Dr. Kevin Gannon, who helps oversee both Manuel Antonio Urgent Care and Quepos Urgent Care, confirmed to People Magazine that it was the team from Manuel Antonio Urgent Care that responded to the emergency at Arenas Del Mar Beachfront & Rainforest Resort, where the Gardner family was staying.
While Gannon was not the treating physician on-site, he confirmed that his team was the one “performing advanced life support CPR on the site, but there was not much we could do for him.”
Gannon stated that Miller was non-responsive when medical personnel arrived and that CPR was administered for more than 30 minutes.

He added that Miller was “clinically dead when we arrived,” and that “we responded to a patient without vital signs, and he had no vital signs when we arrived.”
Gannon also noted that Miller had not been treated previously at either of the facilities he helps operate, saying, “We do not have records of him at all.”
Although the exact cause of death has not been determined, Gannon confirmed that Miller and his family were experiencing “gastrointestinal symptoms” during the trip.

“We remain committed to supporting our guests and staff, prioritizing their well-being and safety while respecting the privacy of those affected,” the resort’s statement read.
The resort also clarified that “the family did not eat at any of Arenas Del Mar’s restaurants for lunch or dinner the previous day.”

Costa Rican Officials Rule Out Asphyxiation In Miller Gardner’s Death

On March 25, Juan Pablo Alvarado Garcia, an official with Costa Rica’s Judicial Investigation Agency, confirmed that “the preliminary ruling ruled out asphyxiation as the cause of death.”
He further explained that “no macro-level abnormalities were observed in the respiratory tract upon inspection of the body.”
Garcia described the case as a “death under investigation.” Samples have been sent for further testing in histology, toxicology, and neuropathology laboratories.
Brett Gardner’s Son Miller’s Autopsy Delayed Amid Costa Rica’s Surge In Gang Violence

Costa Rica’s Judicial Investigation Agency has confirmed that the full autopsy analysis for Miller will be delayed by at least two to three months, citing a surge in gang-related violence that has overwhelmed the nation’s forensic services.
Miller was found unresponsive in his bed at the Arenas Del Mar Resort in Manuel Antonio last Friday while on a family vacation. According to authorities, multiple members of the Gardner family, including Miller, fell ill the night before after dining at a nearby restaurant. Initial speculation pointed to food poisoning as a possible cause.
Juan Pablo Alvarado Garcia, a spokesperson for Costa Rica’s Judicial Investigation Agency, told the Daily Mail that while an autopsy has already been conducted, the backlog of cases tied to the country’s rising homicide rate is delaying the timeline for results. “We’re having a hike in homicides as these drug gangs battle for territory and every one of them needs an autopsy,” Alvarado Garcia said. “That’s the reality.”
Costa Rica, once seen as one of Central America’s most stable and peaceful tourist destinations, has seen a dramatic increase in gang-related violence in recent years. In 2023 alone, more than 900 homicides were reported, marking a record high for the country.
