The baby son of a heavily pregnant woman who was stabbed to death in has died.
Kelly Mary Fauvrelle, 26, who was eight months pregnant, died at her home in Raymead Avenue, Croydon, in the early hours of Saturday.
Her baby – named Riley in one of Ms Fauvrelle’s last Facebook posts – was delivered by paramedics at the scene. There were hopes he would survive but he died in the early hours of Wednesday.
The Metropolitan Police released footage of a man seen running away from the house that night.
Det Ch Insp Mick Norman said the “tragic development makes it even more important that anyone with information comes forward as a matter of urgency”.
The CCTV released by Scotland Yard earlier shows a figure walking towards Ms Fauvrelle’s home at about 03:15 BST on Saturday, then running away 10 minutes later.
Ms Fauvrelle died at the scene but Riley was delivered by paramedics and was initially said to be in a critical condition.
