“We are shocked, saddened and heartbroken,” they wrote. “Our father was an incredible man who cared about everyone and their well-being.”

They continued: “He will be missed tremendously. It will forever be ‘Tito Time’ for us. Please remember to do what our father always preached and that is ‘Love One Another’. We love you Pops.”
