Several members of the family also fell ill, though details remain unclear as investigators await autopsy and toxicology results.
Hotel staff found Miller unresponsive in his room at the upscale Arenas Del Mar Beachfront & Rainforest resort in Manuel Antonio on March 21. His grieving parents, Brett and Jessica Gardner, confirmed the heartbreaking news, stating, “We have so many questions and so few answers at this point, but we do know that he passed away peacefully in his sleep.”
