The video shows 48-year-old mother Fiona Holm walking along the street after visiting an off-licence in southeast London.

Her family have appealed on social media for information, describing her as "very vulnerable" and hoping that she will be found alive, though a man has been charged with her murder.

Detective Chief Inspector Kate Blackburn said: "After a missing person investigation failed to locate Fiona, our enquiries have led us to believe that she had come to serious harm.

"Part of our ongoing investigation is piecing together a timeline of Fiona's movements in the days leading up to and including Tuesday 20 June when she was last seen alive.

"We are now releasing footage captured on what we believe to be Fiona's last living day and we need to speak to anyone who saw her or spoke to her around that time.

"Fiona was known to be a friendly woman who would take the time to speak with local people. She has been a familiar face in the Lewisham/Blackheath area.

"Do you know her? Did you see her from mid to late June? If you did, was she anxious or worried about anything, did she share any information with you about what was going on in her life?"

Ms Holm came from a big family who had issued appeals on Facebook in the days before she was formally reported missing.

The brief footage shows Ms Holm walking along Verdant Lane in Catford on the evening of 20 June. She has not been seen or heard from since and was reported missing nine days later.

Police have urged anyone around that area at the time with vehicle dashcam footage or doorbell video to come forward.

DCI Blackburn said: "If you saw, spoke to, or have information concerning Fiona please get in touch. No matter how insignificant your information might seem, please share it with us."

Carl Cooper, 65, of Broadfield Road, southeast London, has been charged with the murder of Ms Holm and the murder of Naomi Hunte, who was found stabbed to death at a flat in Greenwich in February last year.

He is in custody and due to appear at the Old Bailey on 3 October.
