DCI Paul Fotheringham, of the Kent and Essex Serious Crime Directorate, spoke of the days and final moments of Peaches Geldof - married to musician Tom Cohen - during the brief hearing in front of North West Kent coroner Roger Hatch.
On Thursday April 3, 2014, Thomas Cohen went with his two sons to stay for the weekend at his parents' house in south-east London.
This is a normal occurrence which enables Peaches and Thomas to complete work in their respective careers.
It is believed that Peaches spent Saturday afternoon, into the evening, and Sunday morning at her home address alone.
Throughout this period she maintained telephone contact with family and friends, including contact with Thomas's mother to arrange a family activity, but this was cancelled.
Peaches maintained contact with family and friends throughout Sunday and at 5pm Thomas's father Keith Cohen took the youngest child, Phaedra, back to Wrotham and spent half an hour with Peaches before leaving the child with her.
