This is the first picture of Prince William and Prince Harry‘s cousin Rosie Roche, who has tragically been found dead at the age of just 20.

The Durham University student was discovered by her mother Pippa and sister Agatha at her family home in rural Wiltshire.

A firearm was found near to her body at the property in Norton. She had been packing for a trip away with friends, an inquest heard.

A

spokesman for the family said the 20-year-old ‘will be sorely missed’.

Emergency crews were pictured responding to a serious incident at the family home at around 1pm on Monday, July 14. An ambulance, three ambulance officers, two firearms officers and numerous local response officers were in attendance.

Rosie was the granddaughter of Princess Diana‘s uncle, the 5th Baron Fermoy, Edmund Roche, who killed himself in 1984 after suffering from a long bout of depression.

He was found dead aged just 45, from a gunshot at his home, Eddington House. His sister Frances was the mother of Princess Diana.

Last February, Thomas Kingston, the husband of royal Lady Gabriella Windsor, died with a gun found near his body at his parents’ home in the Cotswolds.

Coroner Grant Davies said police ‘have deemed the death as non-suspicious and there was no third-party involvement’.

A spokesman for Wiltshire Police said on July 14: ‘This relates to the sudden death of a woman in her 20s.

‘There are no suspicious circumstances and our thoughts are with her family.
