Cameron Boyce died after an epileptic seizure in his sleep on Saturday, according to multiple reports. The 20-year-old Disney star kept his epilepsy hidden from the public, as he rose to stardom in Grown Ups, Jessie, the Descendants and Mirrors.

Law enforcement officials tell The Blast that because of his age, an autopsy will be performed to find out if he had any drugs or alcohol in his system at the time of his death. The results may take weeks.

In his last interview with Haute Living in May, he opened up about his desire to make a difference: “There’s a long line of difference makers in my family. I’m following in the footsteps of some really strong men and women who have showed me what it means to give back; it’s the greatest way to fulfill yourself.”

Boyce also paid tribute to his African American heritage in the interview. His grandmother, Jo Ann Allen Boyce, was one of the “Clinton 12,” a group of black students who desegregated Clinton High School in Tennessee after 1954’s Supreme Court Ruling, Brown Vs. Board of Education.

He said: “Her story doesn't just inspire me … It hits home with everyone who stops to listen to it. She and the other 11 students set the stage for our generation to come together. We have to ensure — especially with some of the controversy plaguing us now — that we continue to push towards dreams that have yet to be realized. Equality in its truest sense.”

“Being African American and Jewish, I have plenty of ancestors and family members that I can look to for strength, and more importantly, for a grateful outlook on life,” he said. “Every one of them clawed and scratched for my sister and I to be in the position we're in today.”

Boyce walked the walk, volunteering for and contributing to multiple charitable endeavors.

Last April, he won the Pioneering Spirit Award at the 9th Annual Thirst Gala for raising more than $30,000 to build two new wells in Swaziland.
