Metropolitan Police officer Wayne Couzens will appear at the Old Bailey later accused of the kidnap and murder of Sarah Everard.
Ms Everard went missing while walking from the Clapham Junction area to her home in Brixton on 3 March.
The last known sighting of the 33-year-old was captured on a doorbell camera just after 9.30pm showing her walking alone toward Tulse Hill.
Her body was found in woodland near Ashford, Kent, a week later.
Couzens joined the force in September 2018, when he worked with a response team that covered Bromley.
He was later posted to the Parliamentary and Diplomatic Protection Command in February 2020.
Here, Couzens is said to have been mostly sent on uniformed patrol duties of diplomatic premises, including a range of embassies.
