Update: British police confirmed that heroin likely played a role in the death of Peaches Geldof.
"Recent use of heroin and the levels identified were likely to have played a role in her death," according to Detective Chief Inspector Paul Fotheringham.
Original story: A coroner's inquest on Thursday morning will show that Peaches Geldof died from a heroin overdose, The Times of London is reporting.
The British TV presenter, 25, the daughter of Irish rocker and LiveAid organizer Bob Geldof, was found dead at her home near London on April 7. Her youngest son, Phaedra, then 11-months-old, was at her side. Initial autopsy and toxicology reports were inconclusive.
Prior to her death, Peaches Geldof "had become increasingly obsessed with the death of her mother, Paula Yates, from a heroin overdose in 2000," according to The Times.
Geldof was married to musician Thomas Cohen. They have two young sons, Astala, who turned 2 on April 21, and Phaedra, who turned 1 on April 24.
