The grandson of oil tycoon J. Paul Getty has died.
John Gilbert Getty, one of the heirs to the $5 billion (£3.7bn) fortune, was found unresponsive at a hotel in San Antonio, Texas on Friday.
The cause of the 52-year-old's death has not yet been made public.
"With a heavy heart, Gordon Getty announces the death of his son, John Gilbert Getty," a spokesperson for his composer dad said in a statement.
"John leaves behind his daughter, Ivy Getty, whom he loved beyond measure, and his brothers Peter and Billy.
"His brother, Andrew, predeceased John. John’s mother, Ann Gilbert Getty, passed this September.
"John was a talented musician who loved rock and roll.
"He will be deeply missed."
The family, who once held the largest private fortune in America thanks to their oil money, have been shrouded by mystery and tragedy in recent years.
Six years ago John's brother Andrew was found dead at his LA home in 2014 after intestinal bleeding, according to People.
John's sister-in-law lost her life following a heroin overdose.
His daughter Ivy shared a tribute to her father online.
“My father was awesome- coolest man to ever land on this planet and I will forever be the proudest daughter," she wrote.
“Love you so much Dad....life is cruel sometimes.... I have not one, but two guardian angels watching over me now...here are some of my favorite pictures of him (and selfishly a couple of us).”
Gigi Gaston, whose mother was the fifth wife of the late oil tycoon, also mourned John’s death.
“I just heard my dear John Getty passed!" she wrote on Facebook..
"I love you John! No birthday will ever be the same - my life won’t!
"I love you. Rest in Peace.”
John’s father, Gordon, helped facilitate the sale of his father’s business, Getty Oil, following the billionaire’s death in 1973.
