Cameron Boyce, Disney Channel Star, Dead at 20

The rising star reportedly died in his sleep on Saturday.

Disney Channel star Cameron Boyce has died.

The 20-year-old TV star, who appeared in a number of Disney Channel shows including Descendants, Shake It Up and Liv and Maddie, died of a seizure in his sleep on Saturday night, a spokesperson for his family confirmed to ET. 

A spokeswoman for the Los Angeles County Medical Examiner-Coroner tells ET that Boyce was found unresponsive in a home in the 5100 block of Cartwright Avenue in North Hollywood on Saturday. According to the spokeswoman, authorities were called and Boyce was pronounced dead at the scene. Boyce had an ongoing medical condition and according to TMZ, when EMTs arrived at his home, they could not revive him. 

The spokeswoman also tells ET that an autopsy was performed on Monday and a cause of death was deferred pending further investigation.

"It is with a profoundly heavy heart that we report that this morning we lost Cameron," the Boyce family spokesperson told ET. "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."

Early on Sunday morning, a number of posts began appear to commemorate Boyce’s life – including from Bob Iger, Chairman and CEO of The Walt Disney Company.

"The Walt Disney Company mourns the loss of #CameronBoyce, who was a friend to so many of us, and filled with so much talent, heart and life, and far too young to die," Iger wrote. "Our prayers go out to his family and his friends."

Adam Sandler, who played Boyce’s father in Grown Ups and Grown Ups 2, wrote: “Too young. Too sweet. Too funny. Just the nicest, more talented, and most decent kid around. Loved that kid. Cared so much about his family. Cared so much about the world. Thank you, Cameron, for all you gave us. So much more was on the way. All our hearts are broken. Thinking of your amazing family and sending our deepest condolences.”

Aside from acting, Boyce was also dedicated to giving back. Last year, he received The Pioneering Spirit Award at the 9th Annual Thirst Gala for helping raise over $30,000 to build two wells in Swaziland, bringing clean drinking water to communities in the region. He was also a staunch advocate for America's homeless.
