London • An autopsy on Peaches Geldof was inconclusive and toxicology tests will be conducted in an attempt to determine what killed the 25-year-old celebrity, police said Wednesday.
Geldof was pronounced dead by paramedics at her home in southeast England on Monday.
Kent Police said a post-mortem examination had not revealed the cause and a toxicology report could take several weeks.
Geldof, the daughter of Irish musician Bob Geldof and the late TV presenter Paula Yates, had worked as a model, writer and television show host.
She grew up in the glare of Britain's press, which reveled in the late-night antics of her teenage years, and in the shadow of her mother's death from a drug overdose when Peaches was 11.
