PC Wayne Couzens has pleaded guilty to the kidnap and rape of Sarah Everard.
The Old Bailey heard Couzens, 48, accepted responsibility for the killing of Ms Everard but was not asked to enter a plea to a charge of murder.
Sarah was reported missing in Clapham, south London, on March 3.
A major police investigation was launched and her body was found a week later in woodland in Kent.
Couzens was not asked to enter a plea for a count of murder but his defence told the court he had admitted responsibility for the killing.
A medical report on Couzens is awaited.
He pleaded guilty to kidnapping Ms Everard "unlawfully and by force or fraud" on March 3.
He also pleaded guilty to a second charge of rape between March 2 and 10.
