Costa Rican Officials Raid Hotel Where Ex-Yankee Brett Gardner Son Died

Officials have conducted a raid at the Costa Rican hotel where former New York Yankees outfielder Brett Gardner‘s son, Miller, died … as investigators look into whether the matter is a manslaughter case.

According to ESPN — which spoke to prosecutor Kenneth Alvarez — a three-hour search of the Arenas Del Mar Beachfront & Rainforest Resort in Manuel Antonio took place on Thursday to collect more evidence — both physical and digital.

14-year-old Miller died on March 21 after falling ill while vacationing with his family … and an autopsy determined carbon monoxide was the cause.

Alvarez said at the time, toxic substance measurement tests were taken … and Thursday’s raid was a follow-up on those results.

The search targeted the management, maintenance and accounting offices at the resort … and officials say they have also spoken with employees, who have been cooperative.

Initially, it was reported he died from asphyxiation and food poisoning — before officials later determined a machine room next to the family room likely led to his passing.
