Heroin use is likely to have played a role in the death of Peaches Geldof, the daughter of Live Aid founder Bob Geldof, an inquest in Britain has heard.
The 25-year-old model and journalist, who had two young children, was found dead at her home on April 7.
Her mother, TV presenter Paula Yates, died of a heroin overdose in 2000.
"Recent use of heroin and the levels identified were likely to have played a role in her death," police detective Paul Fotheringham told the opening of the inquest in Gravesend, southern England.
Peaches, who wrote for British magazines and newspapers and presented celebrity-driven television shows, had been looking after her 11-month-old son Phaedra at her home in Wrotham, Kent.
Her husband Thomas Cohen, 23, a musician, had spent the previous night apart from his wife and was looking after their eldest son, 23-month-old Astala.
He raised the alarm when he could not contact her by phone.
In 2000 Geldof's mother Yates accidentally overdosed on heroin while looking after her four-year-old daughter with INXS frontman Michael Hutchence at their London home.
Hutchence was found dead in a Sydney hotel room in 1997 in what a coroner ruled was suicide.
Peaches posted online an old photograph of her with her mother the night before her death.
