On Friday morning, a post on her fundraising page read, "Sweet Kate went to be with the Lord at 8:23am. She is now dancing with Jesus! Rest in Peace Katelyn!"
The night before, friend Kristi Buckner shared an update via Katelyn's mother, writing, "The Drs. have sedated Kate. We pray she goes peacefully in her sleep."
During her all-too brief lifetime, Katelyn had earned the love and respect of her hometown, Campbell County, Tenn., which, after her diagnosis with aggressive bone cancer called osteosarcoma, not only worked to make her bucket list come true, but proudly wore green as a sign of community support for her.
Topping Kate's list was a trip to Italy, which sadly did not come to pass. But two other major wishes were granted – to attend her school prom and to ride a motorcycle.
The prom at school was held in her honor this week, with a special gathering simultaneously taking place in her room at Tennessee Children's Hospital. And her motorcycle ride took place some days before, as she rode in the car and the bikers circled around her.
Also on Katelyn's list was to see the band Of Mice & Men in concert and pick up an autographed T-shirt from them. The group's fans responded by flooding the band's Facebook page and Twitter accounts and linking to Katelyn's story, reports ABC News.
Tweeted the band's lead vocalist Austin Carlile earlier this week: "I told her not to be afraid because she wouldn't be alone. My mom is already an angel and would be taking care of her."
In Friday's message, Carlile said, "Heaven gained another angel this morning. #RIPKatelynNorman Her light will never go out. She'll always be in my heart. I promised her that."
