The hours leading up to the murder of a young model are to be featured on the BBC's Crimewatch programme.
An e-fit of Sally Anne's attacker
Eighteen-year-old Sally Anne Bowman was stabbed to death just yards from her home in South Croydon, south London, in September.
Tuesday's programme will show her getting out of her ex-boyfriend's car, being attacked and the suspect throwing away her things after the murder.
It also shows a female motorist being robbed just hours before.
Police think her attacker may be a serial rapist after tests linked her murder to an attack in Purley in 2001.
Det Ch Insp Stuart Cundy, who is leading the inquiry, will be interviewed on the programme.
He said: "The attack on Sally Anne was absolutely horrendous. The suspect stabbed her several times, he bit her several times, he sexually assaulted her and he killed her."
Police are also trying to trace Miss Bowman's Prada handbag, black purse, black Samsung D500 mobile phone and passport.
Miss Bowman was attacked in the early hours of 25 September after her ex-boyfriend Lewis Sproston, 20, dropped her off at home.
It is thought the killer may have been lying in wait for her as she returned home after a night out in Croydon in the early hours of 25 September.
The murder suspect is described as white, in his 20s or 30s, with short brown hair and is between 5ft 9in and 6ft tall.
