As for how the agency initially came to the preliminary findings before then backpedaling?

“When our agents showed up at the scene, they observed the body with vomit in the mouth and nasal passages,” Alvarado Garcia explained to the Daily Mail in an interview published March 26. "So they provided a preliminary report saying it could have been asphyxiation due to the vomit. We went with that version because the night before the family went to dine outside the hotel where they were staying, and they all started to feel sick when they returned. But once there was a deeper examination with the autopsy, the doctor did not find any abnormalities in the respiratory tract."

Still, it might take some time before the Gardners learn how Miller died.

"We're having a hike in homicides as these drug gangs battle for territory and every one of them needs an autopsy," Alvarado Garcia noted to the outlet. "I can confirm that an autopsy has been carried out on Miller. But the full analysis and results, as in every one of them, will take at least two to three months due to these constant killings causing a backlog of cases. That's the reality."

For now, the Gardners and the sports community are continuing to honor Miller’s legacy—with the New York Yankees paying tribute on Opening Day March 27. 

As his parents wrote in their March 23 statement, “Miller was a beloved son and brother and we cannot yet comprehend our life without his infectious smile. He loved football, baseball, golf, hunting, fishing, his family and his friends. He lived life to the fullest every single day.”
