Cause of teacher’s death a mystery

DOCTORS are baffled by the sudden death of a teacher who rolled out of bed and stopped breathing.

Luisa Paola Colman’s husband tried to revive her before paramedics arrived at their Balby home but there were no signs of life.

A post-mortem examination and other tests on the 53-year-old nursery teacher have failed to establish why she died.

Pathologist Suzanne Rogers told a Doncaster inquest it was one of the rare cases each year which she has to record as ‘unascertained’.

Mrs Colman was on medication for ailments including an underactive thyroid and high blood pressure before her death on Bonfire Night last year.

She had gone to bed early because of tiredness and when her husband, Gary, also a teacher, went up she was asleep.

Around 12.30am he became concerned because her breathing sounded unusual.

He gave her a tap and she rolled off the bed and onto the floor.

Police officers called to the house in Grenville Road said there were no signs of any suspicious circumstances.

The autopsy carried out by Dr Rogers showed no evidence of heart disease or arterial bloodclots. Sleep apnoea was “not a likely explanation”, Dr Rogers said.

She said Mrs Colman’s thyroid problem and hypertension would not normally lead to death.

“The most likely explanation is there was some disturbance of the rhythm of the heart but it is not something I am able to see under a microscope or in tests,” she said.

Recording a verdict of natural causes, Deputy Coroner Fred Curtis said: “This was a very sudden and totally unexpected death and must have come as a dreadful shock.”
