There are still no answers about the sudden death of Bob Geldof's daughter.
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 presenter.
Her father said in a statement: "She was the wildest, funniest, cleverest, wittiest and the most bonkers of all of us. Writing 'was' destroys me afresh. What a beautiful child. How is this possible that we will not see her again? How is that bearable?" he said in a statement. "We loved her and will cherish her forever. How sad that sentence is. Tom and her sons Astala and Phaedra will always belong in our family, fractured so often, but never broken."
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.
More recently she had married for a second time, to musician Tom Cohen, had two young sons and worked as a broadcaster and fashion writer. She said in 2009 that her drug-taking years were behind her.
Police are treating her death as non-suspicious but unexplained. The force said detectives are investigating the circumstances and will hand their report to a coroner, who is likely to hold an inquest.
In Britain, coroners usually hold inquests to determine the facts of unexplained, sudden or violent deaths.
