AN INSOMNIA sufferer who was convinced he had dementia and a brain tumour stabbed himself twice in the heart, an inquest heard.

On June 15 Stuart Gibb was found by his wife in the garden of their Winnersh house with a knife laying next to his body, after she had tried to call him 26 times on her journey home.

Emergency services were called to the Roundabout Lane property but a 40 minute attempt to resuscitate him proved to be in vain. 

Having taken his son to school that morning the 55 year-old decided to take his life while his wife was at work so that he could not be revived.

Speaking at an inquest at Reading Town Hall on November 14, wife Rosie Gibb said: "I parked my car and called his name. Stu's phone was on the table with lots missed calls.

"I walked into the garden and saw him lying on the floor. I started screaming for help."

Mrs Gibb desperately attempted to resuscitate her partner while emergency services rushed to the scene. 

With paramedics unable to restart the company director's heart however, Mr Gibb was declared dead and flown to Wexham Park hospital.

A postmortem found two stab wounds to the heart and several more to his lower abdomen. 

Although police first treated the case as 'suspicious', when details of Mr Gibb's battle with mental illness and concerns about brain tumours and dementia came to light, the case was reclassified as a suspected suicide.

His mobile phone and iPad's history showed searches such as "what causes loud humming in my head" and "diagnosis and treatment of chronic insomnia".

Mr Gibbs had been taking sleep and depression medication as well seeking help from the Crisis Resolution Home Treatment Team. Leading up to his death he went nine days without any contact from medical professionals.

Assistant Coroner for Berkshire, Emma Jones, said it was beyond any reasonable doubt that Mr Gibb had taken his own life.

"He decided to do it when his family was out of the house so that he could not be revived," she said.

"The gap in treatment was not acceptable but I do not find that more contact would have saved or prolonged his life."
