Prince William and Prince Harry’s cousin, Rosie Roche, is dead at the age of 20.

Roche, the granddaughter of Princess Diana’s uncle and thus a second cousin to William and Harry, passed away at her family residence on July 14, as reported by the Sun.

A firearm was reportedly found close to her at the property in Norton, England.

The coroner told the outlet police have deemed the death as “non-suspicious” and there was no third-party involvement.

Roche was found by her mom and sister after she had been packing to go on a trip with friends, according to the report.

A spokeswoman told the outlet that Roche, who was studying English Literature at Durham University, “will be sorely missed.”

Reps did not immediately return Page Six’s request for comment.

This isn’t the only tragedy the royal family has suffered recently.

Thomas Kingston, the ex-boyfriend of Kate Middleton’s younger sister, Pippa, died from a self-inflicted gunshot wound in February.

At 45 years of age, she was discovered deceased with a “catastrophic head injury” and a firearm nearby at her parents’ house located in a village in the Cotswolds, England.
