The 22-year-old granddaughter of Robert F. Kennedy died Thursday at the Kennedy compound in Hyannisport, Mass., the family said in a statement.

The woman, identified by the family as Saoirse Kennedy Hill, was the daughter of Courtney Kennedy Hill, the fifth of 11 children born to the late New York senator and wife Ethel, The New York Times reported.

"Our hearts are shattered by the loss of our beloved Saoirse," the family said. "Her life was filled with hope, promise and love. She cared deeply about friends and family, especially her mother Courtney, her father Paul, her stepmother Stephanie, and her grandmother Ethel."

Hyannis Fire Capt. Greg Dardia told Fox News Police that paramedics responded to a medical call at 28 Marchant Avenue at around 2:30 p.m. Hill was taken to Cape Cod Hospital in an unknown condition. It is not clear whether she died at the hospital or at the property.

Boston 25 News, citing a law enforcement source, reported that Hill died from a suspected drug overdose.

"Earlier this afternoon Barnstable Police responded to a residence on Marchant Ave in Hyannisport for a reported unattended death," Cape and Islands Assistant District Attorney Tara Miltimore said in a statement. "The matter remains under investigation by Barnstable Police and State Police detectives assigned to the District Attorney's Office."

In a 2016 opinion piece for Deerfield Scroll, the student newspaper for the Deerfield Academy boarding school, Hill wrote about her bouts with depression.

"My depression took root in the beginning of my middle school years and will be with me for the rest of my life," she wrote. "Although I was mostly a happy child, I suffered bouts of deep sadness that felt like a heavy boulder on my chest. These bouts would come and go, but they did not outwardly affect me until I was a new sophomore at Deerfield." Read more at FOX News
