A surfing champion on his way home from a contest and too ill to catch his flight, stopped over at an airport hotel and was subsequently found dead in his hotel room. He was 32 years old.
Unable to board a flight home to Hawaii, it would have been possible to enter the hotel lobby directly from the airport departure lounge and to check in from a check-in kiosk on the meeting room level of the hotel.
The hotel has specially soundproofed rooms, which it would need due to aircraft noise levels. The state of the art air filtration system in designated smoker's rooms are mentioned on the hotel's official website. Painkillers and sleeping pills are reported to have been present at the death scene. The deceased man suffered from a tropical disease carried by mosquitoes, symptoms from which prevented him from being in good enough health to board his flight and had made him withdraw from a surfing contest; reason for his travel presumably.
Presumably no one would have heard him cry out if he had been unable to call emergency or he may have died in his sleep from drug combination overdose. If foul play occurred, no reports have yet speculated, but the situation of the hotel could imply ease of access to guest areas. The deceased man was sponsored by Billabong surf wear and was returning home to his fiance who was expecting his baby in one month.
