An inquest in Nottingham last week heard how doctors did not know how or why she died despite exhaustive tests. A consultant pathologist, Dr Peter James, said she could have been a victim of Sudden Adult Death Syndrome.
"We still don't know what causes it. It could be related to a sleeping position - we don't know", he said.
The inquest heard how security staff found her body in lodgings at the Queen';s medical Centre, Nottingham, after being alerted by friends. The coroner recorded an open verdict.
