In a statement obtained by PEOPLE, Olivia’s grandfather said the family she leaves behind is beyond devastated.
“Olivia was a smart, vibrant, beautiful young woman with a bright future ahead of her,” reads the statement from Paul Bergstrom. “She was a beloved daughter, sister, granddaughter, niece, and friend. Olivia was a lover of animals who never met a horse she couldn’t win over. She was passionate about living a healthy life. She had a dog named Scarlett. She loved her family fiercely.
“Our hearts are broken at the thought of Olivia not being in our lives, taken from us and her future in a way we cannot comprehend,” the statement continues. “We know her spirit remains with us and we will do everything in our power to keep her memory alive and celebrate the short time we had the privilege of having her in our lives. We ask for our privacy and your respect at this time as our family begins the long journey of rebuilding our lives.”
