A 31-year-old plasterer died after taking a cocktail of drugs, an inquest heard.

Damian Burgoyne, 31, had taken the anti-psychotic medication olanzapine, methadone, cocaine, amphetamines and ecstasy before he was discovered by his partner Michelle Astbury at their Piccadilly Road home in Burnley, the town's coroner's court heard.

Dr Zuhir Twage, a consultant pathologist at Burnley General Hospital, said that the levels of the drugs in his system alone would not have proved fatal to Mr Burgoyne, who was described as a promising former junior golfer.

But the drugs, combined with alcohol also found in his system at a post-mortem examination, were toxic enough to led to his death, according to the doctor.

The inquest heard that former Towneley High pupil Mr Burgoyne had been out with friends before his death on May 22 last year.

But Miss Astbury told the inquest that she noticed that there was something untoward about his behaviour when she returned with him to their home: "He had been drinking at someone's house and he seemed drunk but seemed a bit different somehow. So I asked him if he had taken anything and he said he had taken a pill. But that was all he would say to me."

That night he suffered a restless night's sleep, the inquest heard. While he appeared very warm, the ends of his fingers were purple, Miss Astbury noticed on waking, she told the inquest.

She left to go to work but became concerned when she could not get in touch with her partner, despite repeated phone calls.

When she returned to their home at lunchtime, she became worried when she realised her fiance had not been downstairs.

"As I went into the bedroom I knew something was wrong. He had this white froth around his mouth so I rang for an ambulance and tried to resuscitate him."

The inquest heard that Mr Burgoyne, who ran Burgoyne Plastering, had probably died that morning, some time after Miss Astbury had left to go to work.

The inquest heard from his mother Ann that Mr Burgoyne was "full of laughter, full of mischief but also full of sadness."

He suffered a breakdown in February 2005 and was nursed back to health by his family after a prolonged stay in hospital.

His mother Ann said his weight had gone from 11 stone to 19 stone after he began taking anti-psych-otic medication and he struggled to cope after his breakdown.

Recording a verdict of accidental death, East Lancashire coroner Richard Taylor said: "I have no doubt that when he took these drugs he had no idea that they would lead to his death."
