His son, Jojo Garcia, shared the news on social media, expressing deep sorrow. “With a very heavy heart, I would like to inform everybody that my father, Jeff Garcia, has passed away,” he wrote. “My father was a unique soul. He was unapologetically himself, and I will always admire the love, compassion, and drive that he had. He taught me so much and gave me advice that I live by every single day. He was a Father, Son, Uncle, Cousin, Brother, but most of all, he was my best friend.”

He has made such an impact on people’s lives internationally, whether you grew up watching Jimmy Neutron, or shared a laugh with him at one of his shows,” Garcia’s son added. “He was my hero… I idolized him. He may be gone, but he will NEVER be forgotten. He lives on through our family and friends he loved so dearly, along with the legacy he has created. I know you’re in heaven smiling down and you’re in a better place now. No more pain. I’m going to make you proud pops. Fly high, Rocket Man. LLJG”
