Prince William and Prince Harry have lost a cousin, Rosie Roche, who died from a traumatic head injury at the age of 20. Her body was discovered in her home in England by her family members. The coroner has stated that there is no evidence to suggest foul play or third-party involvement.
Roche was a student at Durham University, where she studied English Literature. She was described as an “incredible sister” by her siblings and will be laid to rest in a private funeral and memorial service. Despite initial reports suggesting the cause of death may have been related to police investigation, the coroner has since confirmed that it was due to the head injury.
The royal family’s cousin had no known connection to Princess Diana beyond being the grandchild of one of her relatives. A gun was found at the scene, but its role in Roche’s death remains unclear. The investigation has concluded that Roche took her own life. Support is available for those struggling with mental health issues; help can be accessed by calling 988 or visiting 988lifeline.org.
