UPDATE: As predicted, officials announced on Thursday, May 1, that heroin was likely involved in Peaches Geldof's April 7 death at age 25. While initial autopsy results were inconclusive, further tests revealed she had the drug in her system, authorities said at a brief inquest. "The levels identified were likely to have played a role in her death," Detective Chief Inspector Paul Fotheringham told the BBC.
Peaches Geldof died as the result of a heroin overdose, according to The Times of London.
The British newspaper says the cause of death will be officially revealed Thursday, May 1, at an inquest.
The 25-year-old socialite and daughter of world-famous musician Bob Geldof was found unresponsive at her home on April 7, in Wrotham, Kent, England.
At the time of her death, Kent Police said in a statement released to Us Weekly: "At this stage, the death is being treated as an unexplained sudden death. Officers are working to establish the circumstances around the death."
