Cameron Boyce's grandmother and activist Jo Ann Allen Boyce has died at age 84 after a battle with pancreatic cancer. Jo Ann was surrounded by her family at her home in California when she died on December 3, the Los Angeles Times reported on Saturday, December 6. The activist attended the first integrated public high school in the South after the U.S. Supreme Court's 1954 ruling in Brown v. The Board of Education. Sculptures of Jo Ann and 11 of her fellow students are erected in the Green McAdoo Cultural Center in Clinton, Tennessee. "It is with a very heavy heart that we share the news that our friend Jo Ann Allen Boyce passed away yesterday," the center wrote via Facebook on December 4. "We've lost such a caring and humble soul. Jo Ann was someone who was so generous with her own story and shared it with people across the country. I spent some time with her a few years back in Wisconsin, where she told her story to student bodies and every day citizens."

A student was so inspired by her story that they wept when they met her, and Jo Ann was quick to offer them a warm hug. Jo Ann inspired everyone she met. Today is a tough one for all of us she did. We send our love and care to the Boyce family." Jo Ann's death comes six years after Cameron died at age 20 after suffering an epileptic seizure. (Boyce had previously been diagnosed with epilepsy, and his cause of death was determined to be a sudden unexpected death in epilepsy.) "It is with a profoundly heavy heart that we report that this morning we lost Cameron," a spokesperson told Us Weekly at the time, on behalf of the family. "He passed away in his sleep due to a seizure which was a result of an ongoing medical condition for which he was being treated. The world is now undoubtedly without one of its brightest lights, but his spirit will live on through the kindness and compassion of all who knew and loved him." The statement continued: "We are utterly heartbroken and ask for privacy during this immensely difficult time as we grieve the loss of our precious son and brother." Cameron Boyce's Mom Reacts to Adam Sandler's Tribute in 'Happy Gilmore 2' Jo Ann, for her part, paid tribute to the Disney Channel star days after his death. "His nature, his giving nature, loving nature. That's his legacy. As well as his talent," she said while speaking with ABC's Tennessee affiliate WATE. "And for him to be a part of that and to share that with his young viewers. To show that his grandmother had been involved in something that he felt like he was stepping on my shoulders and to make the world a better place, that was an incredible experience." She continued, "He is a star. But he's like a different kind of star. He's a shining star in the sky. We're grateful for everyone who is sending us the love and the support that we need right now. Thank you."
