The baby of a pregnant woman who was stabbed to death in London has died.
It comes after police investigating the murder of Kelly Mary Fauvrelle in the early hours of Saturday morning released CCTV footage of a man they wish to trace.
Ms Fauvrelle (26), who was eight months pregnant, was found by police and paramedics at her home in Croydon with stab wounds at 3.30am.
She died at the scene, but ambulance staff were able to deliver her baby boy.
The child, who family members named Riley, was in a critical condition before his death just after 3.00am on Wednesday.
New CCTV shows a man walking towards Ms Fauvrelle's address at around 3.15am on Saturday.
Just over 10 minutes later, the same man can be seen running away from the area.

Detective Chief Inspector Mick Norman is leading the investigation.
He said: "This morning, we heard the sad news that Kelly's baby son, Riley, has died in hospital. Our thoughts remain with their family.
"This tragic development makes it even more important that anyone with information comes forward as a matter of urgency.
"We have released footage as the next step in what has been a fast-paced, and extremely challenging investigation.
"We need to identify the man shown in the images urgently, even if only to eliminate him from our enquiries.
"I need to hear from anyone who knows who he is. If this is you, it is imperative that you contact my team immediately."
A 37-year-old man and a 29-year-old man who were arrested on Saturday and Sunday on suspicion of murder have been released.
The 29-year-old man was released on bail to a date in early August, pending further enquiries.
