Kidbrooke Teacher Sabina Nessa is thought to have been murdered during a five-minute walk to meet a friend at a pub, police have said.
Officers investigation the killing of the 28-year-old have released details of the route she was travelling on at the time of the attack in the hope further witnesses come forward.
The Metropolitan Police said Sabina left her home on Astell Road in south east London last Friday and walked through Cator Park towards The Depot bar in Pegler Square, Kidbrooke Village, when she was attacked.
Her body was found near the OneSpace community centre at Kidbrooke Park Road in the Royal Borough of Greenwich at around 5:30pm on Saturday.
"Sabina never arrived at the pub and is thought to have been murdered as she walked through the park," the force said.
A post-mortem examination, carried out on Monday, was inconclusive.
In the last few days there has been outpouring of tributes but also shock and alarm after another shocking case.
Sadiq Khan tweeted that he was "heartbroken" by the news and that "women and girls deserve to feel safe at all times."
A candlelit vigil is going to be held on Friday to mark the life of the 28-year-old.
Detective Inspector Joe Garrity said: "Sabina's journey should have taken just over five minutes but she never made it to her destination.
"We know the community are rightly shocked by this murder - as are we - and we are using every resource available to us to find the individual responsible."
He added the investigation was making good progress, and said: "We believe there are still others out there who may have information that could help.
"If you think you saw Sabina or any suspicious behaviour in or around the park on Friday evening please speak to us."
