The cause of death has been revealed for Prince William and Harry’s 20-year-old cousin Rosie Roche, roughly a week after she was found dead with a firearm nearby.

Roche’s death has been ruled the result of a “traumatic head injury,” according to The Independent, who cite the Wiltshire and Swindon coroner.

A coroner previously told the UK Sun that while an investigation had been opened, Roche’s death was not considered suspicious and there were no other people involved.

Roche — the granddaughter of Princess Diana’s uncle Edmund Roche — was found dead on July 14 at her family’s home in Norton, Wiltshire, according to The Times. She was reportedly discovered by her mother and sister after she said she was packing to go on a trip with friends.

At the time of her death, Roche was a student at Durham University, where she was studying literature.

“Roche, Rosie Jeanne Burke, died on Monday 14th July 2025,” read an obituary published by the Yorkshire Post on Saturday. “Darling daughter of Hugh and Pippa, incredible sister to Archie and Agatha, Granddaughter to Derek and Rae Long.”

The obituary noted that a private funeral would be held for the family, as well as a memorial service at a later date.

Neither Prince William nor Prince Harry has spoken publicly about Roche’s death.
