The fact that Mason was not wearing a safety helmet at the time of the incident minimised his chances of survival, investigators told Loop News.
Reports from the Harbour View Police are that about 4:20 am, Mason was driving a CBR motorcycle when he allegedly lost control and fell from the bike. The Police were summoned and Mason was taken to hospital where he was pronounced dead.
"He was flung from the motorcycle and his body was found on the opposite side of the road from where his motorcycle was," a police officer said.
Mason set a Jamaican record of 2.34 metres to win the Pan American Games gold in 2003.
He won silver and bronze medals at the World Junior Championships in 2000 and 2002 respectively, the latter event held in his hometown of Kingston.
Mason, in 2006, switched allegiance to Great Britain based on his father's nationality and went on to win silver in the high jump at the 2008 Beijing Olympic Games.
The former Wolmer’s Boys' High School student, in 2004, cleared 2.25 metres to win bronze at the 2004 IAAF World Indoor Championships.
Prime Minister Andrew Holnes, in response to news of Mason's death, tweeted: "Our sincere condolences to the entire sporting fraternity."
The athlete's grandfather, Eric Mason, expressed sadness over his grandson's death when Loop News visited his home in Harbour View on Thursday morning.
"It's sad very sad. As a matter of fact, I didn't even realise he was here," Mason said.
