A cause of death for Santaella, 44, was not made public.
A GoFundMe campaign launched for Santaella's loved ones, including his daughter, Adrianna, had raised more than $3,200 as of press time.
"Everyone that knew Rob loved him for his kind soul and larger than life personality," reads the campaign, launched by Rosie Vega. "No matter the battles Rob suffered with his health, he always fought to continue to live. Unfortunately, God has called him home."
