Stephen Gately mystery - making some sense at last

From the acres of speculation about the cause of Stephen Gately's death, here's one golden nugget from his mother, via her lawyer and the Mirror. It appears to make sense of the tragedy:

Stephen Gately's shattered mum believes he died from a previously undetected heart condition that has plagued his family.
Margaret Gately told the family's lawyer Gerald Kean: "As soon as I heard he had died I knew it was a heart problem. It has lifted a huge burden off our family's shoulders."
A postmortem yesterday revealed Stephen died from natural causes due to acute pulmonary oedema, a build-up of fluid on his lungs. Most cases are related to heart failure or the early stages of heart disease.
Stephen's father Martin has seen several relatives die prematurely from heart trouble.
The rest of the Gately family will have medical checks to see if they are at risk.
Mr Kean said: "Margaret felt all along Stephen died from a heart-related problem.
"There is a heart condition on his dad Martin's side of the family. Stephen would have had no idea he had this condition."
