The baseball star and his wife, Jessica. made the tragic announcement Sunday that their 14-year-old son had died from a sudden illness after the entire family got sick while on vacation in the Central American country.

They said: "Miller was a beloved son and brother and we cannot yet comprehend our life without his infectious smile."

But his sudden death has been met with shifting explanations as it now appears the teen may have never stood a chance after being given potentially bad medication to treat his illness.

The country's Judicial Investigation Police (OIJ) initially attributed Miller's death to "asphyxiation due to intoxication related to food poisoning."

But investigators then revealed asphyxia had been ruled out, as there was no obstruction of the teen's airway.

Now authorities are probing whether Miller was allergic to any medicine he was given.

The shocking reversal comes after the entire family fell ill after returning to their resort from dinner on Thursday night.

While the family meal did not occur at the Arenas Del Mar resort where they were staying, the hotel said a licensed doctor was dispatched to "handle the emergency situation."

"Our hotel protocol at Arenas Del Mar does not allow for hotel staff to provide any medication to guests," the resort added.

The family is still searching for answers as it is believed that an autopsy could take two or three months to be completed.

Police from the nearby town of Quepos are now leading the investigation, and have began questioning resort employees.

Miller and his family were staying at the $900 per night beachfront resort when he was found dead on Friday morning.
