New information has emerged regarding the death of Kelly Lee Curtis.

Two days after Jamie Lee Curtis announced that her sister Kelly had died at the age of 69, the Blaine County coroner’s office of Idaho confirmed to Us Weekly that she died of natural causes. Officials also shared details about her final days, saying she had been in hospice care in the week before her death on May 30.

The coroner’s office added that Kelly is expected to be cremated and that her husband John Marsh had been present when the coroner arrived.

In the wake of her passing, Kelly was remembered fondly by her sister, with Jamie writing on Instagram, “A warm aloha to my older sister, Kelly Lee Curtis. She passed away this morning. In her home. In nature. At peace.”

“She was my first friend and lifelong confidant,” the Oscar winner added. “She was jaw droppingly beautiful, and a talented actress. She played a mean game of hearts, collected turtles, loved her family, nature, music, thrifting, travel, Facebook, and Pokémon Go. She was proud of her Danish roots and Hungarian Jewish ancestry and was a devoted American patriot.”
