Yesterday the results of a post mortem confirmed he died of “natural causes by acute pulmonary oedema”.
But it will be several weeks before it is known whether alcohol or drugs were in his bloodstream when he died.
The post mortem offered no clues about the underlying cause of the oedema and the family of the 33-year-old will have to wait up to a fortnight for further test results.
His death may have been the result of an unknown underlying medical condition but this has yet to be confirmed.
A police source confirmed that the singer had been sick in his Majorca holiday apartment where his body was found on Saturday afternoon.
But a court spokeswoman said that alcohol was not a factor in his death.
“Stephen's death has nothing to do any alcohol he drank that night, it has nothing to do with drugs and he did not choke on his own vomit,” she said.
“If drink or drugs play any part in a death, they always put it in the cause of death.
“In this case they haven't. I'm not saying Stephen didn't vomit but I can categorically state he did not choke on his own vomit.”
It is expected that the test results will be available in around a fortnight.
Yesterday Stephen’s distraught husband Andrew Cowles saw his body for the first time after a judge gave the go-ahead for it to be released to his family.
The 32-year-old was tearful as he left a court in Palma at lunchtime yesterday after giving judge Carmen Abrines a witness statement about what happened in the hours leading up to the discovery of the body.
