On Thursday, a misadventure verdict was recorded by State Coroner Victor Yeo on the 10-year-old's death last September.

Investigation officer Joe Kok Jianwei told the court that at about noon on Sept 7 last year, Jonathan's father Mr Kenneth Chow Heng Kit had taken him and his two younger children - aged nine and eight - to the Palm Gardens condominium pool for a dip.

Jonathan enjoyed swimming and had taken lessons for three months last year at Grace Orchard Special School where he was a student.

While his children were frolicking in the one-metre-deep section of the pool, Mr Chow, 39, a company director, read the newspapers at the poolside.

Half an hour later, his reading was rudely interrupted by shouts of 'Jonathan had a fits' from his second child. Jonathan was facing down and shaking violently on the surface of the pool. Mr Chow jumped in and pulled the boy out.

By then, the boy had stopped convulsing and appeared to be staring blankly at his dad.

A desperate Mr Chow tried pumping water out from Jonathan's stomach and asked a passer-by to call for an ambulance.

The father then switched to giving his son cardio-pulmonary resuscitation when he realised that the 10-year-old was not breathing.

But it was too late. Singapore Civil Defence Force paramedics found Jonathan without a pulse when they reached the condominium.

At 2.45pm, the boy was pronounced dead at the National University Hospital (NUH).

Investigations also found that Jonathan had been seeking treatment at the same hospital for epilepsy and was on medication since he was a toddler.
