The family statement did not include a cause of death, but worldwide media outlets have reported it as a possible drug overdose. "The matter remains under investigation by the Barnstable police as well as state police detectives assigned to the Cape and Islands district attorney's office".
Hyannis Fire Capt. Greg Dardia told Fox News Police that paramedics responded to a medical call at 28 Marchant Avenue at around 2.30 pm.

Saoirse had been studying communications in Boston College, where she was said to be an engaging student who was concerned about numerous issues plaguing contemporary society. Kerry Kennedy, Saoirse's aunt, took to Instagram to honor her deceased niece, whom she said was "passionately moved by the causes of human rights and women's empowerment and found great joy in volunteer work".
Saoirse got candid about her battle with depression three years ago when she was still a high school student.
In an op-ed for her high school publication almost a decade later, Saoirse described a struggle with mental illness. "She is loved and will be deeply missed".
'I did the worst thing a victim can do, and I pretended it hadn't happened.
Hill went on to attend Boston College.
She hoped that by speaking out about her struggles it would help other students suffering from mental illness.
Hill was born to Courtney Kennedy - the fifth of Robert and Ethel's eleven children - and Paul Hill, one of four Irish people wrongly imprisoned for fatal pub bombings in 1974. His conviction was eventually overturned but he had spent 15 years in prison by then.
The family lived in Ireland from 2002 until 2006, when they legally separated.
Ms Hill's death comes weeks after the 50th anniversary of the scandal surrounding a fatal vehicle accident in which RFK's younger brother, then-senator Edward Kennedy, drove off a bridge connecting the tiny island of Chappaquiddick to Martha's Vineyard, killing his passenger, Mary Jo Kopechne. RFK, a senator and presidential candidate, was assassinated in 1968.
"Saoirse will always remain in our hearts", former Congressman Patrick J. Kennedy wrote.
JFK's son, John F. Kennedy Jr., was killed with his wife and sister-in-law when his small plane crashed off Martha's Vineyard, Massachusetts, in July 1999.
