Sarah Ferguson said she is “shocked and saddened” after her former assistant was murdered in the US.
Jenean Chapman, 46, was found dead by police at her apartment in Dallas, Texas, on Monday.
She was the Duchess of York’s personal assistant for four years between 2001 and 2005.
Fergie wrote on Instagram: “I am shocked and saddened to learn that Jenean Chapman, who worked with me as my personal assistant many years ago, has been murdered in Dallas aged just 46. A suspect is in custody.
“Jenean was loyal, hardworking, beautiful and fun and my heart breaks for her family and friends. I heard from her just a couple of months ago and she seemed so happy. Her family is raising money to transport her body back to New York City and pay for legal and funeral costs.
“I will be making a donation and supporting the family in any way possible - please help if you can at the link in my bio.”
She pledged to help the family with funeral costs.
Jenean began working with Fergie as her first job after graduating from university in New York.
Her family said she started a job in Dallas five months ago.
James Patrick, 48, has been arrested on suspicion of her murder. He remains in custody.
