Fiona Holm was last seen alive on the night of 20 June in Catford, southeast London. A man has been charged with her murder and the murder of Naomi Hunte, who was found stabbed to death at a flat in Greenwich in February last year.
Detectives have released CCTV as they try to find out what happened to a 48-year-old mother who has been missing since June and is alleged to have been murdered.
