devastated by the loss of Thaddeus, our beloved son and brother. He was a wonderful, courageous person who overcame so much hardship in his short life. We miss him," Farrow posted.

Thaddeus, a paraplegic due to polio, was adopted by Farrow in 1994 from an orphanage in Calcutta, India, following her divorce from Woody Allen.
Farrow has nine other adopted children. She also has four biological children, including Ronan Farrow whom she had with Allen as well as Fletcher Previn and twins Matthew and Sascha Previn with her second husband Andre Previn.
