A toxicology test revealed that British television personality Peaches Geldof died of a heroin overdose, according to The Times of London.
Geldof's cause of death is expected to be formally announced Thursday. If heroin did, in fact, cause the 25-year-old's death, it would mirror the passing of her mother, Paula Yates, who died in 2000 after a reported overdose with then 4-year-old daughter Tiger Lily by her side.
Peaches, the daughter of political activist and musician Bob Geldof, was found dead on April 7 inside the home she shared with husband Thomas Cohen and their two children, Astala and Phaedra. The U.K.'s Sun reported that socialite's body was found with 11-month-old son Phaedra next to her. Police were called after Geldof failed to answer her husband's telephone calls at their home in Wrotham, Kent.
Authorities initially described her death as "unexplained and sudden." There have been no reports suggesting that illegal substances were found at the journalist's home up until this point.
After failing to establish cause of death on April 9, an inquest into her death was opened. According to the New York Daily News, the results of the inquest will be announced by Detective Chief Inspector Paul Fotheringham during a brief hearing at Gravesend Old Town Hall. A full inquest is due to be set for late July.
In a recent interview, Geldof admitted to never making peace with her childhood after her mother and father divorced. With a previous reputation as a party girl Geldof had been known to struggle with substance abuse in the past.
"'Yeah, I've taken drugs. Yes, I have had experiences, and a few of those experiences were unsavory, not ones I want to repeat, but I was growing up. I wanted the experience," Geldof told the Guardian during an interview in 2009. "I wasn't hugely into drugs, and I'm sober now. I'm not Amy Winehouse. I never have been. I wasn't a crackhead."
Geldof wrote that motherhood saved her life in a column for British parenting magazine, Mother and Baby.
"Now, with a new-found group of mummy mates, both locally and online -- all with the exact same struggles and issues, and who don't question if my child flings food at their hair or care if there's a screaming fit in the middle of street -- I'm happier than ever. I've achieved a sort of perfect balance," she wrote. "Right now life is good. And being a mum is the best part of it."
In a final post to her Instagram account, which has since been deactivated, Geldof shared a picture of herself as a child with Yates. Geldof was laid to rest on April 21st at St. Mary Magdalene and St. Lawrence in Davington, the same church where her mother's funeral was held.
