Officials said in April that the death of Brett Gardner's 14-year-old son, Miller, was caused by carbon monoxide, but authorities are reportedly still investigating whether it was a homicide.

The Gardner family announced Miller's death on March 23, two days after he had died. Officials ruled the cause of death on April 3 after they investigated both food poisoning and asphyxiation.

However, according to ESPN, a spokesperson for the Costa Rican prosecutor's office handling the case said the case remains under investigation, and prosecutors are still determining if the death will be ruled a homicide.

"The purpose of the investigation is precisely to determine whether or not we are dealing with a possible homicide. For this reason, it is not possible at this time to confirm or rule out that a crime has been committed," the spokesperson said.

Miller was tested for carboxyhemoglobin, a compound generated when carbon monoxide binds to hemoglobin in the blood. The test showed a saturation level of 64%. It is considered lethal when carboxyhemoglobin saturation exceeds 50%. 

The Gardner family stayed at the Arenas Del Mar hotel in Manuel Antonio.

Several members of the family fell ill during the trip, the Gardners announced.
