Wayne Couzens, a serving Metropolitan Police officer, has admitted murdering Sarah Everard.
The 48-year-old married father of two, from Kent, entered the guilty plea during a hearing at the Old Bailey on Friday morning.
He had previously admitted kidnapping and raping Miss Everard, but had been awaiting psychiatric reports before entering a plea in relation to her death.
Couzens appeared via videolink from Belmarsh Prison where he has been held on remand since he was charged with murder in March.
Wearing a grey prison issue sweatshirt and beige trousers he sat hunched with his head bowed staring at his feet.
In court members of Miss Everard’s family looked on.
Asked by the clerk of the court how he pleaded guilty to the charge of murder, Couzens, paused for a few seconds before replying: "Guilty."

Miss Everard, a 33-year-old marketing executive, was abducted from a street in south London on the evening of March 3 as she walked home after spending the evening with friends at their flat in Clapham.
Her remains, which were identified using dental records, were found in woodland near Ashford in Kent a week after she disappeared.
Couzens was arrested at his home in Deal after CCTV footage linked his hire car with her abduction.
He was charged with kidnap and murder on March 12 and has been held in custody ever since.
He will be sentenced at a later date.
