Viral internet star Lil Tay has died, her family announced Wednesday, at the age of 14.

“It is with a heavy heart that we share the devastating news of our beloved Claire’s sudden and tragic passing,” her family said in a statement. “We have no words to express the unbearable loss and indescribably pain. This outcome was entirely unexpected, and has left us all in shock.”

Little has been revealed about the death of Tay, whose real name is Claire Hope. Her family’s statement also announced the death of her brother, also with sparse detail, adding that both deaths are “under investigation.”

“Her brother’s passing adds an even more unimaginable depth to our grief,” the statement said, adding a request for privacy “as the circumstances surrounding Claire and her brother’s passing are still under investigation.”

The rapper and influencer rose to fame in 2018 when she was just 9, posting rap videos and clips of her “flexing” money and expensive possessions on social media.

She racked up more than 3 million followers during that time, but has been largely inactive on social media since then. Her last Instagram post was in June 2018 to mourn the loss of “father figure” XXXTentacion.

In 2018, Claire’s family was accused of abusing the internet star. Her mom and brother faced allegations of forcing Claire to make content, coaching her on how to stir controversy and garner the most attention.

Meanwhile, Claire’s father was accused of physically and mentally abusing her—as well as taking a chunk of her earnings—alongside his wife, according to a GoFundMe campaign started by Claire’s brother. Claire was court ordered to live with her father in Canada in 2018, and has been largely silent on social media ever since.
