Mia Farrow has been a mother to 14 children in her life, but the death of adopted son Thaddeus at age 27 isn't the first time the actress is facing the loss of one of her own.
Farrow has 11 living children, four biological and seven adopted. Thaddeus is the third adopted child she has lost.
Thaddeus was found inside his vehicle on Wednesday in Connecticut "suffering from a life threatening injury," according to a police report. He was pronounced dead at a local hospital.
There is no criminal aspect to the case, although it is under investigation.
According to reports, Thaddeus lived in Torrington, about 24 miles from where he was found. Public records show he lived at his mother's property until a few years ago.
Thaddeus, who contracted polio in an orphanage in India and was paralyzed from the waist down, was adopted by the actress in 1994, years after Farrow separated from partner Woody Allen.
At the time of a Vanity Fair article in 2013, Thaddeus was studying to become a police officer and offered insight into what it was like to be adopted by a Hollywood star.
"It was scary to be brought to a world of people whose language I did not understand, with different skin colors," he said. "The fact that everyone loved me was a new experience, overwhelming at first."

Matthew and Sascha Previn
Farrow and second husband André Previn welcomed biological twin boys in 1970. Matthew, who graduated from Yale and Georgetown Law, now works as a lawyer in New York City. He married fellow lawyer Tarnisha Antoinette Graves in 2003. The couple have two children, according to Vanity Fair.
Sascha, a graduate of Fordham University, is a stay-at-home dad who cares for his daughter with his second wife, a pediatric cardiologist, Vanity Fair reported. His previous marriage ended in 1995. At that time, he worked as an accountant at a media buying company in New York.
In 1973, Farrow and Previn brought their first adopted child into the family, a baby girl from Vietnam named Lark.
In 1991, Lark made headlines when she and her younger sister Daisy were arrested for shoplifting hundreds of dollars' worth of lingerie from a store in Danbury, Connecticut, while attending a prestigious all-girls high school in Manhattan.
She died on Christmas Day in 2008 at age 35. The cause of death was not released, but she had previously received hospital treatment for AIDS-related pneumonia. Lark had two daughters, Sara and Christine.
Farrow and Previn welcomed their third biological son in 1974. He graduated from Connecticut College in 2000 and works as an executive assistant at IBM while his wife is a graphic designer, Vanity Fair reported. Fletcher has two daughters. He was described as his mother's "protector," even living next door to Farrow in Connecticut.
Summer "Daisy" Previn
Born in 1974, Daisy was adopted from Vietnam in 1976 by Farrow and Previn. Like her older sister, she had a troubled adolescence, including the shoplifting arrest. Daisy dropped out of Wheaton College after one semester and married Lark's husband's brother after becoming pregnant. She is is now a construction manager in Brooklyn, married to a musician, with a son from her first marriage.
The sixth child added to the Previn family was born in 1970 but adopted in 1978 from Korea, just one year before the couple divorced.
Soon-Yi and Allen, who is 35 years her senior, began a relationship in the late '80s when the director was in a long-term relationship with Farrow. Infuriated by the affair, Farrow and Previn cut her off from the family. In her memoir What Falls Away, Farrow depicts the girl as a naive child who was corrupted by Allen.
Soon-Yi has been married to the director since 1997 and they have two adopted daughters.
After separating from Previn, Farrow adopted a 2-year-old boy with cerebral palsy from Korea in 1980. Moses was later adopted by Woody Allen in 1991.
He attended Dalton, an elite Manhattan prep school, before studying at Siena College and the University of Connecticut. He currently lives in Connecticut, where he has a family and works as a licensed family therapist.
Moses came to Allen and Soon-Yi's defense in 2014, estranging him from many of his siblings and Farrow.
"My mother drummed it into me to hate my father for tearing apart the family and sexually molesting my sister," Moses told PEOPLE. "And I hated him for her for years. I see now that this was a vengeful way to pay him back for falling in love with Soon-Yi."
Farrow adopted a baby girl from Texas in 1985, and Allen formally adopted Dylan in 1991.
In 2014, Dylan accused Allen of sexually abusing her as a child. She faced backlash, including from her brother Dylan, who suggested their mother planted the idea.
Dylan, who now works as a writer, welcomed her first child, daughter Evangeline, with her husband in September.
After five years of failed attempts to conceive, Farrow and Allen welcomed son Satchel, who later changed his name to Ronan, in 1987.
Ronan graduated from Bard College at only 15 years old, making him the youngest graduate in the school's history. He went on to earn a degree from Yale Law School in 2009 and also served as a UNICEF ambassador for most of the 2000s.
By the time he was 25, he was an adviser to Secretary of State Hillary Clinton and named as a Rhodes Scholar.
In 2013, it was suggested that Ronan's father was actually singer Frank Sinatra and not Allen. The allegation was never confirmed.
From February 2014 through February 2015, he hosted Ronan Farrow Daily on MSNBC. He continues to work as an investigative reporter.
Farrow adopted a blind girl from Vietnam named Tam one month after learning about the affair between Allen and Soon-Yi.
Tam had a heart condition and passed away in March 2000 at age 19 of heart failure.
Isaiah was adopted the same week as Tam in 1992. In 2012, he accompanied his mother to Time's 100 Most Influential People party.
He attended the University of Connecticut, according to his LinkedIn profile.
Quincy was adopted in 1994 when she was a year old after being born to "a drug-addicted inner-city mother," according to Ronan in the Vanity Fair article. She was originally called Kaeli-Shea but changed her name. She currently attends college in Connecticut.
Farrow adopted Frankie-Minh, a blind girl from Vietnam, in 1995.
